Re: [CODE4LIB] Structured Data Markup on library web sites

BTW the OpenLink Structured Data Sniffer (OSDS) 
is a great little browser plugin to see what structured data is lurking in
the html.

I believe that it supersedes the OpenLink Data Explorer Extension.

Re: [CODE4LIB] Structured Data Markup on library web sites

[Richard Wallis]

As a FYI, as far as I am aware the search engines do not access pages using
content negotiation (e.g.. asking for Application/rdf+xml) when looking for
structured data such as schema.org in their crawl process.

They expect to find it embedded in the HTML as Microdata, RDFa, or
increasingly JSON-LD in a script tag.

Re: [CODE4LIB] Deduping linked data in search - was RE: [CODE4LIB] Structured Data Markup on library web sites

[Richard Wallis]

It is always good sport trying to second guess what Google will do with
data……  ;-)

‘Localness’ is not always a matter of geographical nearness.  IP address
ranges for example are rumoured to have some influence in this area.

However it is as much about the relationship between well described
resources - in Schema.org terms having exampleOfWork relationships with
well described CreativeWork instances - and the Organization instances that
hold them.   A poorly described schema:library with little geolocation
information that is not linked to other references to the library, in
WikiData or Wikipedia for example, will hold back the relevance of the
resources held as much as poor description of the resources themselves.

Equally if the properties marked up in schema.org are all strings and not
canonical URIs for authors, subjects, publishers, etc. a search engine may
well be able to ingest the data, but linking it to other relevant entities
in their knowledge graph will be a challenge without them.

As to the major search engines tracking and consuming Bibframe.  As Kevin
implies, if they find it useful they will.   With 12+ Million sites across
many sectors publishing Schema.org data, I would imagine a few libraries
publishing Bibframe would be a bit of an edge case at the moment.

Kevin is also spot on to say “For a variety of reasons, organizations may
choose to use Bibframe as a more library-specific vocabulary but publish
the data for general consumption (read: for Google and others) in the
schema.org vocabulary.”  In simple terms choose your vocabulary based on
your audience. If you want to get data to non-library folks, go for the
most widely used and understood vocablary.

Re: [CODE4LIB] OCLC shutting down xISBN and xID (was Re: [CODE4LIB] Matching print and electronic editions of the same book)

[Richard Wallis]

@Sara:
You can lookup using OCLCNumber based and ISBN based URIs.  Note I am not
using the word ’search’.  You are not searching an index for references to
a number string, you asking for a description of the thing with identifier ‘
http://worldcat.org/oclc/##’.  May seem a little pedantic, but it is
fundamental to linked data.

As far as I am aware there is no direct access to lccn via this route. That
*would* be more of a search operation: ‘return me the Thing(s), and their
unique URI(s), that are sameAs the thing this identified by this’ lccn.

@Cindy:
All this data is openly available, as Linked Data under an Open Data
Commons Attribution License <http://www.oclc.org/data/attribution.en.html>,
in the way I described so you do not need an account key, or an API to
access it.

OCLC have APIs that also makes some of this data available via other
routes.  I will leave it to folks at OCLC to comment on those and any
limits, or not, associated with the Linked Data.

Re: [CODE4LIB] OCLC shutting down xISBN and xID (was Re: [CODE4LIB] Matching print and electronic editions of the same book)

[Richard Wallis]

Sara,

The canonical URI you are looking for is http://worldcat.org/oclc/8410511
which silently redirects [via a http 303] to where the data is currently
stored (experiment.worldcat.org).  This approach enables the canonical
WorldCat identifiers to be maintained over time in a fixed namespace,
whilst providing flexibility as to where the actual data is stored.

You can use http content-negotiation to get the serialisation [html,
rdfxml, triples, turtle] that you require, or as an option you can suffix
the url with .jsonld etc.  - See my blogpost
<http://dataliberate.com/2013/06/content-negotiation-for-worldcat/> for a
longer explanation.

The same pattern occurs when you follow the exampleOfWork triple to get the
work id.  The data references the canonical
http://worldcat.org/entity/work/id/3357516 URI. Accessing that redirects,
via a http 303, to the description of that resource at
http://experiment.worldcat.org/entity/work/data/3357516.

The moral of this is always *use the canonical URIs to look things up*.

You ask if ‘experiment.worldcat.org’ is going to be around for a while.
>From the above you can infer that it is the wrong question to ask. WorldCat
itself maintains the canonical URIs, for Works, OCLCNUMS, and other
entities. By using those in your code, you will be protected against any
architectural and or system changes behind the scenes.

Then, as Terry suggests, following the relationships in the Linked Data is
the way to achieve many of the same ends as using xID.

ie. Using an OCLCNUM, generate the URI of the associated WorldCat entity ‘
http://worldcat.org/oclc/x'.  From that entity description extract the
schema:exampleOfWork triple. Use the URI from that to obtain the Work URI.
Obtain the description of the Work from that URI and the extract the values
of the contained schema:workExample triples.

[CODE4LIB] W3C Community Group Launched for Archives and Schema.org

[Richard Wallis]

*Apologies for cross posing*

Following interest expressed at the LODLAM Summit 2015
http://summit2015.lodlam.net/ a W3C Community Group has been created to
discuss potential extension of the Schema.org vocabulary to describe
archives and their contents.

The group named *Schema Architypes* can be accessed via the Architypes W3C
Community Group Site https://www.w3.org/community/architypes/:

The mission of the group is to discuss and prepare proposal(s) for
extending Schema.org schema for the improved representation of digital and
physical archives and their contents. The goal being focused upon the
creation and future maintenance of an archive.schema.org extension.


All who are interested are welcome to join the group and the discussion.

Note: In order to join the group
https://www.w3.org/community/architypes/join, you will need a W3C account
https://www.w3.org/accounts/request. Please note, however, that W3C
Membership
https://www.w3.org/community/about/faq/#is-w3c-membership-required-to-participate-in-a-community-or-business-group
is
*not* required to join a Community Group.

 Hi all,

 Seeing this thread I checked with the ISNI team and got the following

 SNI identifies “public identities”.The scope as stated in the
 standard
 is



 “This International Standard specifies the International Standard name
 identif*i*er (ISNI) for the identification of public identities of
 parties;
 that is, the identities used publicly by parties involved throughout the
 media content industries in the creation, production, management, and
 content distribution chains.”



 The relevant definitions are:



 *3.1*

 *party*

 natural person or legal person, whether or not incorporated, or a group
 of
 either

 *3.3*

 *public identity*

 Identity of a *party *(3.1) or a fictional character that is or was
 presented to the public

 *3.4*

 *name*

 character string by which a *public identity *(3.3) is or was commonly
 referenced



 A party may have multiple public identities and a public identity may
 have
 multiple names (e.g. pseudonyms)



 ISNI data is available as linked data.  There are currently 8 million
 ISNIs
 assigned and 16 million links.

  Hi Stuart,

 I don't have a copy of the official standard, but from the documents on
 the ISNI website I remember that there are name variations and 'public
 identities' (as the lemma on Wikipedia also uses). I'm not sure where
 the
 borderline is or who decides when different names are different
 identities.

 If it were up to me: pseudonyms are definitely different public
 identities, name changes after marriage probably not, name change after
 gender change could mean a different public identity. Different public
 identities get different ISNIs; the ISNI organisation says the ISNI
 system
 can keep track of connected public identities.

 Discussions about name variations or aliases are not new, of course. I
 remember the discussions about 'aliases' vs 'Artist Name Variations'
 that
 are/were happening on Discogs.com, e.g. 'is J Dilla an alias or a ANV
 of
 Jay Dee?' It appears the users on Discogs finally went with aliases,
 but
 VIAF put the names/identities together: http://viaf.org/viaf/32244000
 -
 and there is no ISNI (yet).

 It gets more confusing when you look at Washington Irving who had
 several
 pseudonyms: they are just listed under one ISNI. Maybe because he is
 dead,
 or because all other databases already know and connected the
 pseudonyms
 to the birth name? (I just sent a comment asking about the record at

 to marriage, transitions gender, etc), should they be assigned a new
 identifier?

 If the answer is 'No' why is this called a 'name identifier'?

 Ideally someone with access to the official text would update the
 article at
 https://en.wikipedia.org/wiki/International_Standard_Name_Identifier
 With a brief quote referenced to the standard with a page number.

 [The context of this is ORCID, which is being touted as an entity
 identifier, while not being clear on whether it's a name or entity
 identifier.]

Re: [CODE4LIB] Is ISNI / ISO 27729:2012 a name identifier or an entity identifier?

[Richard Wallis]

Hi Eric,

What distinguishes one from another?

The communities behind them, the [often overlapping] communities they
are intended to serve, and the technical implementation.

As a librarian, why should I care?

I would, as a non-librarian, suggest that once you are happy with
the ‘authority’ of them, you shouldn’t have to care. Ideally, we are not
there yet, systems should be flexible and accommodating enough to link to
any appropriate authority.

I will probably get flamed for over generalisation here but - VIAF is
an aggregation of National Libraries Authority files.  - ISNI is a more
publisher focused but similar effort.  - OCID comes from and and tries to
serve individual academic institutions, their researchers and falsity
authors.

 Increasingly I like linked data, and consequently, here is clarification
 and a question. ORCID does support RDF, but only barely. It can output
 FOAF-like data, but not bibliographic. Moreover, it is experimental, at
 best:

   curl -L -H 'accept: application/rdf+xml'

Re: [CODE4LIB] Is ISNI / ISO 27729:2012 a name identifier or an entity identifier?

[Richard Wallis]

More from Janifer….

Thanks Richard for forwarding.  I don’t know how long my answer is allowed
to be.  Here are some extracts from a recent article (in publication):



Meryl Streep has only one public identity that she uses for her creative
works.  VIAF includes Streep, Meryl (Mary Louise) as the name form on her
birth certificate is Streep, Mary Louise.  Her married name Gummer, Mary
Louise, is mentioned in Wikipedia and could also be considered as a name
variant.  Changes in the preferred forenames and change of name due to
marriage are not considered as constituting a change of identity as there
is not necessarily a wish by the person to separate his or her creative
output corresponding with a name change.  Researchers, for example will
mention the ensemble of their publications in their curriculum vitae where
they have been published over a lifetime involving name changes.

Alternative name forms that do not usually indicate a change in identity
can take variant forms including names in different scripts or
transliterated with different schemes, changes due to change of sex,
marriage and deed poll.



Kingsley Amis in the figure above is an example of an author writing under
3 different identities, writing as himself and writing under two different
pseudonyms.  His works attributed to each of the three different identities
are clearly separated.  In this case, the association of the pseudonyms
with the real person is public but that is not always the case.  For
example, J.K. Rowling chose to create a pseudonym Robert Galbraith (35) so
that she could write in a different genre and have her works in the new
genre judged without any influence of the successful Harry Potter
series.When the relationship between a pseudonym and a real person is
or becomes public, the works tend to become associated with the real person
as well as the pseudonym; for example they may be republished or released
in collected works.  One example is John Wyndham, the main pen name of John
Wyndham Parkes Lucas Beynon Harris (10 July 1903 – 11 March 1969).  Under
an earlier pen name, John Beynon, he wrote*Secret People *but this is now
published under John Wyndham.   As a general rule, separate authority
records should be made for each identity used as a public identity.  This
allows the history of works to be accurately traced, enabling catalogs to
respond to questions such as “under which identity was the work conceived
and first published?”  The authority records related to each of the public
identities should be linked where the relationship is public.
Encyclopedias such as Wikipedia tend to have only one entry for a person,
grouping all public identities.  This entails the need for one-to-many
relationships in linking especially from library authority records to
encyclopedias.

Best regards,



Janifer

 Hi Stuart,

 I don't have a copy of the official standard, but from the documents on
 the ISNI website I remember that there are name variations and 'public
 identities' (as the lemma on Wikipedia also uses). I'm not sure where the
 borderline is or who decides when different names are different identities.

 If it were up to me: pseudonyms are definitely different public
 identities, name changes after marriage probably not, name change after
 gender change could mean a different public identity. Different public
 identities get different ISNIs; the ISNI organisation says the ISNI system
 can keep track of connected public identities.

 Discussions about name variations or aliases are not new, of course. I
 remember the discussions about 'aliases' vs 'Artist Name Variations' that
 are/were happening on Discogs.com, e.g. 'is J Dilla an alias or a ANV of
 Jay Dee?' It appears the users on Discogs finally went with aliases, but
 VIAF put the names/identities together: http://viaf.org/viaf/32244000 -
 and there is no ISNI (yet).

 It gets more confusing when you look at Washington Irving who had several
 pseudonyms: they are just listed under one ISNI. Maybe because he is dead,
 or because all other databases already know and connected the pseudonyms
 to the birth name? (I just sent a comment asking about the record at
 http://isni.org/isni/000121370797 )


 [Here goes the reference list…]

 Hope this helps :)

Re: [CODE4LIB] barriers to open metadata?

[Richard Wallis]

To unpack the several questions lurking in Karen’s question.

As to being able to use the WorldCat Works data/identifiers there is no
difference between a or b - it is ODC-BY licensed data.

Getting a Work URI may be easier for a) as they should be able to identify
the OCLC Number and hence use the linked data from it’s URI 
http://worldcat.org/oclc/{ocn} to pick up the link to it’s work.

Tools such as xISBN http://xisbn.worldcat.org/xisbnadmin/doc/api.htm can
step you towards identifier lookups and are openly available for low volume
usage.

Citation lookup is more a bib lookup feature, that you could get an OCLC
Number from. One of colleagues may be helpful on the particulars of this.

Apologies for being WorldCat specific, but Karen did ask.

~Richard.

Re: [CODE4LIB] viaf

You are correct that in the xmlns namespace definitions in the xml 
http://viaf.org/viaf/231063554/rdf.xml references a namespace that is no
longer used in the output.  There is a single commented out reference to '
viaf:NameAuthorityCluster' in the output.

This post covers the change that deprecated the use of this:
http://outgoing.typepad.com/outgoing/2011/04/changes-to-viafs-rdf.html

From the other xmlns definitions it can be seen that use is made of void,
owl, foaf, skis-xl, skis, RDA ElementsGR2, FRBRentitiesRDA to describe VIAF
resources.

I'll pass this on to some of the team behind VIAF to see if they have
further comment

[CODE4LIB] Schema.org and its extension for bib data (was Coins)

[Richard Wallis]

On 21 November 2012 07:37, Dave Caroline dave.thearchiv...@gmail.comwrote:


 But... it is no good choosing a random extension if the Search engine
 is or will be blind to that particular method.
 As someone who likes to leverage SEO the right way so one does not
 get penalised, some standardisation  is needed.


This is exactly what is behind the Schema.org initiative - 'the search
engines' (Google, Bing, Yahoo and Yandex) have agreed to recognise
structured markup using the Schema.org vocabulary and will expand that
recognition over time as the vocabulary evolves.

There is a process, under the wing of the W3C, to propose extensions to the
vocabulary to improve it's descriptive capabilities for particular domains.
 As Jeff mentioned, this has already occurred in the areas of news,
commerce, jobs.   Coming mostly from a groups organisations in those
domains, these proposals were successful as they came with some authority
to the [by definition] broadly focused group behind schema.org.

It is for that reason, I formed the W3C Group Schema Bib Extend 
http://www.w3.org/community/schemabibex/ to create such a consensus in the
community concerned with publishing bibliographic data on the web.  All are
welcome to join this group, membership of the W3C is not a requirement.
 Elements of this COinS conversation are obviously relevant to such
proposals.

*Bit of Background for those new to this:*

* Schema.org http://schema.org/ introduced in mid 2011 by Google, Yahoo,
Bing, and Yandex.
* A generic vocabulary for describing most things in structured data on the
web that the search engines will recognise
* By June 2012, Google  Bing report that 7%-10% of crawled pages contain
schema.org markup 
http://dataliberate.com/2012/06/schema-org-consensus-at-semtechbiz/
* Schema Bib Extend W3C Group formed Sept 2012 as a short lived group to
propose bibliographic (in the widest sense) extensions to Schema.
* SchemaBibEx not just focusing on library needs, includes publishers etc.
- anyone wanting to publish bibliographic structured data on the web.
* Schema.org, due to its broad generic nature will only complement, not
replace, other detailed library standards.
* By publishing bib metadata in this way we have at last a way to tell the
world, not only the search engines, about our resources using markup that
will be broadly understood.
* Using markup 'the world will understand, and can use' underpins the
release of WorldCat linked data earlier this year

Re: [CODE4LIB] Get Yourself a Linked Data Piece of WorldCat to Play With

[Richard Wallis]

Hi Karen,

I was not ignoring you previous question about where, in Marc terms, data
was coming from.  I need to talk with someone who was in the core of the
processing that produces the data.  Unfortunately I am currently being
thwarted by vacations.

In the meantime, can you let me have a few examples of where you are seeing
discrepancies between the download triples and the RDFa embedded in
WorldCat.org pages.

 One of those differences happens to be the source of the place of
 publication, if I am reading it right. So, again, a request for
 documentation on the fields included and their MARC source.

 Thanks,

Re: [CODE4LIB] Worldcat schema.org search API

[Richard Wallis]

Hi Karen

At this stage there is no specific api as such to get at the embedded RDFa
data in WorldCat - you can use the normal UI of WorldCat itself or one of
the WorldCat Search API options such as
OpenSearchhttp://oclc.org/developer/documentation/worldcat-search-api/opensearch.
  This experimental first step at exposing WorldCat data as linked data
will evolve. As more development and discussion guides us, more data and
ways to get at it will appear.

You can get at the raw RDF from the embedded RDFa it in a couple of ways.
 The W3C RDFa 1.1 Distiller http://www.w3.org/2012/pyRdfa/ is one.
 Another is using the ARC2 PHP
Libraryhttps://github.com/semsol/arc2/wiki/Getting-started-with-ARC2
for
those that want to write some simple code.  Bruce Washburn has published a
posthttp://www.oclc.org/developer/news/linked-data-now-worldcat-facebook-app
sharing
how he used ARC2 in the enhanced WorldCat Facebook App to extract the RDF
from WorldCat and process it to link on and use the same technique on Viaf
and FAST.  He includes code snippets and a link to the full source for
those that are interested.

A minor point on licensing - the linked data is licensed under
ODC-BYhttp://opendatacommons.org/licenses/by/,
not CC-BY.  ODC-BY is a data oriented license, as against CC which is more
creative work oriented.

Sorry my email was hard to find - it is richard.wal...@oclc.org.  Also if
you have questions or comments about OCLC linked data formatting or
publishing you can drop an email to d...@oclc.org.

Re: [CODE4LIB] Worldcat schema.org search API

[Richard Wallis]

Karen,

RDFa and the basic schema.org vocabulary, plus the intention of the
proposed library extension, are not OCLC specific - they are generic tools
and techniques applicable across many domains.

I would therefore avoid library focussed tool sites, which would run the
risk of not keeping up with wider developments.  RDFa.info seems to be
shaping up as a good resource.

Schema.org itself also is a good resource.

On the point of how to gain the best from linked data, many especially in
the library community, immediately look towards search as the default *
paradise* for dealing with data.  Many of the benefits of linked data
emerge not from search, but from identifying relationships and following
links.  I heard this described the other day as 'facets on steroids' - not
entirely accurate, but it conjures up the right kind of image ;-)

I am not saying ignore search, far from it, just suggesting that innovation
with linked data often comes from what you can do once you have found (often
by traditional methods) a thing .

Re: [CODE4LIB] RDF advice

[Richard Wallis]

Hi Ethan,

I will defer to those with greater insight, into what has been discussed
earlier in this thread, than myself as to some of the semantics you are
trying to crystallise here.

What I can offer instead is a bit of advice as to lubricating the process.

Firstly, stay as far away from XML as possible whilst trying to shape your
model/ontologies - it a) introduces hierarchical thinking/visualisation in
to what may well not be a problem of hierarchy, b) is difficult to read, c)
in the world of RDF, best reserved for machine to machine communication.

Secondly, put away the computer and get out the white/blackboard and pen.
 Start drawing some ellipses, rectangles, and arrows.  When you have a
model that looks something like the real world you are trying to represent
(not the traditional metadata records you previously held), transform that
in to a form of RDF that a computer will understand.

This is an approximation of the process the British Library used to work
their way towards their data
modelhttp://dataliberate.com//wp-content/uploads/2012/01/British-Library-Data-Model-v1.01.pdf
for
the British National Bibliography.

Oh, and the XML?  - Let a tool like Raptor produce it for you from the more
human friendly turtle you come up with.

~Richard.

 Hi Patrick,

 Thanks.  That does make sense.  Hopefully others will weigh in with
 agreement (or disagreement).  Sometimes these semantic languages are so
 flexible that it's unsettling.  There are a million ways to do something
 with only de facto standards rather than restricted schemas.  For what it's
 worth, the metadata files describe coin-types, an intellectual concept in
 numismatics succinctly described at
 http://coins.about.com/od/coinsglossary/g/coin_type.htm, not physical
 objects in a collection.

 Trying to synthesize what Karen, Richard and Simon have bombarded us with
 here, leads me to conclude that linking to existing (or to be created)
 external data (ontologies and representations) is a matter of: being sure
 what you’re the system's current user's context is, and being able to
 modify the external data brought into the users virtual EMU(see below ***
 before reading further).


Sorry for the bombarding ;-)

being sure what you’re the system's current user's context is - sounds
like a nice idea, but when you are publishing data you have little control,
and even less knowledge, of the consuming 'user' and their context.

Taking things to the next level, by building services and applications for
users, you hopefully will have some understanding of the virtual and actual
users' contexts and can take [what I like to call editorial] decisions
about how much data in what format to deliver to them, and which links to
follow to enrich your service.

So, back down at the data level, model your domain to include all the
information you are aware of for the entities you are describing, plus link
them to other domains that can enrich those descriptions.   Leave it to the
consumers of your data to decide what is best for them in their context.


 I think Simon is right that records will increasingly become virtual in
 that they are composed as needed by this user for this purpose at this
 time.


Yes - you could envisage, for some domains,  a minimalistic description of
their resource could be sufficient in the form of a single triple:
http://mylib.org/resource/12345 owl:sameAs 
http://bnb.data.bl.uk/id/resource/008740700 .


 I think Simon (maybe Richard, maybe all of you) was working towards a
 single unique EMU for the entity which holds all unique information about
 it for a number of different uses/scenarios/facets/formats. Of course
 deciding on what is unique and what is obtained from some more granular
 breakdown is another issue. (Some experience with this onion skin
 modeling lies deep in my past, and may need dredging up.)


I am suggesting that you in your domain/catalog/library would probably
assign a unique identifier, in your domain, for each of the things you
describe:
 http://mylib.org/resource/12345
 http://mylib.org/person/CarpenterEdward1910-1998

Describe those things:
http://mylib.org/resource/008740700 rdf:type bibo:Book .
 http://mylib.org/person/CarpenterEdward1910-1998 foaf:name Edward
Carpenter .

Describe the relationships between those things:
 http://mylib.org/resource/008740700 dct:creator 
http://mylib.org/person/CarpenterEdward1910-1998 .

Then link them to external descriptions of the same concepts:
 http://mylib.org/resource/12345 owl:sameAs 
http://bnb.data.bl.uk/id/resource/008740700 .
 http://mylib.org/person/CarpenterEdward1910-1998 owl:sameAs 
http://viaf.org/viaf/53127337 .

That way you end up with internal identifiers that you can link to, from
things like comments, circulation records, physical location information,
etc.  These are then linked out to distributed descriptions which you, or
consumers of your data, can then merge with your data to provide richer
information.   I know the above examples are a bit simplistic, but
nevertheless it could be near good-enough for some use cases.


*** I suggest (and use above) the Entity Metadata Unit = EMU. This contains
 the totality of unique information stored about this entity in this single
 logical location.


In my current location, and the current economic climate, I am wary of an
acronym the same as European Monetary Union.  ;-)

However, I think you are thinking in the right direction - I am resigning
myself to just using the word 'description'.

Simon,

You wrote:

 Q: In your definition, can *descriptions *be put* * into 1:1 correspondence
 with records (where a record is a atomic asserted set of propositions about
 a resource)?


I do not believe so, especially when referencing back to where we started -
the Marc Record.

A Marc record more often than not, contains propositions about many things:
 * The book itself (lets assume that's what the record is about) - isbn,
number of pages, cost, format, shelf location
 * The author - name, birth/death date
 * The publisher - name, location
 * Publication event - date, publisher, location
 * Subject(s)

In my view this record contains information to populate 5 or more separate
descriptions, plus the related links between them.

Karen, thanks for diving in ;-)

I do NOT see a description as atomic in the sense that a record is

  description always has the POTENTIAL to have a bit of unexpected data
  added; a record cuts off that possibility.


Yes.  Take the author thing from above. It may have it's basic, Marc record
derived information, enhanced, by merging with external resources, to add
an author's website or image.


 
  That said, I am curious about the permeability of the edges of a named
  graph. I don't know their degree of rigidity in terms of properties
 allowed.
 

 Named graphs were supposed to be invariant under the original proposal;
  there is a lot of mess around the semantics right now. Dan Brickley wrote
 a very nice example : http://danbri.org/words/2011/11/03/753 .


As per the comments on Dan's blog, it is dangerous to jump on named graphs
as the solution to perceived problems.  If I wanted to load RDF from three
separate libraries in to a triple store I would  assign them to three named
graphs, but then probably query the default global graph giving a merged
view.

Using named graphs to try to recreate our original source record seems to
defeat the [opening up] purpose of moving to Linked Data modeling in the
first place.  I also think it would add in a layer of complexity without an
obvious justifying data consumer use case.

 for the moment. It will only be stored as a processing intermediate result
 (as a record, since its contents are now fixed), and not long term, since
 it would be broken up to bits of entity data and stored in a distributed

Yes.  However those descriptions have the potential to be as permanent as
the records that they were derived from.  As in the BL's case where the RDF

 Quoting Richard Wallis richard.wal...@talis.com:


  You get the impression that the BL chose a subset of their current
 bibliographic data to expose as LD - it was kind of the other way around.
 Having modeled the 'things' in the British National Bibliography domain
 (plus those in related domain vocabularis such as VIAF, LCSH, Geonames,
 Bio, etc.), they then looked at the information held in their [Marc] bib
 records to identify what could be extracted to populate it.


 Richard, I've been thinking of something along these lines myself,
 especially as I see the number of translating X to RDF projects go on. I
 begin to wonder what there is in library data that is *unique*, and my
 conclusion is: not much. Books, people, places, topics: they all exist
 independently of libraries, and libraries cannot take the credit for
 creating any of them. So we should be able to say quite a bit about the
 resources in libraries using shared data points -- and by that I mean, data
 points that are also used by others. So once you decide on a model (as BL
 did), then it is a matter of looking *outward* for the data to re-use.


Yes!




 I maintain, however, as per my LITA Forum talk [1] that the subject
 headings (without talking about quality thereof) and classification
 designations that libraries provide are an added value, and we should do
 more to make them useful for discovery.


The wider world is always looking for good ways to categorise things.  The
library community should make it easy for others to utilise their rich
heritage of such things. LCSH is an obvious candidate, so is VIAF amongst
others.  The easier we make it, the more uptake there will be and the more
inbound links in to library resources we will get.  By easier, I am
suggesting that efforts to map these library concepts (where they fit) to
their wider world equivalents found in places like Dbpeadia, New York
Times, and Geonames, will greatly enhance the use and visibility of library
resources.




 I know it is only semantics (no pun intended), but we need to stop using
 the word 'record' when talking about the future description of 'things' or
 entities that are then linked together.   That word has so many built in
 assumptions, especially in the library world.


 I'll let you battle that one out with Simon :-), but I am often at a loss
 for a better term to describe the unit of metadata that libraries may
 create in the future to describe their resources. Suggestions highly
 welcome.


Your are not the only one who is looking for a better term for what is
being created - maybe we should hold a competition to come up with one.

 A named graph gets thrown around a lot, and even though this is
 technically correct, it's neither nice nor sexy.


It also carries lots of baggage from the Linked Data/Triple store
communities that would get in the way.


 In my past a bucket was much used, as you can easily thrown things in or
 take it out (as opposed to the more terminal record being set), however
 people have a problem with the conceptual size of said bucket, which more
 or less summarizes why this term is so hard to pin down.


Yes, most would assume that a bucket would be the place to put their [think
of a better word than] records.



 I have, however, seen some revert the old RDBMS world of rows, as they
 talk about properties on the same line, just thinking the line to be more
 flexible than what it used to be, but we'll see if it sticks around.


Collection of triples?


 Personally I think the problem is that people *like* the idea of a closed
 little silo that is perfectly contained, no matter if it is technically
 true or not, and therefore futile. This is also why, I think, it's been so
 hard to explain to more traditional developers the amazing advantages you
 get through true semantic modelling; people find it hard to let go of a
 pattern that has helped them so in the past.


A classic example of only being able to describe/understand the future in
the terms of your past experience.


 Breaking the meta data out of the wonderful constraints of a MARC record?
 FRBR/RDA will never fly, at least not until they all realize that the
 constraints are real and that they truly and utterly constrain not just the
 meta data but the future field of librarying ... :)

 on AACR or ISBD or other rules. The move to any future format will have to
 include some kind of transformation of that data. The result will be
 something ugly, at least at first: AACR in RDF is not going to be good
 linked data.


I agree with your sentiment here but, from what you imply at
http://futurelib.pbworks.com/w/page/29114548/MARC%20elements,
transformation in to something that would be recognisable by the
originators of the source Marc will be difficult - and yes ugly.

The refreshing thing about the work done by the BL is that they stepped
away from the 'record', modeled the things that make up the BnB domain.
Then they implemented processes to extract rich data from the source Marc,
enrich it with external links, and load it to an RDF representation of the
model.

On the way, embedded in the extraction/transformation/enrichment processes
there was much ugly data, but that was not exposed beyond the process.  An
approach I applaud, unlike muddying the waters by attempting to publish
vocabularies for every Marc tag you can think of.


I believe that you and I share a concern: that current library data is
 based on such a different model than that of the Semantic Web that by
 looking at our past data we will fail to understand or take advantage of
 linked data as it should be.


Concern shared.   I would however lower my sights slightly by setting the
current objective to be 'Publishing bibliographic information as Linked
Data to become a valuable and useful part of a Web of Data'.   Using the
Semantic Web as a goal introduces even more vagueness and baggage.  I
firmly believe that establishing a linked web of data will eventually
underpin a Semantic Web, but  there is still a few steps to go before we
get anywhere near that.


  Unfortunately, the library cataloging world has no proposal for linked
 data cataloging. I'm not sure where we could begin.


This is not surprising and I believe, at this stage, it is not a problem.
Lets eat the elephant one bite at a time - I envisage a lengthy interim
phase where publishing linked bibliographic data derived from traditional
Marc records (using processes championed by a community such as CODE4LIB),
is the norm.  Cataloging processes and systems that use a Linked Data model
at the core should then emerge, to satisfy a then established need.

 Richard, this is an interesting statement about the BL data. Are you
 saying that they chose a subset of their current bibliographic data to
 expose as LD? (I haven't found anything yet that describes the process
 used, so if there is a document I missed, please send link!)


There is no document I am aware of, but I can point you at the blog post by
Tim Hodson [
http://consulting.talis.com/2011/07/british-library-data-model-overview/]
who helped the BL get to grips with and start thinking Linked Data.
Another by the BL's Neil Wilson [
http://consulting.talis.com/2011/10/establishing-the-connection/] filling
in the background around his recent presentations about their work.

You get the impression that the BL chose a subset of their current
bibliographic data to expose as LD - it was kind of the other way around.
Having modeled the 'things' in the British National Bibliography domain
(plus those in related domain vocabularis such as VIAF, LCSH, Geonames,
Bio, etc.), they then looked at the information held in their [Marc] bib
records to identify what could be extracted to populate it.



 This almost sounds like the FRBR process, BTW - modeling the domain, which
 is also step one of the Singapore Framework/Dublin Core Application Profile
 process, then selecting data elements for the domain. [1] FRBR,
 unfortunately, has perceived problems as model (which I am attempting to
 gather up here [2] but may move to the LLD community wiki space to give it
 more visibility).


The BL will tell you that their model is designed to add to the
conversation around how to progress the modelling bibliographic information
as Linked Data.  There is still a way to go.  They are currently looking at
how to model multi-part works in the current model and hope to enhance it
to bring in other concepts such as FRBR.


 The work that I'm doing is not based on the assumption that all of MARC
 will be carried forward. The reason I began my work is that I don't think
 we know what is in the MARC record -- there is similar data scattered all
 over, some data that changes meaning as indicators are applied, etc. There
 is no implication that a future record would have all of those data
 elements, ...


I know it is only semantics (no pun intended), but we need to stop using
the word 'record' when talking about the future description of 'things' or
entities that are then linked together.   That word has so many built in
assumptions, especially in the library world.


 Concern shared.   I would however lower my sights slightly by setting the
 current objective to be 'Publishing bibliographic information as Linked
 Data to become a valuable and useful part of a Web of Data'.   Using the
 Semantic Web as a goal introduces even more vagueness and baggage.  I
 firmly believe that establishing a linked web of data will eventually
 underpin a Semantic Web, but  there is still a few steps to go before we
 get anywhere near that.


 My concern is the creation of LD silos. BL data uses some known namespaces
 (BIBO, FOAF, BIO), which in fact is a way to join the web of data that
 many others are participating in, because your foaf:Person can interact
 with anyone else's foaf:Person. But there are a great number of efforts
 that are modeling current records (FRBRer, ISBD, MODS, RDA) and are
 entirely silo'd - there is nothing that would connect the data to anyone
 else's data (and the ones mentioned would not even connect to each other).
 So I don't know what you mean by part of a Web of data but to me using
 non-silo'd properties is enough to meet that criterion. Another possibility
 is to create links from your properties to properties outside of your silo,
 e.g. from RDA:Person to foaf:Person, for sharing and discoverability.


There a couple of ways that your domain can link in to the wider web of
data.  Firstly, as you identify, by sharing vocabularies.  There is a small
example in the middle of the BL model, where a Resource is both a
dct:BiblographicResource and also (when appropriate) a bibo:Book.

In Linked Data there is nothing wrong in mixing ontologies within one
domain.  If the thing you are modelling is identified as being a
foaf:person, there is no reason why it can not also be defined

I somehow missed out on this thread and it's predecessor, until a major
fail in the British rail system resulted in an unexpected coffee with Owen
yesterday - I hope he got home OK.However the benefit of being late to
a conversation is that you can see where the points of friction are.  So a
few thoughts on those:

Why bother?
Transforming Marc in to RDF is an interesting and challenging exercise, but
there is little point in doing it without having some potential benefits in
mind beyond the it would be great to have our stuff in a new format


RDF is a means to an end
We shouldn't loose sight of the RDF TLA, Resource Description Framework -
it is a framework for describing [our] resources.   It is the, de facto,
standard for publishing Linked Data.   Publishing descriptions of our
resources as Linked Data does fall in to the potential benefits arena -
reuse, mixing, merging, lowering barriers to use of data across, and from
outside of, the library community.


If it waddles and quacks, it is probably still a duck
Transforming a Marc record to XMLMarc just created the same record in in a
different wrapper.  Apart from the technical benefit (of being able to use
generic tools to work with it), it did not move us much further forward
towards opening up our data to wider use. Transforming Marc, of any flavor,
into an RDF representation of a record still leaves us with a record per
item - a digital card catalogue equivalent.


A record is a silo within a silo
A record within a catalogue duplicates the publisher/author/subject/etc.
information stored in adjacent records describing items by the same
author/publisher/etc.  This community spends much of it's effort on the
best ways to index and represent this duplication to make records
accessible.   Ideally an author, for instance, should be described
[preferably only once] and then related to all the items they produced


Linked Data should be the goal
At the event mentioned by Mike, Linked Data and Libraries[1], the British
Library launched their initial data model for the British National
Bibliography[2].  One of the key concepts of Linked Data is to represent
data as a set of interlinked things. These things are referred to as
objects of interest, they are things about which we can make statements.
In this model you get statements about things (eg. books, authors,
publishers, publishing events, subjects, places, etc.) and the links
between them - not a record per item.


Storing Marc in an RDF triple, or link to it?
The question I would ask is, which consumer of your data would this be
useful for?  Secondly, whatever your answer, it does not make sense to say
that this item, or author, or publisher 'thing' was derived from a
particular Marc record - you could perhaps at data set, or graph, level
(using the provenance vocabulary) define that it was transformed from a
particular source, at a time, using a method, by a person/process.


Who's Ontology
Do we only use library domain ontologies/vocabularies or do we employ dc,
foaf, bibo, etc. ?  Do we use dc:creator which most of the [non-library]
world will understand, or some esoteric [to them] rda properties to
describe corporate and many other nuance of authorship?   If you want to
enable general application developers/data consumers to use your data, you
need to apply the well known [if possibly course-grained or lossy] terms.
If you want to preserve the rich detail extracted from the source Marc, you
need to delve deeper in to bibliographically oriented properties.   Can you
do both? Yes.  Should you do both? Probably.

~Richard.

I think I better stop now and contemplate a blog post to further these
thoughts.

Although not library focussed uses of the Platform, it is also being

There has been a recent thread on the NGC4LIB list, stimulated by an

[CODE4LIB] Code4lib mugs?

[Richard Wallis]

We at Talis will be, as previously, sponsoring Code4lib next year - we  
are just finalising the details with our bean counters at the moment.


In addition to that I would like to make a suggestion as to maybe  
adding to the memories of the event beyond the ritual wearing of the t- 
shirt upon returning to our home establishments.


The consumption of hot beverages I suspect is an almost universal  
trait of the code4liber as we try to get the latest bit of perl,  
python, ruby, html, or javascript to behave as we intended it.   
Wouldn't it be nice in those occasional dark and testing times to have  
a warm and comforting physical reminder that we are part of a global  
community of similar folks, focused on and passionate about technology  
 libraries.


So...

How about a Code4lib mug or similar beverage container.  Subject to  
the featuring of a simple Talis logo, we would be prepared to explore  
the possibility of funding the production of a Code4lib 2009 mug for  
every attendee, which could feature graphics such as the winning t- 
shirt design a Code4lib message, or logo if we have one in time.


Just a suggestion - what do folks think?

Richard Wallis, Talis.

Re: [CODE4LIB] Video encoding done - Mashup idea request

[Richard Wallis]

In principle that would be a better option.  In practice you need to be
really really sure that you can simply mix the two formats in to a final
output.

Mixing PC-video and camera-video successfully together has a reputation
for being difficult.  All to do with frame rates and interlacing modes
of which I have zero understanding.  The other issue being that modern
video projectors are very good at coping with having a multitude of PCs
 Macs plugged in to them,  working out the resolution etc. and
displaying a quality image.  I am sceptical of finding some video
editing software that is so forgiving.

If a mix of video and screen capture could be achieved it would be
great, but certainty of a successful result AND a fallback if it doesn't
work should be part of the plan.

  2. Two camera's so the person at the podium can be composed inside

 If I understand this, you're thinking that one camera would
 capture the speaker, and the other would capture the slide
 presentation.

 If it's possible, wouldn't it be better to put the slides
 directly into the video, rather than showing video of the

 Screen capture could give the same option for demos, right?
