Re: Are there any datasets about companies? ( DBpedia Open Data Initiative)

[Sebastian Hellmann]

Hi Chris,

However, making sense of this data is very, very time consuming, not 
to mentioned writing and maintaining bots  (we now have hundreds and 
hundreds of them) to scrape jurisdictions that aren't open data (the 
vast majority) takes significant resources, and we don't see any way 
of sustaining this on a CC-BY licence. 

a) is the code for these bots somewhere?
b) we hope to find a way to maintain it this time. DBpedia has received 
funding via http://smartdataweb.de/ and also http://aligned-project.eu/
We are also currently  working on a charter for an non-profit 
association that is committed to keep all data open under cc-by (we are 
accepting donations, membership fees among other things)


I could also write a book about corporate identifiers, and the issues 
with those on the list (but don't have time).

We are writing such a book* in parallel, do you want to help?

Thanks for cc'ing me. We'd had contact from Sebastian and given him an 
API key. The main issues here are sustainability and domain knowledge. 
We'd love more people to be downloading the open datasets from the UK 
and others, and using them in all sorts of innovative ways, and the 
main reason we do the Open Company Data Index 
, is to motivate company 
registers to opening up their data (I was speaking at the Open Govt 
Partnership Summit in Mexico City last week on the same subject).

Finally, there are very few registers that are CC-BY licences or less 
(for example Denmark places restrictions on use for marketing), even 
ignoring DPA issues (we are now spending a considerable amount on 
legal fees on this issue). I could also write a book about corporate 
identifiers, and the issues with those on the list (but don't have time).


So, we'd love to see more activity in the area, particularly in 
Germany – where the Handelsregister and Bundesanzeiger are very 
definitely not open data  ;-)

Brian,

When will there be any combination of the following, from this data space:

[1] SPARQL Endpoint
[2] Data Dump in one or more of the standard RDF document formats?

Working through an API is too constraining, hence the need for the
additional flexibility provided by the items above.

Hi Jason,

Well, it’s not an overlap, is more a complement. The media types described in 
such dataset (class dcterms:MediaType) are possible formats that media objects 
may have. This can be specified by means of dcterms:format property, for 
instance:

:my-video a schema:MediaObject ;
dcterms:format  .

I know it and I’ve already used it indeed for another project.

That’s a good point, and I’ve just finished to update everything, since it was 
possible in a relatively short time :-) 

In particular, I’ve just made a request to w3id.org  for a 
space, and I’ve updated le URLs of all the entities. Now they are accessible 
using the

https://w3id.org/spar/mediatype/[mediatype] 
 

e.g.

https://w3id.org/spar/mediatype/text/turtle 


Does it sound good?

Have a nice day :-)

Re: New LOD dataset for media types

FYI: The process for using the W3C's permanent identifier/PURL service is
here in the readme: https://github.com/perma-id/w3id.org

As Jeff mentioned PURL.org still works in read-only mode, you just can't
login and edit or add new PURLS right now.

RE: New LOD dataset for media types

[Young,Jeff (OR)]

The SOLR indexing on purl.org has been misbehaving for a couple of months. 
Login has been disabled for a few weeks to minimize the damage. The service is 
still running, but in read-only mode. There is no estimate for when this will 
be resolved.

One alternative is to use the http://w3id.org/ service, which is run by the W3C 
Permanent Identifier Community Group. Their mechanism is simpler and has a 
broader base of support.

Re: New LOD dataset for media types

[Haag, Jason]

Silvio,

Thanks for this work on ontologies for media types. Is there any overlap
here with https://schema.org/MediaObject ?

BTW, the W3C has a really nice process in place for IRI persistence.
Perhaps establish something like https://w3id.org/sparontologies/mediatype/
and redirect for your server. I believe you could have stronger adoption
and use of your ontology if you adopt a good IRI design and persistence
strategy up front.

There are several nice things about the W3C permanent identifier approach.
For example:

1) longevity of the IRI (if sparontologies.net ceased to exist for whatever
reason, the ontologies could be maintained elsewhere by updating the w3id
target URL/redirect.

2) You don't have to worry about configuring a server for content
negotiation. The w3id.org server is already set up to handle content neg
using apache.

3) It uses github to sync with the w3id.org server and has a strong
commitment from several folks from the W3C and other organizations heavily
invested in the web. You simply add your .htaccess files and submit a pull
request. PURL.org is current disabled and not allowing even existing users
to login and manage their PURLs. The interface and approach for PURL.org is
cumbersome.


Regards,

J Haag

They are accessible by content negotiation indeed. In particular, one can use:
- "application/rdf+xml" for having the data in RDF/XML;
- "text/turtle” or "text/n3" for having the data in Turtle;
- "application/ld+json" or "application/json" for having the data in JSON-LD;
- any other kind of request will result in having the data in HTML.

E.g.:

> curl -L -H "Accept: application/rdf+xml"

will return the RDF/XML representation of such media type.

That’s right, you can access directly to the related formats by adding .rdf, 
.ttl, .json and .html respectively. I’ll add a note in the homepage of the 
dataset and in each HTML page of each mime type soon.

Well, actually now the sparontologies.net  website 
is handled by me, with personal resources. I would like to keep it available 
without external funds, but in case it will be more expensive to maintain I 
think I can ask for support to the University of Bologna, that’s the plan at 
least. Do you have something different in mind?

That’s right, I have to add these data into the RDF representation as well – in 
my todo list.

Have a nice day :-)

Re: New LOD dataset for media types

[Graham Klyne]

Hi Silvio,

Nice work: this could be handy.  I have a couple of questions/comments:

1. I assume the machine formats are accessible by content negotiation?  It might 
be handy to also include direct links on the web page.  For example, I found I 
could change the .html suffix to .ttl or .json to get alternative 
representations, but that required guesswork on my part.


2. Are there any plans (and resources) in place to ensure longevity of the 
sparontologies.net domain?


3. I note that the HTML page indicates cc-by licensing of the content, but there 
is no such information in the machine readable formats.

Dear friends,

We are pleased to announce a new LOD dataset

http://www.sparontologies.net/mediatype

that makes available media types defined as proper resources in RDF, according 
to the SPAR Ontologies [1] and DCTerms [2].

A media type is an identifier (for example "text/turtle") for file formats on the Internet composed 
by two parts: a registry ("text" in the example) and a record ("turtle" in the example). 
They are handled by the Internet Assigned Numbers Authority (IANA), which is the official authority for the 
standardisation and publication of these classifications.

The aforementioned web space, part of the SPAR Ontologies website, has been reserved for providing the RDF 
representation of each media type defined by IANA [3]. In particular, a media type is accessible by 
concatenating the URL "http://www.sparontologies.net/mediatype/"; with its related identifier. For 
instance, "http://www.sparontologies.net/mediatype/text/turtle"; allows one to access the specific 
resource for the "text/turtle" media type.

Each media type can be accompanied by agents who acted as contributors, the 
related RFC documents documenting it, its current status (either official, 
deprecated or obsoleted), and direct links to Wikipedia pages and DBpedia 
resources related with the media type.

All these resources defining media types, thus, can be used for specifying 
particular formats (e.g., by means of the DCTerms property dcterms:format) that 
a certain entity, such as a book or a dataset, can have.

Please do not hesitate to contact us (sparontolog...@gmail.com) for questions 
and additional information about this LOD dataset.

Have a nice day :-)
