Linked Data and the Guardian

2010-10-18 Thread Yves Raimond
Hello!

The Guardian just announced that they added ISBNs and Musicbrainz
GUIDs to their API:

http://www.guardian.co.uk/open-platform/blog/linked-data-open-platform
http://www.guardian.co.uk/open-platform/blog/references-in-api

Nice feature enabling Linked Data apps (BBC Music?) to draw in
Guardian content very easily. It is also a first step in the Linked
Data world from the Guardian, which is very good!

Best,
y

 Hi everybody
 I just stumbled on XRI and XDI:
 http://www.xdi.org/modules/tut3/index.php?id=2
 A quick overview of this seems that it is the same thing as Linked Data. XRI
 are identifiers (URIs) and XDI is a data interchange format (RDF)
 ...n which XML data from any data source can be identified, exchanged,
 linked, and synchronized into a machine-readable dataweb just as HTML
 pages from any content source are linked into the human-readable Web today.
 What makes this interchange format possible is identifying, describing, and
 versioning data using XRIs.
 This is the first that I've heard about this? Who know about the status of
 this? Who is adopting this?

Last I heard the W3C TAG's decision was not to take forward the
development of XRI or specs containing XRI, but rather, to explore the
use of URIs as the value proposition of the WWW [1].

Subsequently, the OASIS membership voted against it becoming a spec,
which was perhaps not received as well as it could have been, by the
folks at on the OASIS XRI committee [2].

It's currently still mentioned in some pockets still, namely some of
the OpenID specs.

The future of XRI I believe is uncertain, with some saying it has died
and saying it is alive and well [3]

However a new version, 3.0 is coming out later this year.  It is
purported to have addressed the concerns of the TAG [3]

It will be interesting to see what the new version brings, when it comes out.

 Dear LODers,

 We have created a simple webapp that generates questions about cinema by
 querying the Linked Movie DataBase ([1], many thanks to Oktie et al. for
 that project and their support).

 The so-called Linked Data Movie Quiz is available at [2], as part of a
 contest where webapps had to be developed in less than 10KB [3].

 We hope that even if simple, and not accessing but a single repository, the
 application is able to showcase the power of using available Linked Data.
 (Indeed, a huge number of questions are automatically generated with very
 little code.) Doing well in the contest proved difficult, for there were
 very nice HTML5 demos in there, but I reckon it was good in terms of Linked
 Data evangelism. :-) (I tried to write during the contest, but somehow the
 email didn't make it through.)

 There are some more details about the LDMQ in [4]. We'll be glad if you try
 it out (advice: less bugs -but still some- if you don't use IE6 or 7) and
 send some feedback.

 Cheers,
 Guillermo (and Jorge)

Travel ontology/vocabulary

Re: Travel ontology/vocabulary

Hi Juan:

Can somebody recommend me an ontology/vocabulary to describe travel,  
accommodations, etc? The only thing I can find is the travel  
ontology that is used for tutorial purposes in Protege.


For rental cars, boats, bikes, etc., the best choice is likely the VSO:

http://purl.org/vso/ns

See examples there.

For any kind of tickets for transportation and events, there will be  
the TIO ontology soon (not yet released) and for accommodation, there  
will be a hotels etc. ontology, both specializing GoodRelations. Both  
should be available shortly.
The domain ontology for hotels etc. will only be needed to model the  
hotel room features etc. in more detail.


Note that you can directly model any kind of rental offers with  
GoodRelations, using


foo:offer a gr:Offering ;
gr:hasBusinessFunction gr:LeaseOut.
...

Interesting properties for your purpose are

gr:advanceBookingRequirement (relative pre-booking period)
gr:validFrom (Booking period)
gr:validThrough
gr:availabilityEnds (Period of the stay)
gr:availabilityStarts
gr:availableAtOrFrom (link to the locations)
gr:eligibleDuration (time interval - number of days, min/max)

Here is a quick sketch of modeling a hotel in GoodRelations:

Re: Linked Data Movie Quiz

2010-10-18 Thread galvaro
Hi Ian,

We're glad you liked it. :-)

We considered using other datasets (for example, we thought geographic questions
could've been potentially interesting), and it would be indeed nice to expand
the scope of the quiz to other fields, as you suggest.

It wouldn't be so straightforward to do so out-of-the-box (in a refined version,
first of all we'd need to carry the logic to the server-side; because of the
contest rules, all the queries were done via javascript from the browser), but
we plan to upload the code to GitHub (maybe in November) and we can further
discuss from there.

Cheers!

The XDI TC has developed a new RDF based model...
