Linked Data and the Guardian
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

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.

Travel ontology/vocabulary
Hi Everybody 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. Thanks! Juan Sequeda +1-575-SEQ-UEDA www.juansequeda.com
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.

Re: Linked Data Movie Quiz
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.

Re: XRI and XDI
FWIW, the Oasis page http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=xdi has this on it: The XDI TC has developed a new RDF based model... which suggests that it now is not being proposed as an alternative to RDF, anyway.
