Now all these are going to be inferred to be of type http://iptc.org/std/rNews/2011-02-02#Tag.   This will give an inconsistent ontology when someone does the sensible things and says a location and an person are disjoint from tags.

And I thought a tag is a small, flat, metal thing on a dog collar…

rnews:Tag doesn't have to be the same as michael:Tag. That's why we name things with URIs.

If it is useful *for some application* to declare rnews:Organization owl:equivalentClass ex:Organization in their own local application-specific ontology mapping, then ex:Organization and rnews:Tag are not disjoint *in that mapping*. That's fine. All mappings are wrong, but some are useful.

The Web will never be globally consistent and you know that.

Best,
Richard

IPTC seeks to develop rNews, a recently proposed practice for marking news using RDFa, which allows HTML authors to tag webpage content with indicators that browsers and tools can interpret. The standards will be compliant with NewsMLG2, IPTC’s XML format for multimedia news packages.

> IPTC’s Semantic Web Working Group is leading the charge to craft these standards. The group is mapping out the specifications essential to rNews for IPTC, and will offer examples of the standards in use, best practices for implementation, and online tools to ease the transition to the new standards. This work is set to conclude in the summer of 2011, and will better enable search engines to cull NewsML-G2 data from the Internet, ready for Semantic Web and Linked Data mining technologies.
