A question from Michael Steidl of the International Press Telecommunications Council (IPTC)... -------- Original Message -------- Subject: How to deal with an link applied to a person's name Date: Wed, 12 Oct 2011 09:23:25 +0200 From: Michael Steidl (IPTC) <mdirector@iptc.org> Organization: IPTC To: <public-rdfa-wg-request@w3.org> CC: 'Manu Sporny' <msporny@digitalbazaar.com> Hi Manu and all: We at the IPTC are currently behind making rNews 1.0 specifications and documentation public and this includes working on use cases. One specific issue is causing us some headaches: We have a web page which shows a photo and provides some metadata about that photo on that page – example: http://www.embeddedmetadata.org/test1/img-2011-10-11T084203-139.html (this is part of another IPTC WG’s project) On that page we have the name of the photographer and the metadata in the image may provide a URL in a field named “Contact information: web address” and this web address should be applied as link to the person’s name - and we want to mark this up using the rNews schema and RDFa syntax. This resulted into this HTML: <p>This picture was taken by <span rel="rnews:creator"> <span typeof="rnews:Person"><a target="_blank" href="http://www.riecks.com/ <view-source:http://www.riecks.com/>"><span property="rnews:name">David Riecks</span></a></span> </span>.....</p> When we apply this page to the RDF distiller of Kellogg Associates (http://rdf.kellogg-assoc.com/distiller) we get this result (extract only): .... <http://www.riecks.com/> rnews:name "David Riecks" . .... <http://www.embeddedmetadata.org/supportgallery-img/images/img-2011-10-11T084203-139.jpg> a rnews:ImageObject; rnews:creator [ a rnews:Person]; .... We infer from that: if a link is put around a string which is attributed as the name of a Person the RDF distiller assumes that this <a> tag provides an identifier for this person by it @href. Other people of our Semantic Web WG told me that they have the same experience with other RDF parsers. But: it is quite common to apply a link pointing to the web site of a company a person is working for to the name of a person on a web page. Therefore we assume not being the only one running into this problem. Our questions are: - Are we wrong in applying RDFa this way? – what would be the right way? - Is the distiller wrong in making this assumption? - Is there a way by RDFa means to tell the RDF distiller **not** to make this assumption? Thanks for any help in resolving this issue.
