Interesting stuff there. To me especially as I studied languages in school, and have always been fascinated by the roots of words, and how they relate to other languages or cultures. Do you have <a href="https://launchpad.net/openclipart">Launchpad </a>access? May I suggest you add that as a Blueprint for OCAL? I don't know enough about tags to comment on the technical side of tags, as you outlined below, but I believe in OCAL being accessible to everyone. I do know at the moment we are focusing on getting the (only) English version ready. Perhaps we can extend into other languages as well, later in the future. That would be cool. :) <div class="gmail_quote">On Thu, May 14, 2009 at 2:02 PM, Francis Bond <<a href="mailto:fcbond@gmail.com">fcbond@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div><div class="h5"> </div></div>I would like to suggest adding a language tag to the keword metatag, either explicitly within the tag (for cat): <dc:subject> <rdf:Bag> <rdf:li lang='en'>mammal</rdf:li> <rdf:li>feline</rdf:li> </rdf:Bag> or implicitly in the text: <rdf:li>en:mammal</rdf:li> then we could include different language tags within the actual images. I would also like to add the opportunity to add more semantic webby tags. In particular, I have tagged some pictures from v0.18 to WordNet: <a href="http://nlpwww.nict.go.jp/wn-ja/eng/pics.html" target="_blank">http://nlpwww.nict.go.jp/wn-ja/eng/pics.html</a> These links are all in the public domain. If we link a picture of "dog" to, for example, wn-eng-02084071-n, then this allows us to look it up in many ways: <rdf:li type="wn">wn-eng-02084071-n</rdf:li> <a href="http://nlpwww.nict.go.jp/wn-ja/cgi/wn-synset.cgi?synset=02084071-n" target="_blank">http://nlpwww.nict.go.jp/wn-ja/cgi/wn-synset.cgi?synset=02084071-n</a> (a) hypernym search --- I look for "terrier", can't find a picture then we and offer an image of its hypernym and get a picture of a dog. (b) hyponym search --- I look for "carnivore", can't find a picture and show pictures of its hyponyms: dogs, wolves, foxes, lions, (c) crosslingual search (which is my main interest) English WordNet is linked to free wordnets in Japanese, French, Spanish, Catalan, Arabic, ... so we could look up 犬 in Japanese and find the picture of a dog. If anyone is interested in this, please contact me. I am keen to work on it from the WordNet side, but don't want to learn PHP :-), as I am a PERL man. There are already some libraries for WordNet and PHP: <a href="http://wordnet.princeton.edu/links#PHP" target="_blank">http://wordnet.princeton.edu/links#PHP</a>. -- Francis Bond <<a href="http://www2.nict.go.jp/x/x161/en/member/bond/" target="_blank">http://www2.nict.go.jp/x/x161/en/member/bond/</a>> NICT Language Infrastructure Group </blockquote></div> -- Cheers Chovynz
