I forgot that we had RDF category indices too. There was lots of shonky stuff in there, including a non-existent "gs:" (oops, dated...) namespace for most of the stuff. So I worked it over too.
Before: http://london.openguides.org/index.cgi?action=index;index_type=category;inde...
After: http://un.earth.li/~earle/cgi-bin/wiki.cgi?action=index;format=rdf
Looks good. Is there any way we can get the list of categories for a page into the RDF? This would be really useful for something I am attempting.
Something on the lines of:
- <og:Wiki rdf:ID="obj"> dc:titleAldgate Station</dc:title> og:CategoryTube</og:Category> og:CategoryTube Termini</og:Category> </og:Wiki>
but I'm not very well up on the semantics of RDF. In the mean time I will scrape the HTML pages with HTML::TokeParser.
Looking further into it, dc:Type and dc:Subject are both tags for categorizers.
Thoughts please.
(Examples selected for brevity of output - try using the W3C RDF validator to get diagrams of them.)
This is cool! I find links from this to places like http://dublincore.org.
Cheers,
Ivor.
