After reading Bob's blog entry (bobdc.blog: Putting semantics on the web), I looked at the source for his page. I noticed that metadata is applied using:
<!-- <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:trackback="http://madskills.com/public/xml/rss/module/trackback/" xmlns:dc="http://purl.org/dc/elements/1.1/"> <rdf:Description rdf:about="http://www.snee.com/bobdc.blog/2006/01/putting_semantics_on_the_web.html" trackback:ping="http://www.snee.com/cgi-sys/cgiwrap/bobd/managed-mt/mt-tb.cgi/93" dc:title="Putting semantics on the web" dc:identifier="http://www.snee.com/bobdc.blog/2006/01/putting_semantics_on_the_web.html" dc:subject="semantic web" dc:description="Painlessly adding RDF-compatible semantics to XHTML." dc:creator="Bob" dc:date="2006-01-31T09:17:35-05:00" /> </rdf:RDF> -->
I have been using the Dublin Core recommendation (http://dublincore.org/documents/dcq-html/):
Also, with the recommendation in the RDF / A Primer, a different approach is used.
Is there a single, best practice for embedding the metadata for the Semantic Web? Are the above approaches compatible?
I have since found out that Bob is using Movable Type, and that's how the metadata is generated. I'm using macros in my blogger.com template. Another approach to consider is/are Microformats.
It would be nice [HINT, HINT to all you folks creating new standards] if there was a standard, easy to use approach for adding metadata for the Semantic Web. RDF and OWL by hand is painful, just like XML Schema. I want something easier like RNC is to Schema -- just as powerful, if not more, but easier to use!
