bobdc.blog: Putting semantics on the web

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:

  <!--

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!
