Mark, A couple of clarifications as there is an important subtlety in what you wrote.

"Paving the cow paths" refers to examining existing publishing behavior by analyzing loads of websites and standardizing a markup mechanism for that publishing behavior. While it is true that the uF community attempts to not re-invent the wheel as much as we can (such as in the case of hCard, and hCalendar), there are certain cases where a new vocabulary was created. For example, XFN, hAudio, hReview, VoteLinks and hResume are examples of Microformats that did not have an "upstream vocabulary", but rather, heavily re-used concepts from other vocabularies. The bulk of the Microformats Process[1] deals with how you go about creating new vocabularies, so I don't think it's quite accurate to say that the "semantics are invariably gained by looking elsewhere" in Microformats. > It was not intended as a way to create vocabularies, but rather a > way to easily document compact formats that authors could easily grok. This is the subtlety I wanted to address. While Microformats may have started there, it's become much more than that. IMHO, the community-based process for creating vocabularies is the fundamental contribution the Microformats community is making to the semantic web. -- manu [1] http://microformats.org/wiki/process -- Manu Sporny President/CEO - Digital Bazaar, Inc. blog: RDFa Basics in 8 minutes (video) http://blog.digitalbazaar.com/2008/01/07/rdfa-basics/
