I agree with Gregg that 1 will not work. In particular, I believe it will
fail for terms created using schema.org's extension mechanism [1].

I believe that a registry is the best way to accomodate the flexibility of
microdata vocabulary specifications while also providing consistent URI
generation. I believe that this can be effectively crowd-sourced so that
vocabulary publishers don't have to go to extra effort.

While vocabulary based parsing seems an untenable solution, Richard Cyganiak
has a proposal for how 2 URI generation patterns could be defined for
vocabularies to follow; vocabulary based or itemtype based. This would allow
processors to just be coded to handle either of those two. Then the registry
could just designate which pattern a vocabulary uses. The key point
here: *Processors
would not need to be updated for vocabularies*.

Richard has done a lot of good thinking about this, so I asked him to write
it up [2]. I know it's still very much a work in progress, but I think
developing this idea further could accomodate the flexibility of microdata
without introducing inconsistency.
