There are still things that can go wrong - you confirm that below when you
propose to draft a mapping and post that as N3-Draft on the web to solicit
comments. My question is if microformats wouldn't be a good place to do just
that. It's the question if we need another site, another organisation to
develop vocabularies and/or serializations in a community-process or if, at
least if a proposal with a microformats-syntax is already active, can add a
RDFa-serialization project to it?

If I want to use several vocabularies in one page, how would a GRDDL-profile
of a microformat help with conflicting microformats and the lack of
namespaces on that page in the first place?

I don't see why it needs to be seperate. I would understand, although not
necessarily agree, if "the" microformats-people said: "It's not just the
process and it's not just the serialization either - it's both together".
I'd like to discuss that.

That's a start of an Ontology 101 - not sure how that would help with my

Not so fast, please ;-) You would have to explain why you think a seperate
place for RDFa-serializations is necessary. Because microformats-people
don't want to be bothered with RDF-issues? That might be a reason but nobody
has actually raised it so far.
