The RDFa API is a mandatory deliverable in the RDFa WG charter (slated
to start in Feb 2010).

If the RDFa WG is approved, this MUST be spec'ed and MUST be
REC-track... in other words - the RDFa API is definitely going to happen. :)

Right, but that doesn't mean that the RDFa community hasn't been
listening. In fact, we are taking very firm, methodical steps to address
those concerns in the RDFa WG... here are just a few of the changes that
we're planning on making during the RDFa WG work period:

* Support for full URIs in @about, @rel/@rev, @property, (no namespaces,
no prefixes) - this was something that Julian, Ian and a few others
wanted and we finally found a way to do it that was backwards compatible
and consistent.[1]

* Importing non-namespaced, non-prefixed, vocabulary terms to ease
authoring, effectively enabling every current Microformats vocabulary to
be expressed in RDFa[2]. This was raised by the
no-visible-namespaces/qnames-in-content/easy-authoring folks in WHAT WG,
RDFa TF and HTML WG.

* Implementing a different prefixing mechanism, other than xmlns:.

* Re-organizing and formulating the core RDFa specification such that
implementation in raw byte-stream, SAX, DOM and Infoset-based
environments is clarified.

So, there's a great deal of exciting work that's coming down the
pipeline for RDFa - the RDFa community is moving forward on technical
solutions - RDFa isn't going away.
