Description:
RDFa Core 1.1 Last Call comments from Ian Hickson:

I believe RDFa should not have prefix-based indirection, for reasons that
have been listed many times over the past few years; since this draft adds
two new indirection mechanisms rather than removing any, I am not
satisfied that my earlier feedback has been adequately addressed.

The permitted use of xmlns="" as one of the prefix declaration mechanisms
specifically will cause serious compatibility issues for reasons that have
similiarly been elucidated numerous times over the past few years.

The language as a whole is overly complicated, e.g. with a preponderance
of attributes significantly beyond the minimum necessary. Again, this
issue has been described in detail in the past.

IMHO, you should do some real usability studies (one-way glass and
everything) like we did with microdata. Or at a minimum, see if people
outside the RDF/RDFa community can actually use RDFa for any non-trivial
purpose without help and actually get it right. Or indeed, the same with
implementators. So far, every implementor I'm aware of has done it with
fundamental bugs in their first attempt. Some have since fixed those bugs,
but any technology can be implemented correctly _eventually_ -- whether
the bugs get shaken out after years of work isn't the interesting
question. What matters if you want long-term interop is whether someone
you've never heard of can implement the technology more or less correctly
the first time, without being pestered into fixing problems.
