I just don't buy his argument, for a couple of reasons. First, his
assertion that XML is everywhere and SGML is nowhere could also be
reformulated as SGML is everywhere because XML is everywhere (XML being a
subset of SGML). But the primary reason I disagree is that, while
Microdata may overtake RDFa for making semantic assertions in HTML, this
is still only a little bit of the big picture. RDF is a data model that is
serializable in multiple ways (Turtle, RDF/XML, RDFa) for use in multiple
contexts. Microdata can be embedded only in HTML at this point.
On a side note, I would be very happy to see a mechanism for RDF (perhaps
RDFa?) in TEI. Overjoyed even.
