I didn't know you had been in touch with the IPTC, that's great news. In a
talk on schema extensibility that I did at XML 2005, I used NITF as an
example of a very un-extensible schema. I don't know where any
microformat/RDFa approaches would fit. But, because most elements can have
an ID attribute, we can reference individual elements from triples outside
of the document, thereby adding metadata to them.
