	Resource Description Framework (RDF)
	Model and Syntax Specification
	W3C Recommendation 22 February 1999
	http://www.w3.org/TR/1999/REC-rdf-syntax-19990222/#transport

	"The recommended technique for embedding RDF expressions in an
	HTML document is simply to insert the RDF in-line as shown in
	Example 7.7. This will make the resulting document
	non-conformant to HTML specifications up to and including HTML
	4.0 but the W3C expects that the HTML specification will evolve
	to support this."


Ten years ago this week there was a PICS-NG/XML "requirements discovery" 
meeting within W3C. Members of the Consortium can read the report from 
Jon Bosak at
http://lists.w3.org/Archives/Member/w3c-labels-WG/1997AprJun/0017.html
...position papers for the meeting included the PICS-NG s-expression 
syntax, and a draft exploring possible designs for a namespaces 
mechanism in the then-unfinished XML specification.

Ten years ago last month, W3C published the last in the PICS series,
http://www.w3.org/TR/NOTE-pics-ng-metadata ... before RDF emerged from 
this rich mix of ideas (PICS-NG, MCF, XML namespaces, XML-Data, ...)  in 
more or less its current form, ie.
http://www.w3.org/TR/WD-rdf-syntax-971002/ ... circulated in October 
1997 and first presented at the Dublin Core metadata conference in Helsinki.

Time flies, eh? It really is time we got to a real 1.0 milestone for 
embedding RDF in HTML. In another decade everyone will have flying 
hovercars powered by magnets, or be uploading their brains to the 'net 
(using SOAP 1.3). But in the meantime, it would be nice to have a 
stopgap W3C recommendation for how to put structured data inside 
documents. Maybe Oct 2007 could be a fitting deadline of some kind? I 
fear 10 years become 12, ... 12 becoming 13, ...

No disrespect intended to all those working so hard on RDFa. I wish I 
had more time to help, and will continue to do what I can. But ... 
looking back on that timeline is kinda scary.
