Yes, there are. Lots of them.
Please look around before you jump to conclusions and spread
misinformation.

A few lines down in
http://iandavis.com/blog/2005/10/introducing-embedded-rdf
you'll see...

[[
There is also an RDF extraction service that scans an XHTML document for
Embedded RDF and generates RDF/XML from it

http://research.talis.com/2005/erdf/extract

]]

And running code for eRDF has been discussed in this forum a number
of times; e.g. 19 Oct 2005
http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2005Oct/0041


Every eRDF document is a GRDDL document; i.e. every GRDDL consumer
consumes eRDF just fine.

Reltag is just using "tag" as a link relationship name. I'm
not sure what "specific to Microformats" means.

Nicely is in the eye of the beholder.

rel="tag" is certainly simpler than RDFa or eRDF or GRDDL or any
of the other markup idioms in this space and it's pretty widely
deployed. I don't look forward to trying to change author habits
for that sort of thing.
