This profile is http://www.w3.org/2003/g/td/xfn-workalike. It demonstrates how XFN and GRDDL could work together.
HTML4 definition of the 'rel' attribute. Here are some additional values, each of which can be used or omitted in any combination (unless otherwise noted, and except where prohibited by law) and their meanings, symmetry, transitivity and inverse if any. Please see the XFN home page for more information about XFN.
... and so on; see the real XFN profile for the rest. (I acknowledge that the license under which the XFN profile is released does not permit derivative works; I intend for this to be fair use.)
Use of this profile licenses RDF data extracted by grokXFN.xsl.
glean.py implements GRDDL extended to peek into profile documents so that one pointer to grokXFN.xsl will work for all documents bearing the XFN profile.
This profile is connected grokXFN.xsl via a profileTransformation link.
The same idea should work for the dublin core profile etc..
