Yes, I think we should be careful to leave the basic hypertext infrastructure
stuff so that it works without consumers of the doc needing to (a)
dereference schemas (b) do subPropertyOf reasoning. So yes, decorating the
thing pointed to with additioanl properties seems a better design. It all
makes for greater expressivity: we can add several different properties,
types etc depending on scenario, without raising implementation costs for
So, I'm totally sold on something like foaf:FOAFDocument as a class, where
it is a subClassOf the much more generic foaf:Document, restricted in that
it is a 'FOAF document', ie. an RDF(/XML) document that typically uses the
FOAF RDF vocabulary.
It's the relationship between these and people that seems to require
more thought. Eikeon asked why I wanted to assert that such a
relationship should imply some authorship or control of the FOAF doc by
the person. I guess the main answer is: to make this something distinctly
more valuable than a 'meer' seeAlso.
Ah maybe this is the issue?: my own FOAF files all include stuff like
<!-- blah blah etc -->
...ie. i take care to assert that I'm described by each of my .rdf FOAF
files, even within those files. So for me it is relatively easy to
list all the (FOAF, if we add the new type) files that are about me.
Am I the only one seeAlso'ing my own files?
