[rdfweb-dev] seeAlso's for FoaF documents

[Morten Frederiksen]

Hi all,

Earlier today there was some discussion [1] on the #foaf channel about 
authorative sources of foaf data, about identification of persons and about 
helping people find seeAlso URL's.

We ended up agreeing that it would be nice to be able to qualify the 
seeAlso's that are used to point at (other) peoples foaf documents, in the 
same way that one can use rss:channel.

We found that a new class in the foaf namespace would be nice, one that 
indicated foaf content, and a property that could be used to indicate a 
primary foaf document for a person, i.e. one that suggests a good URL for use 
as a seeAlso for a person.

Daniel Krech has put up a draft of the "new" class and property [2].

* foaf:Document rdf:type rdfs:Class.

The Document class is already in the schema and in use, although it seems [3] 
to be used mostly for RDF/XML already (as is the case for seeAlso). Another 
(new) name would probably be better, but on the other hand a Document class 
in the foaf namespace should perhaps be more specific than just "a document".

* foaf:isDefinedBy rdf:type rdf:Property.

The isDefinedBy property takes its name from the rdfs one (a subPropertyOf 
seeAlso), but the schema states that it """Indicates a resource containing 
and defining the subject resource.""" which seems a bit too much for this 
purpose. So, for lack of a better name (confusion will probably arise) this 
is suggested.

Suggestions on improvements of any kind, also regarding relationships to 
other classes/properties (subPropertyOf etc.) are much appreciated.
