Key to columns:
- Example
- An actual URI of a person. * An asterisk means there is no URI for the person themselves, only for their FOAF file.
- People
- Approximate number of people (and therefore of FOAF files) if known.
- Links out
- Yes/No. In your profile, you can enter the URI of a FOAF identity you have on 'another' site.
- OpenID Integration
- Yes/No.
- Is there a
foaf:openid value that gives the URI of the (X)HTML page used for OpenID authentication? The Inverse Functional nature of the foaf:openid property enables use of my OpenID on par with my Personal URI via an inference-capable RDF User Agent (e.g., a SPARQL Processor).
- In addition, but not mutually exclusive to the prior usage scenario, can a single URI be used as a conduit to both FOAF file and OpenID authentication page? Example: http://myopenlink.net/dataspace/person/kidehen is a URI that both provides OpenID authentication and exposes a FOAF file.
Thus, these two SPARQL statements would return the same results:
SELECT DISTINCT * WHERE { <http://myopenlink.net/dataspace/person/kidehen> ?p ?o }
and
SELECT DISTINCT * WHERE { <http://myopenlink.net/dataspace/person/kidehen#this> ?p ?o }
Sites which no longer offer FOAF, or whose FOAF is not easily discoverable
Updates welcome. I tried registering with most of these sites, to see if their FOAF was just members-only, and still found no joy.

Note: A better way to make this page would be to make it in the data wiki and mash it up here as a table.
