The following is the report and a proposal on my ACTION: Michael look for a more semantically correct predicate for tests 42-45 [recorded in http://www.w3.org/2007/09/06-rdfa-minutes.html#action14] Background: FOAF Vocabulary Specification 0.9 [1] Problem: TC42-45 use foaf:img - this is semantically wrong. Analysis: Relevant properties are + foaf:depiction [2], + foaf:depicts [3], which is the inverse of foaf:depiction, and + foaf:img [4], a sub-property of foaf:depiction foaf:depiction has owl:Thing as domain, while foaf:img has foaf:Person as domain. AFAIU there exists no inverse of foaf:img (which is IMHO not relevant to our problem, however:) Conclusion: Use foaf:depiction instead of foaf:img, as every resource is an owl:Thing, and so is the Web page. @DanB: Any objections?
