No, if dan:dwc is of type foaf:Person (or any other foaf:Agent subclass) then it conforms to the spec. > The spec seems to say that the range of assertedBy is earl:Assertor; > isn't that enough?

We used owl:oneOf, also for earl:SingleAssertor.

Why are they > non-normative? To avoid having the RDF/XML and the tables be both normative. However, I grant your point and we will re-discuss this issue. > When you say "required properties," do you mean owl:minCardinality 1? Correct. > Looking at [1], I see > "An Assertion must have at least the following properties" > that's odd too. It should mean "An instance of an Assertion class must contain the following properties". Would that be a more precise way to phrase "owl:minCardinality 1" in simple text? >> [1] <http://www.w3.org/TR/2006/WD-EARL10-Schema-20060927/#assertor> Regards, Shadi -- Shadi Abou-Zahra Web Accessibility Specialist for Europe | Chair & Staff Contact for the Evaluation and Repair Tools WG | World Wide Web Consortium (W3C) http://www.w3.org/ | Web Accessibility Initiative (WAI), http://www.w3.org/WAI/ | WAI-TIES Project, http://www.w3.org/WAI/TIES/ | Evaluation and Repair Tools WG, http://www.w3.org/WAI/ER/ | 2004, Route des Lucioles - 06560, Sophia-Antipolis - France | Voice: +33(0)4 92 38 50 64 Fax: +33(0)4 92 38 78 22 |
