OK, I fixed those in v 1.6 2007/01/15 18:45:41 http://www.w3.org/2001/sw/grddl-wg/td/testft.py http://homer.w3.org:8123/?cs=b8dc6c6a3cc4 > * assertedBy: make sure that dan:dwc is a foaf:Agent (such as > foaf:Person) or an earl:Software as described in [1]. Hmm... I believe I am a foaf:Agent; does EARL require that I say so explicitly? In the same file? That's odd. I already say I'm a person elsewhere. The spec seems to say that the range of assertedBy is earl:Assertor; isn't that enough? Hmm... Asserter has "allowable types" SingleAssertor and CompoundAssertor. The prose seems to say that every Asserter is either a SingleAssertor or a CompoundAssertor; you can say that using OWL: earl:Asserter owl:unionOf (earl:SingleAssertor earl:CompoundAssertor). In fact, those tables in Appendix B are pretty nice; they're just a few lines of XSLT away from being nice RDFS/OWL schemas. Why are they non-normative? When you say "required properties," do you mean owl:minCardinality 1? Looking at [1], I see "An Assertion must have at least the following properties" that's odd too. [[ I think it's a misuse of RFC2119 to say things like "2 + 2 MUST be 4" or "every attribute value in an XML document MUST be quoted." Better to just say "2 + 2 is 4" and "every attribute value in an XML document is quoted." ]] -- "must is for agents", Dan Connolly, Jan 2001 http://www.w3.org/2001/01/mp23 > [1] <http://www.w3.org/TR/2006/WD-EARL10-Schema-20060927/#assertor> > > -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
