This makes it sound like the support is something that will be offered in the future. I think things have progressed a little further than this simply being a design goal? As far as I understand OWL1.1 does support this in the form of Axiom Annotation http://www.webont.org/owl/1.1/owl_specification.html#A I just did a quick experiment with the OWLAPI and it seems I can write out OWLXML: <SubClassOf> <Annotation annotationURI="&rdfs;comment"> <Constant>true the last time I checked</Constant> </Annotation> <OWLClass URI="&tax;Human"/> <OWLClass URI="&tax;Animal"/> </SubClassOf> Seems to also work with functionalsyntax: EntityAnnotation(OWLClass(<http://purl.org/obo/owl/tax#Human>) Label ("tax:Human")) SubClassOf(Annotation(<&rdfs;comment> "true last time I checked") <http://purl.org/obo/owl/tax#Human> <http://purl.org/obo/ owl/tax#Animal>) The only controversial part would appear to be the RDF-XML transform: <owl:Class rdf:about="&tax;Human"> <rdfs:label>tax:Human</rdfs:label> </owl:Class> <rdf:Description> <rdf:type rdf:resource="&owl11;Axiom"/> <rdf:subject rdf:resource="&tax;Human"/> <rdf:predicate rdf:resource="&rdfs;subClassOf"/> <rdf:object rdf:resource="&tax;Animal"/> <rdfs:comment >true last time I checked</null:comment> </rdf:Description> Curiously, the OWLAPI seems to drop the actual rdfs:subClassOf triple, retaining only its reification. I'm guessing this is a bug and not a feature. The last time rdf-reification was brought up on this list it was shot down - but it seems that no alternate solutions are being considered? I personally don't have any issues with reification. There was an issue regarding multi-triple axioms: http://www.w3.org/2007/OWL/tracker/issues/12 http://lists.w3.org/Archives/Public/public-owl-dev/2007AprJun/0036.html A solution was proposed here: http://lists.w3.org/Archives/Public/public-owl-wg/2007Dec/0158.html This is still marked open, so I don't know if this is all to be regarded as finalized See also: http://semantic.nodix.net/2005/11/annotating-axioms-in-owl.html http://www.w3.org/2007/OWL/wiki/Annotation_System > -Alan > > On Feb 6, 2008, at 12:40 PM, Chuming Chen wrote: > >> >> Dear All, >> >> Given an axiom in OWL functional syntax "SubClassOf(Human, >> Animal)", how can I add annotation for it? >> >> For example, I want to add the following annotations: >> 1) add comment "Humans are animal" >> 2) add "John created this axiom" >> 3) add "This axiom was created on Feb. 6, 2008" >> >> Can anybody show me how to do this in OWL functional syntax? >> >> Thanks, >> >> Chuming >> > > >
