Pat and Kingsley and others who responded,
Sorry for taking so long to reply (but work got in the way). I just updated the reusable metadata ontology on the GitHub site (http://purl.org/ninepts/metadata). As documented before, click on the version of the ontology that you want (functional syntax, rdf/xml or turtle) and get the "Raw" version for import into Protege or a triple store (or whatever).
One (hopefully interesting) addition that I made is a new property, competencyQuestions, for the ontology. I also defined a competencyQuery property. The latter is a SPARQL query that could be executed to validate the ontology. There is one competencyQuery for each competency question. (The queries are not very interesting for the metadata-annotations ontology, since it is just a bunch of annotation properties, but the overall approach seems valuable.)
Now, back to the replies ...
Pat said ... "One should always re-use existing (and widely deployed) IRIs where possible. If you want your ontology to actually be used, that is."
I updated the IRIs for the contributor, coverage, creator, date, description, language, relation and rights properties to use the DC IRIs, and for the *Label, note and *Note properties to use the SKOS IRIs. I did not change the IRIs for the mappingRelations (since my properties were a bit different in definition and naming).
Pat also said ... "You can use the DC and SKOS IRIs without actually importing the RDFs, so you only use the ones you need. Importation is a red herring here."
You are right. I just used the IRIs where the properties did match up. I did not import the full RDFs.
Kingsley said ... "my concern boils down to not seeing labels and comments as part of the entity descriptions in the RDF document I looked at. Maybe you can provide a sample entity URI for me to investigate further."
I think that I addressed this in the new ontologies that were loaded. You should now see prefLabels and descriptions for everything, scopeNotes for most properties, and comments for some properties.
