Leo and Kingsley, Here are some replies (thanks for the dialog):
* Kingsley wrote: "... there are a lot of raw URIs in the scope of the viewer. You alleviate this problem by adding more rdfs:label, skos:prefLabel etc.. relations i.e., I would have a label and comment (at the very least) for every entity described in these documents."
There actually is a label, a description and much more for each entity. The difference is that the ontology uses its own namespace, and not the standard ones. And, I have avoided importing the Dublin Core and SKOS RDFs, because you then get all the concepts from those schemas. In a comment on the ontology, I discuss what I did not map from Dublin Core and SKOS, and why.
I was trying to make a succinct ontology that listed the "recommended" properties that should be provided for a reusable ontology. (Which also means that I will be adding more details - like documenting the competency questions for the ontology. I just started with Dublin Core and SKOS.)
Also, there are two sides to the coin of using the standard annotations. If you have a tool that reads/writes the standard properties, then all is good. However, if you are creating your own application, you have to remember when writing queries (or hand-editing ontologies, etc.) that rdfs is the prefix for label, skos is the prefix for prefLabel, etc. I was hoping to simplify this. I have some customers doing their own ontologies that get confused by all the namespaces.

Unfortunately in OWL, more complex statements of axioms do have to be put into annotations/documentation."
This was not my intent with the annotation properties. I was not trying to do alignment, but simply to document the correspondence of the concepts. As I said in my previous email, annotation properties are "obviously totally inadequate to do anything significant, but [they are] a start as a documentation tool ... Separately, I am working on a more formal approach to mapping, but starting with documentation is where I am."
Hope this helps explain things better, and thanks for the feedback.
