Michael,

I don't know if I already suggested this to you on the HCLS list, but 
please consider adding some of the following relations to this ontology 
so that its becomes easier to explore using Linked Data's 
follow-your-nose pattern via existing Linked Data browsers:

1. rdfs:isDefinedBy
2. wdrs:describedby .

Here's how I've applied the relations outlined above to my local 
instance of your ontology, using SPARQL 1.1:

## SPARQL ##

## Ontology URI  http://purl.org/healthcarevocab/v1#
## Ontology Description Document URL: http://purl.org/healthcarevocab/v1

LOAD <http://purl.org/healthcarevocab/v1> ;

INSERT
{GRAPH <http://purl.org/healthcarevocab/v1>
        {
             ?s rdfs:isDefinedBy <http://purl.org/healthcarevocab/v1#> .
             <http://purl.org/healthcarevocab/v1#> 
<http://open.vocab.org/terms/defines> ?s.
             <http://purl.org/healthcarevocab/v1#> a owl:Ontology .
             ?s <http://www.w3.org/2007/05/powder-s#describedby> 
<http://purl.org/healthcarevocab/v1> .
             <http://purl.org/healthcarevocab/v1> 
<http://open.vocab.org/terms/describes> ?s .
         }
}
WHERE
{GRAPH <http://purl.org/healthcarevocab/v1>
         {
             {?s rdfs:subClassOf ?o}
             UNION
             {?s rdfs:subPropertyOf ?o}
             UNION
             {?s owl:equivalentClass ?o}
             UNION
             {?s owl:equivalentProperty ?o}
             UNION
             {?s a ?o}
         }
  }

## SPARQL End ###
