Alignment of SSN and SOSA

I just created a little file containing an initial proposed mapping from SSN to SOSA and loaded it to a branch – see

https://github.com/w3c/sdw/blob/simon-ssn/ssn/rdf/ssn-sosa.ttl


I just followed the alignment shown here: https://www.w3.org/2015/spatial/wiki/Mapping_Table but expressed it more formally so all the alignments are cast as

ssn:XXX rdfs:subClassOf sosa:YYY .
ssn:vvv rdfs:subPropertyOf sosa:uuu .

except for one, which is the other way round because the definition in SOSA seemed to be more restricted than SSN.

sosa:hasValue rdfs:subPropertyOf ssn:hasValue ;
.

I think this matches the discussion today. I issued a pull-request.

In some cases it may be appropriate to replace rdfs:subClassOf with the stronger owl:equivalentClass.

This relates to ISSUE-37, ISSUE-49, ISSUE-88, ISSUE-102, ISSUE-115, ISSUE-139 .
