Include mappings from OMO to other vocabularies and schemes such as skos

[cmungall]

I made a start on this here:

https://github.com/INCATools/ontology-access-kit/blob/d1c4a46c3efda1779fd587d9b79f70db87bc2aa9/src/oaklib/conf/omo-to-skos.sssom.tsv

but I would rather maintain these longer term in OMO rather than in OAK

The use case here is an ontology library that supports operations like "lexical match using synonyms", "do lookup by label", "add new synonym" regardless of whether the ontology is OBO or not. See: INCATools/ontology-access-kit#315

rdfs:subClassOf	skos:exactMatch	skos:broader

could raise some eyebrows.. not really "exact", but I get what you are saying. BTW the correct "mapping justification" I think would be ManualMappingCuration - LexicalMatching is really more appropriate when a lexical matching tool was used.

My two cents: you will get a faster turn around if we curate these in OAK for now, rather than OMO - and also, do they not belong in some "general" ontology-metadata linkml model as "mappings"?
