Mapping JERM to PROV-O

[stain]

Partial fix for #2 - mapping JERM to PROV-O as upper ontology.

I have mapped with rdfs:isDefinedBy citations rather than noisy owl import.

In particular mapping classes:

• jerm:Person subclassOf prov:Person as a JERM person must be a member of at least one Project, and (for some reason) must be a contributor of some Asset
• jerm:MaterialEntity subclassOf prov:Entity
• jerm:InformationEntity subclassOf prov:Entity

And object properties:

• jerm:isDerivedFrom equivalentTo prov:wasDerivedFrom
• jerm:hasContributor subPropertyOf prov:wasAttributedTo (and thus also jerm:hasCreator)

While I was tempted, I did not add:

• jerm:Process subclassOf prov:Activity -- as jerm:Process says it hasContributor some Person -- the mapping above for hasContributor would (on OWL import of the whole PROV-O ontology) cause an inconsistency because prov:wasAttributedTo has a domain of prov:Entity, which in PROV is disjoint with prov:Activity.

I am a bit confused of what the jerm:Process hierarchy means, are they plans for processes experiments, etc. that may or may not happen, or are they something that has happened (or is already happening). I would think it should be the second, which hints that it is a prov:Activity, as defined in PROV

An activity is something that occurs over a period of time and acts upon or with entities; it may include consuming, processing, transforming, modifying, relocating, using, or generating entities. [Detailed specification] Just as entities cover a broad range of notions, activities can cover a broad range of notions: information processing activities may for example move, copy, or duplicate digital entities; physical activities can include driving a car between two locations or printing a book.

In that aspect we would then presumably also map jerm:hasInput equivalentProperty prov:used and jerm:hasOutput equivalentProperty prov:generated -- but I'm not sure here again if JERM's hasInput/hasOutput are meant to be records of something that was used/made, or linking to a (template/type) of something that could be used/made - the use of present tense here makes it very confusing.
