Hierarchical matches

[dr-shorthair]

XKOS provides xkos:ConceptAssociation to support n:m correspondences.
In the case of a 1:m or n:1 relation, it is unclear whether these would be partitive or subsumptive relations.
It would be helpful for 1:m (and n:1) associations to also be able to carry a predicate to clarify this.

XKOS provides xkos:specializes and xkos:isPartOf to clarify the hierarchical relationship skos:broader.
However, this applies within a classification, and not as part of matching relationships between classifications.
Perhaps xkos:specializesMatch and xkos:isPartOfMatch are also needed?

To be studied for V2.
This would be specializations of skos:broaderMatch or skos:narrowerMatch ?
See what Records In Contexts (RiC-O 1.0) is doing in terms of equiavlence between relation entities and their equivalent binary predicate. See looong dicussion at ICA-EGAD/RiC-O#67
