Concept mapping
A link from a term to a concept in another vocabulary, as an exact, close, broad, narrow or related match.
A term lists its mappings in exact-matches, close-matches,
broad-matches, narrow-matches and related-matches. Each becomes the
SKOS mapping property of that kind. manni term check reports an IRI listed
under two kinds, and manni graph check reports a mapping that points into
the scheme itself. See Check rules.
