get_observed_terms

get_observed_terms(mappings: Iterable[Mapping]) → Mapping[str, Collection[str]][source]

Get the set of terms appearing in each prefix.

Parameters:: mappings – An iterable of mappings
Returns:: A dictionary from prefixes appearing in subjects/objects of mappings to the set local unique identifiers appearing in mappings
