get-superrelations [Function]


The get-superrelations function finds all superrelations, or only the direct superrelations, of a given relation. If the argument to get-superrelations is a symbol, and no matching relation can be found, then Loom looks for a matching concept and returns the concept's supers.


get-superrelations relationOrConcept &key direct-p


The relationOrConcept argument is the relation (or concept), or the name of the relation (or concept), whose superrelations (or superconcepts) are to be found.

If the direct-p argument is t, only the most specific superrelations (or superconcepts) are returned. Otherwise, all superrelations (or superconcepts), including relationOrConcept itself, are returned.


This function returns a list of relations, or a list of concepts.
