knowsAbout

A property on a Person or Organization listing the subjects the entity claims expertise in, ideally as DefinedTerm nodes with a sameAs to a public identifier. Limited to what the site's own content evidences, it is one of the few machine-readable expertise statements; padded, it is a list of keywords nobody will believe.
