schema:alternateNamexsd:stringAn alias for the item.
schema:descriptionxsd:stringA description of the item.
schema:disambiguatingDescriptionxsd:stringA sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.
