Ontology

REO

Roll Edition Ontology

A small extension of CIDOC CRM and LRMoo for digital editions of piano rolls. It adds the symbols a reproducing piano reads from a roll (notes and expression commands), the relations between such symbols that an editor states, and the edits by which one version of a roll becomes another. Everything else (physical copies and their holes, recording processes, versions, editorial beliefs) is expressed with CIDOC CRM, LRMoo and CRMinf directly. The closed value lists of the format are the types at https://w3id.org/reo/type/.
