This data dictionary defines the metadata that will be recorded for organizations.
Some fields are repeatable, such as "Instance of", where an organization can be both a museum and an archives at the same time.
Some fields are mapped to the same Wikidata property, such as "City", "County", and "State", all of which map to "located in the administrative territorial entity".
All fields that are sourceable are followed by two additional columns for the reference URL (P854), noted as REF URL, and the date retrieved (P813), noted as RET DAT. This enables sourcing information at the individual value level. These fields are always REQUIRED when present.
