RESO Data Dictionary
The RESO Data Dictionary is the Real Estate Standards Organization’s field-level vocabulary for property data — the shared nouns of American residential real estate. It defines resources including Property, Member, Office, Media and OpenHouse, along with their fields, enumerations and lookups. It is the semantic half of the RESO standard, separable from the RESO Web API that transports it, and it is the half that most industries never manage to agree on.
