A metadata registry is an information system for registering metadata.

Within ISO/IEC International standard 11179, a metadata registry is a database of metadata that supports the functionality of registration.

Registration accomplishes three main goals: identification, provenance, and monitoring quality.

Identification is accomplished by assigning a unique identifier (within the registry) to each object registered there.

Provenance addresses the source of the metadata and the object described.

Monitoring quality ensures that the metadata does the job it is designed to do.

A metadata registry manages the semantics of data. Understanding data is fundamental to its design, harmonization, standardization, use, re-use, and interchange. The underlying model is designed to capture all the basic components of the semantics of data, independent of any application or subject matter area. Registration also allows two or more administered items describing identical objects to be identified, and it will identify situations where similar or identical names are in use for administered items that are significantly different in one or more respects.
