Metadata Repository¶
A metadata repository is a store for metadata.
Most organizations have several, and they arrive for different reasons: a database catalog that came with the database platform, a data catalog bought to support an analytics programme, a configuration management database run by the infrastructure team, a modelling tool with its own repository. Each is authoritative about part of the landscape and knows nothing about the rest.
A metadata repository that supports the open metadata standards is called an open metadata repository. Supporting those standards is what allows repositories to work together: they can exchange metadata, agree on which of them is the master of each element, and present a single view of the landscape to the people and processes that need it.
A repository that does not support the open metadata standards natively can still take part, through a repository proxy that translates the open metadata repository API into the repository's own API, or through an integration connector that keeps a catalog entry in step with it.
