Metadata synchronization system

A metadata synchronization system, the metadata synchronization system comprising:

• a federated metadata repository;
• a governed metadata repository;
• a crawler;
• and
• a processor;
• the metadata synchronization system operable to:
• receive, at the federated metadata repository, a plurality of metadata elements, said plurality of metadata elements being transmitted from a plurality of applications, said plurality of applications being coupled to a plurality of application hubs;
• receive, at the governed metadata repository, a subset of the plurality of metadata elements, said subset of the plurality of metadata elements being entity-critical metadata elements, said entity-critical metadata elements comprising at least governed assets and relationships, each entity-critical metadata element including a six-part attribute key, each of said six-part attribute keys not being included in the plurality of metadata elements included in the federated metadata repository, each of said six-part attribute keys comprising a server name variable character attribute, a database/location variable character attribute, a schema name variable character attribute, a table/file name variable character attribute, a column/field name variable character attribute and an originating metadata repository number attribute;
• crawl, via the crawler, the plurality of applications, to determine that each metadata element included in the plurality of metadata elements has been received at the federated metadata repository;
• transmit a first notification message to a first user in the event that a metadata element is not received at the federated metadata repository;
• crawl, via the crawler, the federated metadata repository and the governed metadata repository to determine whether each metadata element that is included in both of the federated metadata repository and the governed metadata repository are identified using the same data type;
• upon identification of a metadata element which is identified using one data type in the federated metadata repository and another data type in the governed metadata repository, conform, via the processor, the data type of identified metadata element included in the federated metadata repository and the data type of the identified metadata element included in the governed metadata repository;
• crawl further, via the crawler, the plurality of applications to identify an extinct metadata element in an application that is coupled to the federated metadata repository;
• in response to identifying of the extinct metadata element, remove the extinct metadata element from the federated metadata repository;
• and
• conform, via the processor, the governed metadata repository to the federated metadata repository by removing further the extinct metadata element from the governed metadata repository.
