Oracle Enterprise Metadata Manager

The Oracle Enterprise Metadata Manager (EMM) is a product of the Oracle Corporation that provides an ISO/IEC 11179 metadata registry.

Strategic nature of a metadata registry
This product is significant because it is one of the first commercial products that includes a metadata registry in an application server. Registering metadata is one of the first steps in metadata publishing which in turn is one of the foundational elements of the Semantic Web.
