common warehouse metadata interchange (CWMI)

The data stocks stored in companies, which are stored in data warehouses and other management systems, are described by metadata.

Since the various systems describe the data differently, the Common Warehouse Metadata Interchange (CWMI) ensures standardization in the exchange of metadata. With CWMI, the metadata of different databases of a company can be managed centrally. It provides transparent access and interchangeability of data.

CWMI is based on the Extensible Markup Language(XML), the exchange format for metadata XML Metadata Interchange(XMI), the description language Unified Modeling Language( UML) and the Meta Object Facility( MOF) for distributed repositories.
