An organization of database and data warehouse vendors founded in 1995. Within a year, it introduced the Metadata Interchange Specification (MDIS) as a standard for defining meta-data. It also developed Microsoft's Open Information Model (OIM) and later merged MDIS into OIM. In 2000, the Meta Data Coalition merged with the Object Management Group (OMG). OMG has worked on integrating OIM into its Common Warehouse Model (CWM) in order to provide a single standard for modeling meta-data in data warehouses. See metadata.
