The Common Warehouse Metamodel (CWM) is a standard by the Object Management Group (OMG). The intention of CWM is to define a standard for metadata in Data Warehouses and Business Intelligence applications.
My intention was to learn about CWM and it is very difficult to learn a data model by studying the specifications on paper. I wanted an interactive editor. But i did not find an open source editor in the net. I found a MOF complient database, the Metadata Repository (MDR), but it does not have an editor.
So i decided to transform the CWM/MOF model to EMF and generate an editor from it.
