AbstractOMG's Common Warehouse Metamodel (CWM) is a standard modeling language for designing data warehouse systems. Nevertheless, it provides mainly syntactic metadata for either technical or business domain while it lacks metadata reasoning approach to enable metadata computation required by modern data warehouses. This study proposes a framework to represent and reason with semantic metadata in order to capture major data warehouse behaviors. These behaviors can be implicitly employed to manipulate syntactic metadata in certain circumstances. This framework seamlessly works for CWM compliance tools as well as proprietary ones mostly found in present data warehouse solutions where tools cannot be selected from a single vendor. By employing XML Declarative Description (XDD) as data representation and Equivalent Transformation (ET) as inference mechanism, the proposed framework can process CWM models represented in XML Metadata Interchange (XMI) format and derive new models resulting in appropriate configurations and dynamic system behaviors. In order to demonstrate the effectiveness of the proposed framework, a prototype system has been developed. This system can be applied to various data warehouse behaviors. In this study, development of data warehousing using prototype approach is selected as a case study in order to show the mechanism of the framework.
