Abstract

Interchanging metadata between software components of a data warehouse environment is the foundation for leveraging the various benefits of an integrated metadata management for data warehousing. Besides a common understanding of metadata syntax and semantics, both a standard interchange language and an interchange mechanism for metadata are needed. We therefore propose a software architecture for metadata interchange that incorporates a shared metamodel to agree on metadata syntax and semantics, XML as a standard interchange language, and XML Metadata Interchange (XMI) as a standard interchange mechanism.
