When classifying benefits of metadata publishing two groups are usually considered. External parties are usually consumers of information that are not part of the publishing organization. Internal parties are usually the various business units or departments within an organization.
Benefits to external parties • Allows external systems (both people and agents) to have a clear understanding of the
semantics of
data elements in a system • Allows third parties to build
semantic maps between
data models and import and export data between systems • Promotes
service oriented architectures and allow horizontal sharing of information between traditional
information silos • Allows systems to participate in accurately indexed and
federated search processes
Benefits to internal parties • allows parties from diverse business units to agree on shared data definitions and separate department or function specific definitions • makes
Extract, transform, load (ETL) operations more precise for data warehousing • allows user interface designers to access a common pool of screen and report header labels • promotion of
