number of organisations that have implemented ebXML RIM to satisfy a requirement for an ISO/IEC 11179 registry, ebXML RIM is neither a registry nor does it store metadata. It is a "content repository" and a "metacontent catalogue". Metadata registry roles A metadata registry is frequently set up and administered by an organization's data architect or data modeling team. Data elements are frequently assigned to data stewards or data stewardship teams that are responsible for the maintenance of individual data elements through a secure system. Metadata element workflow Metadata registries frequently have a formal data element submission, approval and publishing approval process. Each data element should be accepted by a data stewardship team and reviewed before data elements are published. After publication change control processes should be used. Metadata navigation, search and publishing Metadata registries are frequently large and complex structures and require navigation, visualization and searching tools. Use of hierarchical viewing tools are frequently an essential part of a metadata registry system. Metadata publishing consists of making data element definitions and structures available to both people and other systems.
