Metadata registries have also facilitated interoperability among schemas in that they record authoritative information about metadata elements from multiple sources. A metadata registry is a “…database used to organize, store, manage, and share metadata schemas. [They] provide information about metadata schemas, elements, profiles, definitions, and relationships, using a standard structure” (Taylor, 2004, p.153).
Thus, metadata registries facilitate interoperability since they provide a record of names, definitions, and properties of metadata elements. Metadata creators can consult a registry to clarify meaning and usage as well as exchange information. Additionally, metadata registries can help prevent duplication of effort (Taylor, 2004).
The Dublic Core Metadata Registry Lite is one example of a metadata registry, available at http://wip.dublincore.org/dcregistrylt/
