The Aristotle Metadata Registry is a user-friendly metadata registry as laid out by the requirements of the ISO/IEC 11179:2013 specification. The Aristotle Metadata Registry represents a new way to manage and federate content built on and extending the principles of leading metadata registries. By allowing organisations to run their own independent registries they are able to expose authoritative metadata along with the governance processes behind its creation, and by building upon known and open systems agencies, can deliver a stable platform for the sharing of metadata. Along with a providing access to a powerful and standards compliant metadata registry, Aristotle-MDR also features a suite of community supported and enterprise-level extensions to broaden the metadata management capabilities of government, academic and enterprise organisations.
