CMDI (Component Metadata Infrastructure)

The Component Metadata Infrastructure provides a framework to create and use self-defined metadata formats. It relies on a modular model of so-called metadata components, which can be assembled together, to improve reuse, interoperability and cooperation among metadata modelers. The model is standardised in ISO 24622-1 and ISO 24622-2. The serialization is typically in XML. Metadata in this format are often distributed via OAI-PMH. The definition of data categories is provided externally, for example by linking to schema.org or the Clarin Concept Registry.
