    88The user is presented a GUI where he can compile an adequate metadata schema for a metadata description by selecting metadata components from a so called "metadata  component registry". These components all are supposed to describe a particular aspect of a resource. For instance an "ActorLanguage" component will describe all relevant aspects of a language available to an actor. Another component "Location" may describe relevant aspects of a region or town that a researcher finds useful to describe, as where e.g. a recording took place. Such components can be aggregated into a single metadata description. To overcome problems with semantic interoperability every metadata element in a component has to have a reference to a concept registry as do the components as a whole.

    1212Users must also be able to create their own components either on the basis of aggregating existing components into new ones, or by defining completely new ones as long as the elements have references to an accepted concept registry. It has always been clear that we need to seed the initial component registry with components taken from the existing metadata sets so that we can achieve interoperability with the huge existing installed base of metadata descriptions such as those of IMDI, OLAC, TEI, etc. Determining the set of CLARIN interoperable metadata sets is political sensitive; every such set will require resources.

    1818The second major function of the CMDI is to harvest available metadata descriptions and store them into central metadata element repositories. In CLARIN only suitable offerings of metadata are accepted, those that use metadata components whereof all elements have references to accepted concept registries. Such metadata element repositories should offer a metadata search & browsing service to the user community.
