Increasing CMDI's Semantic Interoperability with schema.org.

The CLARIN Concept Registry (CCR) is the common semantic ground for most CMDI-based profiles to describe languagerelated resources in the CLARIN universe. While the CCR supports semantic interoperability within this universe, it does not extend beyond it. The flexibility of CMDI, however, allows users to use other term or concept registries when defining their metadata components. In this paper, we describe our use of schema.org, a light ontology used by many parties across disciplines.
