Today, the World Wide Web Consortium has made available the namespace document for the RADion specification at the following URL http://www.w3.org/ns/radion . The publication of this namespace document is important, as it defines elements that are common among the ADMS, DCAT and ADMS.SW vocabularies. .

RADion is an abstract layer that ensures interoperability between metadata vocabularies.It is not the primary intention that repository owners redesign or convert their current systems and data to conform to RADion. It can be a foundation to develop domain-specific metadata vocabularies.
