Realising a Federation of Repositories of Reusable Metadata.

Semantic assets and the agreements associated with them are essential elements for organisations to understand the meaning of the information they exchange - without them this information would be of little use. In order to facilitate the access of public administrations in Europe to reusable semantic assets, the Interoperability Solutions for European Public Administrations Programme of the European Commission (ISA Programme) has been running for the last 3 years an action on syndicating content from different semantic asset repositories and making it available through a single point of access. In this paper we present the current state of the federation of semantic asset repositories on Joinup, namely a set of online collections of semantic assets maintained by public administrations, standardisation organisations and businesses, which currently counts more than 1500 semantic assets from 21 partner organisations, described using the Asset Description Metadata Schema (ADMS).
