The central objective of the CORES project is to encourage the sharing of metadata semantics. CORES will address the need to reach consensus on a data model for declaring semantics of metadata terms in a machine-readable way. Consensus on the ground-rules for declaring standard definitions of terms, as well as local usage and adaptations, will enable the diversity of existing standards to “play together” in an integrated, machine-understandable Semantic Web environment.
In order to achieve this level of interoperability, CORES will support applications re-using and adapting terms maintained by key organizations and standardisation initiatives
News from CORES
A paper “Metadata schema registries in the partially Semantic Web : The CORES experience”, by Rachel Heery, Pete Johnston, Csaba Fülöp and Andras Micsik, was given at for DC-2003.
The Final Project Report is available.
An article “Identifying metadata elements with URIs : The CORES Resolution”, by Thomas Baker and Makx Dekkers, was published in the Jul/Aug 2003 issue of DLib.
DOI News reported the International DOI Foundation’s signing of the CORES Resolution.
Standards Interoperability Forum
CORES will bring together key figures from major standardisation activities in a Standards Interoperability Forum to discuss the practicalities of cross-standard interoperability. The goal will be to discuss the feasibility of building semantic bridges between metadata standards within the framework of the Semantic Web
Registry of core vocabularies and profiles
CORES will bring the major standardisation groups together with international initiatives that are exploring the use of metadata schema registries. In order to encourage uptake for methods of declaring “profiles” of application-specific usage, CORES will build on the work of SCHEMAS, which defined a model for declaring such usage in Resource Description Framework (RDF).  CORES will promote use of this model by a critical mass of projects and services by holding a hands-on “profile-writing” workshop with implementers.
