CORES - A Forum on shared metadata vocabularies

CORES logo



This page describes some of the activities that were undertaken between 2002 and 2003 by staff at UKOLN as part of the CORES project


The CORES project was funded as part of the Information Societies Technology (IST) Programme, under Key Action 3 managed by the Information Society Directorate-General of the European Commission. CORES was a 15 month project which ran from April 2002 to June 2003.

The central objective of the CORES project was to encourage the sharing of metadata semantics. It was intended that CORES would address the need to reach consensus on a data model for declaring semantics of metadata terms in a machine-readable way. The premise was that consensus on the ground-rules for declaring standard definitions of terms, as well as on local usage and adaptations, would enable a diversity of standards to "play together" in an integrated, machine-understandable Semantic Web environment.

In order to achieve this level of interoperability, CORES intended to support applications re-using and adapting terms maintained by key organizations and standardisation initiatives

WP2: Declaring core vocabularies and profiles

WP Leader: UKOLN.

CORES intended to bring major standardisation groups together with international initiatives that were exploring the use of metadata schema registries. In order to encourage uptake for methods of declaring "profiles" of application-specific usage, CORES built on the work of SCHEMAS, which had defined a model for declaring such usage in Resource Description Framework (RDF) [1]. CORES promoted use of this model by a critical mass of projects and services by holding a hands-on "profile-writing" workshop with implementers.
