CORES

• Project Update

2
CORES Context

• CORES is an Accompanying Measure under the
  Semantic Web action line (2001-2002)
• It aims to serve the Community of metadata
  implementors, by both
• aiming to enhance interoperability between
  metadata solutions
• providing registration of metadata schemas

3
CORES partners

• PricewaterhouseCoopers, Luxembourg (coordinator)
• Fraunhofer Gesellschaft, Germany
• UKOLN, University of Bath, UK
• MTA SZTAKI, Hungary

4
Activities

• Standards Interoperability Forum
• Perspective standards developers could try to
  define standards and semantics in comparable ways
  so that implementers can understand, interpret
  and apply (combinations of) standards in their
  applications and systems
• CORES Registry
• Building on the work of SCHEMAS, which examined
  how implementers typically mix and match
  multiple standards in their local vocabularies
  and defined a model for declaring such usage in
  Resource Description Framework (RDF) for
  harvesting by registries

5
Goal of Forum

• Bring together key people from metadata standards
  initiatives to discuss issues of cross-standard
  interoperability
• Discuss feasibility of building bridges between
  metadata standards
• Explore potential for building a platform for
  future co-ordination and co-operation
• Feed results into W3C Semantic Web activity and
  other relevant international platforms

Forum participants

• Standards
• CERIF (EuroCRIS)
• Dublin Core (DCMI)
• DOI (IDF)
• IEEE/LOM (IEEE LTSC)
• GILS (USGS)
• ONIX (EDItEUR)
• MPEG (no signature yet)

• Other organizations
• SWAD Europe
• OASIS

Forum meeting took place at CEN premises,
Brussels, 18 November 2002

CORES Resolution

• Whereas
• our metadata standards have elements units of
  meaning comparable and mappable to elements of
  other standards
• We agree
• To assign Uniform Resource Identifiers to our
  elements.
• To articulate and publish specific policies
  regarding the stability, persistence, and
  maintenance of the URIs assigned to the elements.

8
Actions on participants

• Finalise and approve the consensus statement by
  e-mail before end 2002, involving participants
  who could not attend
• Publicise consensus statement to wider audience
  of metadata standards initiatives
• Define and publish URI assignment mechanisms in
  the next half year
• Assign URIs to elements in next half year
• Define and publish URI persistence policies in
  next half year

9
CORES next steps

• Schema Creation and Registration Workshop,
  Budapest, 6/7 March
• Publication of results of CORES project (e.g.
  submitted poster for WWW2003)
• Development of 6th Framework Programme proposal
• Research and coordination issues identified in
  Interoperability Survey and Forum meeting
• Further work in the area of schema registration
  and management
