© Keith G Jeffery & Anne AssersonCERIF Course: Data Model Exchange Model and Metadata Model Exchange Model Project and Contact Entities always present Can specialise thereafter as –Expertise –Results –Funding –Services and Equipment Depending on kind of CRIS and need for exchange

© Keith G Jeffery & Anne AssersonCERIF Course: Data Model

© Keith G Jeffery & Anne AssersonCERIF Course: Data Model Exchange Model and Metadata Model Metadata Model A model which should be a subset of any CRIS Used to provide an entry representing an instance within the CRIS to a catalog system Used to provide to harvesting engines (WWW) a description of an instance within the CRIS

© Keith G Jeffery & Anne AssersonCERIF Course: Data Model Exchange Model and Metadata Model Metadata Model A trade-off between Enough information for the purposes –Data exchange –Catalog providing homogeneous access over heterogeneous information Minimal information –Commercial exploitation of the full CRIS represented by the metadata –Data storage and communications costs

© Keith G Jeffery & Anne AssersonCERIF Course: Data Model

© Keith G Jeffery & Anne AssersonCERIF Course: Data Model Exchange Model and Metadata Model Metadata Model Fewer attributes in base entities –Person, Project, OrgUnit Full attribute set in Contact Minimum use of language base tables Minimum use of lookup tables Use of ‘X’Additional (where ‘X’ is base table) to indicate which entities are present in full CRIS
