33. © Keith G Jeffery & Anne AssersonCERIF Course: Data Model 1 20021024 33 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

34. © Keith G Jeffery & Anne AssersonCERIF Course: Data Model 1 20021024 34 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

36. © Keith G Jeffery & Anne AssersonCERIF Course: Data Model 1 20021024 36 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
