Mappingentities

Page 8: RDA: thinking globally, acting globally Gordon Dunsire Presented at International Developments in Library Linked Data: Think Globally, Act Globally – Part.

Top-downExamine local schema Identify the common elementsCreate a common/global element set (RDF)Refine the global element set to connect down (map) to

specific local elements Issues

Common elements may not cover the same space as local elementsRefinement not possibleCommon elements have to be augmented

Favours the global over the localEncourages a good-enough approach

Page 9: RDA: thinking globally, acting globally Gordon Dunsire Presented at International Developments in Library Linked Data: Think Globally, Act Globally – Part.

Bottom-up

Publish the local schema(s) in RDFMap local elements from different schema to

lowest common (dumber) elements – add new elements if necessary

Continue until all local schema have been mappedIssues

Multiplicity of RDF element setsFrequent overlap and redundancy

Local management resources
