Mappingentities
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
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
