DAML+OIL for Application Developers - slide "Instance Mapping"

different URIs may be used to denote the same instance (individual)
DAML+OIL provides the following properties to map between instances (individuals)
- daml:sameIndividualAs
- daml:differentIndividualFrom

example:


<rdf:Description rdf:about="mailto:hendler@darpa.mil">
  <daml:sameIndividualAs rdf:about="mailto:hendler@cs.umd.edu"/>
</rdf:Description>

just because 2 URIs are different doesn't mean we can assume that they denote different individuals, unless daml:differentIndividualFrom is specified or inferred
