The original database author clarified that org1 (org:organization) and
org2 (tm:secondaryOrganisation) have different semantics: org2 represents a
group/organisation within which someone did work at org1. Removing and
promoting secondary organisations was losing this information.
Remove the two queries (001-remove-duplicate, 002-promote-secondary) and
regenerate graph-07.ttl and graph-08.ttl.
- Remove redundant tm:secondaryOrganisation when it equals org:organization (230)
- Promote tm:secondaryOrganisation to org:organization when no primary exists (256)
- Replace tm:PersonProfession intermediate class with direct schema:hasOccupation
links from persons to schema:Occupation instances (742 instances removed)
- Remove tm:PersonProfession class and its properties from the ontology
- Add step-07 binary, Rakefile task, figures, and documentation
