There are several rulesets (RDFS and OWL dialects) that are supported by OWLIM:

More general info about OWL dialects:

RS requirements and notes

  • currently we want to support inverseOf properties
  • a good balanced ruleset is "owl-horst" which supports inverse, transitive, etc. properties
  • a more powerful ruleset is "owl-rl-optimized", in particular it offers property chaining
    • example of property chaining:

Repository creation notes:

  • when a repository is created the ruleset needs to be specified (in Sesame Workbench or programatically)
    • Barry: note that if we use a custom ruleset for, e.g., rso:PS97_from_actor, we will lose the ability to simply specify the ruleset using the available ones in the Workbench
  • however the repository can be exported and reimported with another ruleset
  • there is no practical performance difference between both rulesets for small repositories
