README

This is an addon to RDFpro that applies the rules of the Event Situation Ontology (ESO) and creates the resulting Situation(s).

Contents

This repository contains four new processors for RDFpro.

• @esoreasoner [-i] [-b BASE] [-w] FILE... Performs reasoning according to the ESO owl supplied
  • [-i] emits only inferences (default: emit also explicit statements)
  • [-b BASE] use BASE to resolve URIs in the ESO ontology files (default: empty)
  • [-w] rewrites BNodes in the ESO ontology file to avoid clashes
  • FILE... the ESO owl file
• @reformattime Perform filter on time entities, converting single time entities into integer values.
• @filtertype Perform filter on predicates, leaving only one kind of event for each
• @removeobeqsub [-i] Remove triples having the same subject and object
  • [-i] invert the behavior (delete triples with different object/subject)
