FEEL: Implement the interval-based algebra functions as defined by J.F. Allen ----------------------------------------------------------------------------- Key: DROOLS-3594 URL: https://issues.jboss.org/browse/DROOLS-3594 Project: Drools Issue Type: Enhancement Components: dmn engine Affects Versions: 7.17.0.Final Reporter: Edson Tirelli Assignee: Edson Tirelli Priority: Major Attachments: ORF2009_Temporal_Reasoning_final.pdf In his paper "An interval-based representation of temporal knowledge", J.F.Allen defines an algebra to resolve interval relationships. This algebra is implemented already in Drools core to deal with events. This ticket is an RFE to implement similar functions in FEEL to support such algebra in DMN. The list of functions is: * before * meets * overlaps * finishes * includes * starts * coincides * after * metBy * overlappedBy * finishedBy * during * finishes Details of the semantics can be found in the attached presentation, slides 24 and 25.
