> 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.
