[2,"smw-datavalue-wikipage-invalid-title","The class “Interval” defined in the OWL-Time ontol-ogy has been extended within this pattern by means of the class “PeriodicInterval”. This concept has been created in order to define periodic intervals. As we have al-ready mentioned, these intervals are defined by four elements, namely, its beginning, its end, the duration of each subinterval and the duration of the period, that is, the gaps between two subintervals. In order to model the beginning and end of the inter-val, we have reused the relationships “hasBeginning” and “hasEnd” already defined in the OWL-Time ontology. By taking advantage of the concepts and relations al-ready defined in the OWL-Time ontology instead of creating new ones we both pro-mote the reuse of existing models and avoid the inclusion of unnecessary complexity within the pattern being developed. The durations of the subintervals and the period between them have been modelled by means of the relationships “hasIntervalDura-tionPerPeriod” and “hasPeriod” respectively. Both relationships are defined between the concepts “PeriodicInterval” and “DurationDescription”."]
