The SWRL Temporal Built-In Library is one of the SWRLTabBuiltInLibraries. It defines a set of built-ins that can be used in SWRL rules to perform temporal operations. (92F)
These built-ins are defined in the SWRL Temporal Built-In Library Ontology. It has the default prefix temporal. A copy of this ontology can be found the standard Protege-OWL repositories, and can be imported through the 'Import Ontology' option in the Protege-OWL Metadata tab. (AUG)
The built-ins in this library have two usage modes: (AUH)
- Basic Mode In this mode the built-ins work with temporal information specified by XML Schema date and dateTime types. Details of this mode can be found here. (AUI)
- Advanced Mode In this mode the built-ins work with temporal information described using an interval-based temporal model. This mode is defined by the SWRL Temporal Ontology. Details of this mode can be found here. (AUJ)
