Modélisation d'événements composites répétitifs, propriétés et relations temporelles

Abstract : Modelling events with their temporal properties concerns many users and scientific communities. We adopted the Object paradigm and designed an operational metamodel which stands as a pivot business independent representation for composite events accompanied with their structural and temporal properties. PTOM metamodel (Periodic Temporal Occurrence Metamodel) accounts for structural constraints upon events and geometric, topologic or relational constraints upon their temporal occurrences. It gives prominence to intensional representations of periodic events occurrences vs extensional ones. PTOM extends ISO 19108 standard and fits EventsML G2 and iCalendar. From a theoretical viewpoint, we extend ALLEN’s and LIGOZAT’s interval algebras and propose a special set of topological relations between non convexintervals (ALLEN*), and study its properties. These results are part of PTOM. The first application of PTOM results in a specification of the Gregorian calendar semantics. Calendar elements are reinserted as periodic events in PTOM thus enhancing its expressiveness. PTOM was also experimented upon a corpus of journalistic (press agencies) events dedicated to leisure and culture at the occasion of an ANR project. Model Driven Engineering was extensively used for PTOM design and use.It allows to manage complexity and to ensure maintainability, consistency and eventually can automatically generate data provider or end user interfaces as well.
