In this paper we define ST2 ODMGe, a multigranular spatio-temporal model supporting evolutions, which encompass the dynamic adaptation of attribute granularities, and the deletion of attribute values. Evolutions are specified as Event - Condition - Action rules and are executed at run-time. The event, the condition, and the action may refer to a period of time and a geographical area. The evolution may also be constrained by the attribute values. The ability of dynamically evolving the object attributes results in a more flexible management of multigranular spatio-temporal data but it requires revisiting the notion of object consistency with respect to class definitions and access to multigranular object values. Both issues are formally investigated in the paper.||Funding Details:||Science Foundation Ireland ; Irish Research Council for Science, Engineering & Technology||Type of material:||Conference Publication||Publisher:||Springer-Verlag||Copyright (published version):||Springer-Verlag Berlin Heidelberg 2009||Keywords:||Spatio-temporal multi-granularity; Evolution of spatio-temporal objects||Subject LCSH:||Object-oriented methods (Computer science)
