Specifying temporal data models for semistructured data by a constraint-based approach

In the past few years some models for semistructured temporal data, which propose different strategies to deal with temporal dimensions, have been denned. In this paper we analyze these models by applying the recently proposed metamodel GSMM (General Semistructured Meta-Model) for semistructured information. GSMM allows us to represent semistructured temporal data models with a unifying formalism; constraints that are specified in these models are also represented and classified on the basis of their expressiveness.
