C. Combi, B. Oliboni, E. Quintarelli "A Unified Model for Semistructured Temporal Data (Extended Abstract)"

Keywords: semistructured data, temporal model, constraints

We propose the unified semistructured temporal data model GEM (Graphical sEmistructured teMporal): it is a graph-based data model and allows one to uniformly capture different temporal aspects of semistructured data. Temporal dimensions, such as valid time, can be suitably modeled by defining temporal constraints among labels of nodes and arcs of the graph representing data. We also propose and discuss operations for manipulating GEM temporal graphs.
