....Egenhofer Herring [17] which is based only on topological properties. Another promising area of research is to consider the expressive power of relational structures more general than BRAs, for example, those, in which the associativity of the composition is relaxed [29] Egenhofer Rodrguez [18] have given a spatial interpretation of such a structure. ....
