In this article we have presented a new scheme for reasoning with points in 2D-space, called Star-ontology(6), and presented the current results of our study on complexity of reasoning with incomplete/disjunctive information using this new ontology. In this paper we have also proposed a generalized framework Star-ontology(a) for an integer a, that could be specialized to many ontologies including some of the known ones like the 2D Cardinal-directions ontology. This generalization also points to an interesting direction for investigation in the field of spatio-temporal reasoning.
