....names of the object in c, iii) every predicate of c is also a predicate of c, and (iv) the reference of every object of c refines the reference of the object in c. Note that the above definition of context refinement is recursive and that every context is a refinement of itself. We show in [39] that refinement is a partial pre ordering, i.e. reflexive and transitive. Moreover, we show that context refinement is a partial ordering up to context equivalence, where context equivalence is defined as follows: two contexts are equivalent if they have (i) the same objects, ii) the same names ....
....of the source reference of the ISA link. In this case, the complete contexts are obtained after the application of reference inheritance on the ISA links. This, however, is an implementation issue that lies beyond the scope of this paper. A mechanism for eliminating duplications is proposed in [39]. Context refinement can be achieved in stages through the repetitive application of the following operations on the contents of a context: i) the addition of a new object (possibly an attribute) ii) the specialization, generalization, or classification of an object (possibly an attribute) ....

....bottom up, or mixed modeling. Moreover, the combination of contextualization with the traditional abstraction mechanisms of classification, generalization and attribution provides further modeling capabilities, which are beyond the scope of this paper. A study of that combination can be found in [30, 27]. 3 Accessing information through paths Accessing information in an information base often involves navigating from one object to another by following links. Navigation is based on the notion of path. We distinguish two kinds of paths: 1. object path, which is a sequence of dot separated ....
