Comments on ontologies
Un article de Caverne des 1001 nuits.
Some comments can be made about ontologies.
Comment 1: They are a data centric approach. Data is not absolute in itself and is a consequence of the point of view of the viewer.
Comment 2: Problem in design between concept and attribute. Attribute can be a concept also. We are coming back to OO class diagram design issues.
Comment 3: Ontologies are too generic as a tool. There can be intermediate level of abstractions.
Comment 4: This is a big one. Ontologies should be able to represent much more than classic OO concepts. It could be possible to generalize the "instance of" concept. A is an instance B that is an instance of C. Generally, in language complexity, we can see this kind of multiple levels of instantiations.
