A "correct" selection of attributes (features) is vital indata mining. As a first step, this paper constructs all possibleattributes of a given relation. The results are basedon the observations that each relation is isomorphic to aunique abstract relation, called canonical model. The completeset of attributes of the canonical model is, then, constructed.Any attribute of a relation can be interpreted (viaisomorphism) from such a complete set.
