This RM4TM constrains the definitions of "Topic Maps Applications (TM Applications)", establishing the criteria that such definitions must meet in order to facilitate the achievement of the Subject Location Uniqueness Objective, and to assure that topic maps can be interchanged, understood, and amalgamated predictably, regardless of their governing TM Applications, and regardless of the combinations of TM Applications that may govern the subjects represented by any single topic map graph that may result from amalgamating multiple topic maps.

"Say it once, why say it again." (Talking Heads) Not sure what
criteria there would be in the definition of that can be tested for
presence or absence, other than components.
