We plan the follow major extensions to TCM, to be added in the order mentioned: (1) Addition of hierarchy, so that the enclosure of one node shape by another node shape is relevant information. This allows the representation of hierarchic statecharts, hierarchic DFDs, hierarchic ERDs (with subject areas), packages that enclose other packages or classes, etc. (2) Addition of global constraints for both YSM and the UML, i.e. constraints that involve different diagrams of one coherent model. (3) Addition of executability for both YSM models and UML models. This requires the definition resp. selection of execution semantics for both YSM and UML models.These semantics are sketched in R.J. Wieringa, ``Design Methods for Reactive Systems: Yourdon, Statemate and the UML'', Course Notes, Department of Computer Scienced, University of Twente. To implement this, we will have to make this semantics precise. Interleaved with these major updates, we will continue implementing wishes in the wish list that we deem important. Currently, we are working with roughly one person-equivalent on TCM: Frank Dehne as chief architect, Henk van de Zandschulp as programmer, Roel Wieringa as project leader. Anyone who wants to contribute to the GNU version of TCM made available by the University of Twente, is welcome to do so. The three people just mentioned will take it upon themselves to guarantee consistency and a coherent architecture. Please contact firstname.lastname@example.org if you plan to contribute to TCM. You may want to adhere to a strict separation of specification from implementation in your extensions of TCM. In the directory $TCM_HOME/doc/specs (which is included in the source code distribution) you can find some examples of the way we specify our additions to TCM.
