The Unified Modeling Language (UML) is the de facto industrial standard of an object-oriented modeling language. It consists of several sublanguages which are suited to model structural and behavioral aspects of a software system. The UML was developed as a general-purpose language together with intrinsic features to extend the UML towards problem domain-specific profiles. The paper illustrates the language features of the UML and its adaptation mechanisms. As a conclusion, we show that the UML or an appropriate, to be defined core UML, respectively, may serve as a universal base of an object-oriented modeling language. But this core has to be adapted according to problem domain-specific requirements to yield an expressive and intuitive modeling language for a certain problem domain.}}, author = {{Engels, Gregor and Heckel, Reiko and Sauer, Stefan}}, booktitle = {{Proceedings of the 21st International Conference on Application and Theory of Petri Nets (ICATPN 2000), Aarhus (Denmark)}}, pages = {{24--38}}, publisher = {{Springer}}, title = {{{UML - A Universal Modeling Language?}}}, volume = {{1825}}, year = {{2000}}, } @inproceedings{7874, author = {{Engels, Gregor and Groenewegen, Luuk}}, booktitle = {{Proceedings of the Conference on The Future of Software Engineering - Special Track at 22nd International Conference on Software Engineering (ICSE 2000), Limerick (Ireland)}}, pages = {{103--116}}, publisher = {{ACM Press}}, title = {{{Object-Oriented Modeling - A Roadmap}}}, year = {{2000}}, } @inproceedings{7875, abstract = {{In this paper, dynamic meta modeling is proposed as a new approach to the operational semantics of behavioral UML diagrams. The dynamic meta model extends the well-known static meta model by a speci.cation of the system’s dynamics by means of collaboration diagrams. In this way, it is possible to de.ne the behavior of UML diagrams within UML. The conceptual idea is inherited from Plotkin’s structured operational semantics (SOS) paradigm, a style of semantics speci.cation for concurrent programming languages and process calculi: Collaboration diagrams are used as deduction rules to specify a goal-oriented interpreter for the language. The approach is exemplified using a fragment of UML statechart and object diagrams. Formally, collaboration diagrams are interpreted as graph transformation rules. In this way, dynamic UML semantics can be both mathematically rigorous so as to enable formal specifications and proofs and, due to the use of UML notation, understandable without prior knowledge of heavy mathematic machinery. Thus, it can be used as a reference by tool developers, teachers, and advanced users.}}, author = {{Engels, Gregor and Hendrik Hausmann, Jan and Heckel, Reiko and Sauer, Stefan}}, booktitle = {{Proceedings of the 3rd international conference on the Unified Modeling Language (UML 2000), York (UK)}}, pages = {{323--337}}, publisher = {{Springer}}, title = {{{Dynamic Meta-Modeling: A Graphical Approach to the Operational Semantics of Behavioral Diagrams in UML}}}, doi = {{http://dx.doi.org/10.1007/3-540-40011-7_23}}, volume = {{1939}}, year = {{2000}}, } @inproceedings{7876, author = {{Hendrik Hausmann, Jan}}, booktitle = {{Proceedings of the Informatiktage 2000, Bad Schussenried (Germany)}}, pages = {{103--107}}, publisher = {{Konradin Verlag}}, title = {{{Graphtransitionsregeln zur Beschreibung der Semantik von UML}}}, year = {{2000}}, } @inproceedings{7877, author = {{Mehner, Katharina and Wagner, Annika}}, booktitle = {{Proceedings of the IEEE International Symposium on Visual Languages (VL 2000), Seattle (Washington)}}, pages = {{199--206}}, publisher = {{IEEE Computer Society}}, title = {{{Visualizing the Synchronization of Java-Threads with UML}}}, year = {{2000}}, } @inproceedings{7878, author = {{Depke, Ralph and Heckel, Reiko and Küster, Jochen}}, booktitle = {{Proceedings of the conference on Autonomous agents (AGENTS 2000), Barcelona (Spain)}}, pages = {{82--83}}, publisher = {{ACM Press}}, title = {{{Integrating visual modeling of agent-based and object-oriented systems}}}, doi = {{http://dx.doi.org/10.1145/336595.337052}}, year = {{2000}}, } @inproceedings{8124, author = {{Krauter, Stefan and Araujo, R.
