In this paper we survey recent developments in applying graph transformation as a rule-based framework for the specification and development of systems, languages, and tools. After presenting the basic features of graph transformation, we discuss a spectrum of applications including the evaluation of functional expressions, the specification of an interactive graphical tool, an example specification for abstract data types, and the definition of a visual database query language. The case studies indicate the need for a graph transformation language that provides suitable structuring principles and is independent of a particular graph transformation approach. To this end, we sketch the basic features of the new graph- and rule-centered language Grace, currently under development, that permits systematic and structured specification and programming based on graph transformation.}}, author = {{Andries, Marc and Engels, Gregor and Habel, Annegret and Hoffmann, Berthold and Kreowski, Hans-Jörg and Kuske, Sabine and Plump, Detlef and Schürr, Andy and Taentzer, Gabriele}}, publisher = {{University of Bremen, Department of Mathematics and Computer Science}}, title = {{{Graph Transformation for Specification and Programming}}}, year = {{1996}}, } @techreport{8198, author = {{Busatto, Giorgio and Engels, Gregor}}, publisher = {{Vakgroep Informatica, Rijksuniversiteit Leiden}}, title = {{{Definition of an Encapsulated Hierarchical Graph Data Model: Static Aspects, Part 1.}}}, year = {{1996}}, } @techreport{8199, author = {{Engels, Gregor and Groenewegen, Luuk and Kappel, Gerti}}, publisher = {{Vakgroep Informatica, Rijksuniversiteit Leiden}}, title = {{{Object-oriented Specification of Coordinated Collaboration}}}, year = {{1996}}, } @techreport{8200, author = {{Heckel, Reiko and Corradini, Andrea and Ehrig, Hartmut and Löwe, Michael}}, title = {{{Horizontal and Vertical Structuring of Typed Graph Transformation Systems}}}, year = {{1996}}, } @inproceedings{8271, author = {{de Bunje, Tineke and Engels, Gregor and Groenewegen, Luuk and Heus, Michael and Matsinger, Aart}}, booktitle = {{Proceedings of the Workshop on Software Process Technology (EWSPT 1996), Nancy (France)}}, pages = {{183--187}}, publisher = {{Springer}}, title = {{{Towards Measurable Process Models}}}, doi = {{http://dx.doi.org/10.1007/BFb0017743}}, volume = {{1149}}, year = {{1996}}, } @inproceedings{8272, abstract = {{The paper presents a conceptual framework for a module concept for graph transformation systems from a software engineering as well as from a theoretical point of view.

All these concepts are presented in a uniform framework based on the syntactical notion of a graph class specification and its semantics given by a graph transformation system.
