First, so-called design views are developed for structuring specifications, that is, a system is modeled according to different views (e.g., representing the needs of different kinds of users) which have to be synchronized afterwards in order to build the whole system. Views can be specified by means of typed graph transformation systems, where the type graph determines the visible types and the productions describe the known operations of that view. The synchronization of views is done by the construction of cooperative parallel composition of graph transformation systems, developed by Leila Ribeiro and presented at the same seminar. If the specification is complete, a view may describe an observation of the system in operation. In this case we speak of a user view. It turns out that the semantics of such a view cannot be described by computations (i.e., graph transformations), but just by observations of computations of the global system. Such observations of computations cannot be represented by graph transformations in the usual sense because a local view may lack operations (productions) of the global system, so that state changes may be observed that do not have a cause in the local view. Therefore, the notion of graph transition is introduced as loose semantics for productions, where the production specifies only a lower bound to the activities that are to happen during application. Contrastingly, in the classical doublepushout approach to graph rewriting, productions are interpreted as complete descriptions of the transformations to be performed. For typed graph transformation systems a transition sequence semantics is developed, comprising all finite and infinite sequences of transitions in a system. Moreover, this semantics is shown to be compositional w.r.t. the synchronization of views.","lang":"eng"}],"publication":"Report on the Dagstuhl-Seminar 9637 on Graph Transformations in Computer Science","type":"conference","title":"Synchronization of Views and Loose Semantics of Typed Graph Productions","date_created":"2019-02-20T14:02:31Z","author":[{"last_name":"Ehrig","full_name":"Ehrig, Hartmut","first_name":"Hartmut"},{"first_name":"Reiko","full_name":"Heckel, Reiko","last_name":"Heckel"},{"full_name":"Padberg, Julia","last_name":"Padberg","first_name":"Julia"},{"full_name":"Taentzer, Gabriele","last_name":"Taentzer","first_name":"Gabriele"},{"last_name":"Wolter","full_name":"Wolter, Uwe","first_name":"Uwe"},{"first_name":"Andrea","full_name":"Corradini, Andrea","last_name":"Corradini"},{"first_name":"Gregor","last_name":"Engels","id":"107","full_name":"Engels, Gregor"}],"date_updated":"2022-01-06T07:03:46Z","publisher":"Technical University of Berlin","page":"11-12","citation":{"ama":"Ehrig H, Heckel R, Padberg J, et al.

Each subspecification describes a certain part of the system. This might be a certain aspect, like the data, dynamic, or functional aspect, as it is known from object-oriented modelling techniques. Or it might be a certain view onto the system, as it is known from database modelling techniques. The talk motivates the usage of views in graph grammarbased specifications. First, the usage of typed graph grammars inherently ensures an integration of the data and the functional aspect within a view. Second, it is explained that it is not appropriate in case of views to have a fixed semantics. The standard fixed semantics, i.e. a graph transformation system, has to be relaxed to a loose semantics, i.e. a graph transition system. This reflects the idea that a view models only a part of the complete system. Other views may overlap a view with respect to data or functionality. A complete system specification is yielded by exploiting the approach of cooperative parallel composition of graph grammars (see talk by Leila Ribeiro).","lang":"eng"}],"author":[{"first_name":"Gregor","id":"107","full_name":"Engels, Gregor","last_name":"Engels"},{"first_name":"Hartmut","full_name":"Ehrig, Hartmut","last_name":"Ehrig"},{"first_name":"Reiko","last_name":"Heckel","full_name":"Heckel, Reiko"},{"first_name":"Gabriele","full_name":"Taentzer, Gabriele","last_name":"Taentzer"},{"first_name":"Andrea","full_name":"Corradini, Andrea","last_name":"Corradini"}],"date_created":"2019-02-20T14:04:54Z","volume":155,"date_updated":"2022-01-06T07:03:46Z","publisher":"Technical University of Berlin","title":"A View-Based Approach to System Modelling","citation":{"ama":"Engels G, Ehrig H, Heckel R, Taentzer G, Corradini A.

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.","lang":"eng"}],"status":"public","type":"report","report_number":"7/96","language":[{"iso":"eng"}],"_id":"8197","department":[{"_id":"66"}],"user_id":"52534","year":"1996","citation":{"short":"M.

For every individual operation the global (i.e. operation independent) safety invariants are transformed into a predicate which is used to extend the original precondiction of the operation. The operation constructed this way shows the same beavior as the original one whenever its post state satisfies the invariant. Otherwise it refuses to do anything. The construction of the precondition can be carried out automatically and a corresponding tool development is in progress.","lang":"eng"}],"type":"conference","publication":"Proceedings of the Workshop on Tools for System Development and Verifcation","main_file_link":[{"url":"http://tfs.cs.tu-berlin.de/"}],"title":"Automatic Integration of Safety Invariants into Z Specifications","date_created":"2019-03-04T12:25:41Z","author":[{"last_name":"Heckel","full_name":"Heckel, Reiko","first_name":"Reiko"},{"full_name":"Conrad, Mirko","last_name":"Conrad","first_name":"Mirko"},{"first_name":"Gottfried","full_name":"Egger, Gottfried","last_name":"Egger"},{"first_name":"Jörg","full_name":"Hiemer, Jörg","last_name":"Hiemer"}],"volume":1,"date_updated":"2022-01-06T07:03:53Z","publisher":"Shaker Verlag","citation":{"apa":"Heckel, R., Conrad, M., Egger, G., &#38; Hiemer, J.
