  text: 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.
    The basic idea is to reuse concepts, which are known within or without the graph
    grammar field, to structure large specifications. These are the concept of distributed
    graph transformation systems, the concept of inheritance of specifications, and
    the import-export-interface concept. 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. This is the basis for an explicit
    integration of these concepts and a corresponding specification language, to be
    discussed in a subsequent paper.

  text: By means of a special sofnvare process model component we have been successful
    in specifring somare process model evolution, This component also handles much
    reuse of software process model fragments. To handle the reuse of the software
    as it is being produced by a software process, another extra component can be
    added to the model for that software process. It is argued why this extra component
    is comparable to the special component for evolution.

  text: This extended abstract describes a mechanism to automatically incorporate
    safety requirements into operational specifications written in Z. 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.

  text: We present the hybrid query language HQL/EER for an Extended Entity-Relationship
    model. As its main characteristic, this language allows a user to usebothgraphical
    and textual elements in the formulation of one and the same query. We demonstrate
    the look-and-feel of this query language by means of examples, and show how syntax
    and semantics of this language are formally defined using programmed graph rewriting
    systems. Although we present the language in the context of the EER model, the
    concept of hybrid languages is applicable in the context of other database models
    as well. We illustrate this claim by discussing a prototype implementation of
    a Hybrid Query Tool based on an object-oriented approach, namely the Object Modeling
    Technique (OMT).

  text: We present a combination of recent extensions to single-pushout graph transformations,
    as there are attribution, application conditions and amalgamated graph transformations
    and add a simple transaction concept on top of this formalism. Thereby, we provide
    the formal basis for several examples, where these concepts are used in combination.

  text: Single pushout graph transformations at injective matches are extended by
    negative application conditions. It is shown, how right-sided application conditions
    can be transformed into equivalent left-sided ones. Based on this result, conditional
    derived rules are introduced and a theorem, similiar to the double pushout embedding
    theorem is shown. Finally, three variants of contextual application conditions
    are discussed with respect to their expressive power and expected results.

  text: Several object-oriented modeling approaches propose to describe the dynamic
    behaviour of objects by state transition diagrams. None of them provides precise
    rules or conditions for the interrelation between the behaviour description of
    classes and those of their subclasses. In this paper, we discuss this interrelation
    in detail. It turns out that one has to distinguish between the observable and
    the invocable behaviour of objects and that different compatibility requirements
    between the diagrams exist depending on the type of behaviour.

  text: Based on a categorical semantics that has been developed for typed graph grammars
    we uses colimits (pushouts) to model composition and (reverse) graph grammar morphisms
    to describe refinements of typed graph grammars. Composition of graph grammars
    w.r.t. common subgrammars is shown to be compatible with the semantics, i.e. the
    semantics of the composed grammar is obtained as the composition of the semantics
    of the component grammars. Moreover, the structure of a composed grammar is preserved
    during a refinement step in the sense that compatible refinements of the components
    induce a refinement of the composition. The concepts and results are illustrated
    by an example.

  text: The overall aim of this paper is a proposal how to bridge the gap between
    formal specification techniques developed in research projects and semi--formal
    or informal specifications used in industrial practice. The main idea to overcome
    these problems is to develop graphical support for formal methods in order to
    increase acceptance by practitioners and to provide means for integration of formal
    and semi--formal methods. More specifically suitable concepts will be developed
    to combine algebraic specifications, Petri Nets, and Graph Grammars with each
    other and with distinguished graphical components to be used by industrial partners.

  text: Currently existing graph grammar-based specification languages have serious
    problems with supporting any kind of “specification-in-the-large” activities.
    More precisely, they have deficiencies with respect to modeling hierarchical data
    structures or specifying meta activities like manipulation of graph schemata.
    Furthermore, already proposed graph grammar module concepts are still too abstract
    to be useful in practice. Our contribution addresses these problems by introducing
    a new hierarchical graph data model with an infinite number of schema, meta-schema,
    etc. layers. It forms the base for a forthcoming concrete modular graph grammar
    specification language where in addition information hiding aspects like explicit
    export and import interfaces are expressible.
