  text: The idea of a combined reference model- and view-based specification approach
    has been proposed recently in the software engineering community. In this paper
    we present a specification technique based on graph transformations which supports
    such a development approach. The use of graphs and graph transformations allows
    to satisfy the general requirements of an intuitive understanding and the integration
    of static and dynamic aspects on a well-defined and sound semantical base. On
    this background, formal notions of view and view relation are developed and the
    behaviour of views is described by a loose semantics. View relations are shown
    to preserve the behaviour of views. Moreover, we define a construction for the
    automatic integration of views which assumes that the dependencies between different
    views are described by a reference model. The views and the reference model are
    kept consistent manually, which is the task of a model manager. In case of more
    than two views more general scenarios are developed and discussed. We are able
    to show that the automatic view integration is compatible with the loose semantics,
    i.e., the behaviour of the system model is exactly the integration of the behaviours
    of the views. All concepts and results are illustrated at the well-known example
    of a banking system.

  text: The algebraic approaches to graph transformation are based on the concept
    of gluing of graphs corresponding to pushouts in suitable categories of graphs
    and graph morphisms. This allows one to give not only an explicit algebraic or
    set theoretical description of the constructions but also to use concepts and
    results from category theory in order to build up a rich theory and to give elegant
    proofs even in complex situations. In the previous chapter we have presented an
    overview of the basic notions and problems common to the two algebraic approaches
    the double pushout DPO approach and the single pushout SPO approach and their
    solutions in the DPO approach. In this chapter we introduce the SPO approach to
    graph transformation and some of its main results. We study application conditions
    for graph productions and the transformation of more general structures than graphs
    in the SPO approach where similar generalizations have been or could be studied
    also in the DPO approach. Finally we present a detailed comparison of the DPO
    and the SPO approach especially concerning the solutions to the problems discussed
    for both approaches in the previous chapter.

  text: The algebraic approaches to graph transformation are based on the concept
    of gluing of graphs, modelled by pushouts in suitable categories of graphs and
    graph morphisms. This allows one not only to give an explicit algebraic or set
    theoretical description of the constructions, but also to use concepts and results
    from category theory in order to build up a rich theory and to give elegant proofs
    even in complex situations. In this chapter we start with an overwiev of the basic
    notions common to the two algebraic approaches, the double-pushout (DPO) approach
    and the singlepushout (SPO) approach; next we present the classical theory and
    some recent development of the double-pushout approach. The next chapter is devoted
    instead to the single-pushout approach, and it is closed by a comparison between
    the two approaches.

  text: The concept of views is used on two levels. 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.

  text: A large industrial process, software maintenance, has been modelled by using
    the process modelling language SOCCA. The paper reports about the experiences
    with this trial. In particular, feasibility, expressiveness, quality and the overall
    benefits of a formal SOCCA model are discussed and compared to the formerly existing
    informal process description. In order to illustrate the results, a well chosen
    process model fragment from the larger model is outlined in detail. It addresses
    in particular the human-intensive cooperation within the process and shows the
    seamless combination of technical components and human agent components in the
    SOCCA model. The main conclusions from this trial are that formal SOCCA models
    are suited to model realistic industrial processes and that due to an intrinsic
    modular structure of a SOCCA model, even huge models remain reasonably readable
    and understandable

  text: In order to manage the complexity of large system specifications, they have
    to be decomposed into subspecifications. 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).

  text: Object-oriented specification mechanisms have become famous for modelling
    structure and behaviour together in terms of autonomous objects communicating
    via message passing. However, whereas most object-oriented specification methods
    are strong in modelling the local behaviour of single objects, they fall short
    on modelling the coordinated behaviour and collaboration of several objects together
    The aim of this paper is to contribute to fill this gap. The paper reports on
    concepts, language constructs, and experiences with three collaboration formalisms
    in the area of object-oriented specifications.

  text: The framework of graph transformation combines the potentials and advantages
    of both, graphs and rules, into a single computational paradigm. 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.
