TITLE    = Towards a logic-based reconstruction of software configuration
           management
NUMBER   = 92-10
AUTHORS  = Matthias Jarke, Manfred Jeusfeld, Andreas Miethsam, Michael Gocek
PAGES    = 18
ABSTRACT = The efficient configuration and re-configuration of software systems
           has been a major problem in software engineering. A large number of
           solutions has been proposed with different features and
           restrictions. In this paper, configuration management is presented
           from a logic perspective. It is shown that much functionality can
           be generated automatically when configurations are considered
           as views on a deductive database and recent results on deductive
           integrity checking, query optimization, and intensional updates
           are applied

TITLE    = The Three Dimensions of Requirements Engineering
NUMBER   = 92-24
AUTHORS  = Klaus Pohl
PAGES    = 16
ABSTRACT = Requirements engineering (RE) is perceived as an area of growing
           importance. Due to the increasing effort spent for research in this
           area many contributions to solve different problems within RE exist.
           The purpose of this paper is to identify the main goals to be reached
           during the requirements engineering process in order to develop a 
           framework for RE. This framework consists of the three dimensions:
                o  the specification dimension
                o  the representation dimension
                o  the agreement dimension
           Looking at the RE research using this framework, the different 
           approaches can be classified and therefore their interrelationships 
           become much clearer. Additionally the framework offers a first step 
           towards a common understanding of RE. 


TITLE	= Feature-Oriented Classification and Reuse in IPSEN
NUMBER	= 92-35
AUTHORS	= J"urgen B"orstler
PAGES	= 14
ABSTRACT= A successful approach to aid development with reuse is the usage of
          libraries to store software documents. To support the organization
          of such libraries specialized classification schemes evolved. Most
          of the approaches developed so far are not generally applicable for
          two reasons. They are based on more or less static classification
          schemes and/or only consider functional properties of the stored
          documents. To overcome both deficiencies we propose a new approach,
          called feature#oriented classification.
          To use such libraries successfully it is important to be able to
          understand and to adapt the recovered documents. To support
          development for reuse we propose the usage of a sophisticated design
          language to provide developers with a single language in which they
          can adequately document their design decisions.

TITLE    = Theories Underlying Requirements Engineering: An Overview of NATURE
           at Genesis
NUMBER   = 92-36
AUTHORS  = Matthias Jarke, Janis Bubenko, Colette Rolland, Alistair Sutcliffe, 
           Yannis Vassiliou
PAGES    = 16
ABSTRACT = NATURE is a collaborative basic research project on theories 
           underlying requirements engineering funded by the ESPRIT III program 
           of the European Communities. Its goals are to develop
            -a theory of knowledge representation that embraces subject, usage
             and development worlds surrounding the system, including
             'expressive freedoms'
            -a theory of domain engineering that facilitates the identification,
             acquisition and formalisation of domain knowledge as well as
             similarity-based matching and classifying of software engineering
             knowledge
            -a process engineering theory that promotes context and decision-
             based control of the development process.
           These theories are integrated and evaluated in a prototype 
           environment constructed around an extended version of the conceptual
           modeling language Telos.
