.... beyond the scope of the repository engine, even if that engine supports basic versioning functionality [10] Another example is an object reuse model that covers functions to group objects into catalogs, assign keywords to objects, and connect objects in libraries to the projects that use them [8]. A third example is a workflow model to track the development of an artifact through an engineering process [9] These generic object management functions can be captured in information models that are shared by all tool developers. Within a given area of engineering there are standard types of ....

Software artifacts, organized in Generic Application Frames (GAFs) are stored in the Software Information Base (SIB) [5]. Various approaches exist aimed at providing automatic support for application development; they range from specialized tools for development and for project management, through covering the whole life cycle via a unique support paradigm (e.g. 7] to integrated CASE tools and Software ....

NATURE S SET OF OBJECT SYSTEM MODELS There have been several attempts to produce sets of problem models for reuse during requirements engineering (e.g. Reubenstein Waters 1991, Constantopoulos et al. 1991). However, NATURE represents the first systematic attempt to model the space of requirements engineering problem domains. Its theoretical justification draws on 3 hierarchical models of natural categories (e.g. Rosch 1983) and mental schemata (e.g. Riesbeck Schank 1989) from cognitive ....

Therefore the recording of design rationale (e.g. 84] 89] 53] and the integration of argumentation concepts ....

If the requirements specification of an existing system is not available it can be gained through reverse engineering (e.g. 36] 7] 56] [16]) For both using generic and specific knowledge during the RE process, support for retrieving suitable knowledge must be offered, e.g. using similarity based search approaches (e.g. 39] 16] 92] Third, the current specification of the system can be improved by applying techniques for ....

Such an environment is realized by the ViewPoints approach [Nuseibeh94] Views are distributed over locally managed objects called ViewPoints which act as independent data bases without a central control mechanism. In [Mylopoulos95, Constantopoulos95] an alternative is presented where the views are managed within a central repository but separated by so called contexts.

Adopting this approach, we focus on the problem of defining a quantitative similarity relation between descriptions of software artifacts so as to promote their analogical reuse. The potential of similarity has been pointed out in both the literature relevant to reuse[5,7,8,9] and the literature relevant to analogical reasoning[1,16,30] Also, heuristic realizations of the concept have been exploited in validating and integrating specifications of requirements(e.g viewpoint resolution[22] Similarity has a clear role in analogical reasoning.

TELOS has been chosen because it subsumes the structural constructs of other object oriented data models, and has been acknowledged as language for describing software artifacts[7]. It provides three basic abstractions, namely classification, generalization and attribution. Classification defines an infinite dimension along which objects can be classified into built in disjoint classes that distinguish between the successive levels of classification(i.e Token class, S Class ....
