Objective The objective of practitioner was to develop methods and tools for the pragmatic re-use of software at the design stage. The task was to enable the user to identify, isolate, document, store, retrieve and re-use program concepts (or more generally, software concepts). Techniques from linguistics and from the fields of indexing and information retrieval have been used to analyse existing material. Substantial effort has been spent in carrying out domain analysis work and in developing an appropriate methodology. A number of successive prototype systems have been built, tried out and improved over the duration of the project. PROGRESS AND RESULTS A meta-model for the re-use scenario has been agreed by the partners. In dealing with specific application domains such as process control software for metal working or basic systems software for graphical user interfaces, a questionnaire for the collection and later retrieval of concepts has proved its utility, and the development of tools and methods for the preparation of very specific thesauri for the respective domains has turned out to be very useful. The prototype systems developed for retrieval and re-use (code-named "PRESSTO" and "PRESSTIGE") are based on standard relational database systems and on widespread user interfaces for Unix such as XView and OSF motif. EXPLOITATION PRACTIONER has been combining advanced theoretical research results with pragmatic prototyping and early hands-on experiments, in order to serve its test users at the earliest possible stage. Within the different partners' organisations, exploitation willfollow somewhat different paths. One partner will focus on the utilisation of the domain analysis techniques and on the use of the PRACTITIONER tools within its own organisation: the two other industrial partners will exploit the results within their product developments tasks.
