Experiences with a faceted classification scheme in a large reusable software library (RSL)

This paper presents experiences with software classification in a large corporate reuse software library (RSL) at IBM. We use facets extensively as one method of component classification in the IBM RSL. However, facets alone cannot adequately provide all the information needed to fully classify and understand a reusable component. Experience with an operational RSL reveals that we require a combination of classification techniques to meet the needs of software developers. Following an overview of the IBM classification method, we discuss the issues surrounding the use of facets and software classification in a large reuse system and give techniques used at IBM to address those issues
