Applying Hypertext Structures to Software Documentation

Software documentation represents a critical resource to the successful functioning of many enterprises. However, because it is static, documentation often fails to meet the needs of the many diverse users who are required to consult it on a re gular basis in the course of their daily work. Software documentation is a rich resource that has not been fully exploited. Treatment of software documentation presents a number of interesting problems that require a blend of information retrieval and hypertext techniques for their successful solution. The evolving nature of a softw are project and the di verse demands on its documentation present an especially challenging environment. This is made even more challenging by the variety of information resources, ranging from formal specification languages to source code, that must be inte grated into a coherent whole for the purpose of querying. In this paper we discuss work in progress at the University of Virginia. We discuss the issues involved with automating the management of software documentation to better increase its utility. We describe a prototype system, SLEUTH, currently under investigation as a vehicle for software documentation management. The prototype maintains software documentation as a h ypertext with typed links for the purpose of browsing by users with varying needs. These links are generated mechanically by the system and kept accurate under update. Appropriate authoring tools provide the system with the information it needs for this maintenance function. Ad hoc querying is provided over the documentation and h ypertext documents are synthesized in response to these queries.
