PCTE (A Basis for a Portable Common Tool Environment) is a Public Tool Interface (PTI) intended to provide a basis on which to construct an Integrated Project Support Environment (IPSE). Thus, PTIs are primarily concerned with IPSE needs. This paper shows that applications other than IPSEs also benefit from PTIs, by examining the design, on PCTE, of a management subsystem for structured documents It goes on to describe a prototype of such a subsystem, a hypermedia kernel named Hyperbook. Finally. in the light of this case study, we discuss the feasibility and adequacy of using PCTE for such non-IPSE applications.
