The aim of this paper is to report some issues related to problem modeling which arise in the deployment of scheduling components in real world contexts. We pro pose a methodology which enables the end-user to actively participate in the early stages of system development by contributing to the definition of problem instances in terms of domain-specific terminology. The proposed methodol ogy is provided in the form of a scheduling domain def inition language (trivially, called SDDL), which provides a procedural means for building scheduling problems in a "low-level" formalism such as RCPSP/max. We show how the use of SDDL allows to (1) mask the scheduling-related technicalities from the problem designer and (2) provide a means for the fast-prototyping of scheduling applica tions using off-the-shelf general purpose scheduling com ponents.
