The OPUS pipeline which employs a blackboard architecture has been processing data at the Hubble Telescope for nearly a year. OPUS was designed both for reusablility and extensibility at the Institute, as well as portability to different platforms and projects. OPUS contains a toolkit of resource files and programs which provide the user with the ability to customize their own pipeline. The ASCII resource files can be used to define the configuration of the system, and to add processes to the pipeline dynamically. The OPUS callable routines provide applications with even more flexible methods of interfacing with the OPUS blackboard. This paper will discuss how the OPUS toolkit, both the resource files and the software libraries, is used to configure an OPUS data processing pipeline.
