This report describes the Second Process Specification Language (PSL) Roundtable that was held at the University of Maryland, University College on January 13-14, 1999. The Roundtable brought together vendors, endusers, and researchers from different manufacturing-related disciplines to discuss matters of common interest relative to the development of the Process Specification Language. The Roundtable was divided into three topic sessions, focusing on 1) the PSL pilot implementations and future directions for the project, 2) the draft Version 1.0 of the PSL specification, and 3) mapping of the PSL semantic concepts to existing syntactic representations. This paper elaborates onthe results of the discussions in the three topic sessions. The main conclusions of the Roundtable were 1) the overall consensus that the contents of the proposed Version 1.0 specification (with a few minor additions) provided a good foundation for future work and 2) an identified set of application areas and directions should be pursued.
