The CAPE-OPEN Interoperability Workshop is an open session where interested parties may conduct interoperability tests between CAPE-OPEN compliant Process Modelling Environements and CAPE-OPEN compliant Process Modelling Components. The objective is to sort out any interoperability issues that may arise from the various implementations of the CAPE-OPEN interfaces. The CAPE-OPEN Laboratories Network will help achieve this objective by providing a computer where most of the available CAPE-OPEN software are installed. The workshop will be organized so that every organization may have a chance to conduct the tests they need.
