Jasper van BATEN informed Methods & Tools Special Interest Group of the issues encountered with fixing ticket 133. Hopefully the issue will be better understood in the next few days and fixed. Otherwise it could impact the approach taken with synchronizing access to COBIA objects from COM. Michel PONS reported also that the development of distribution packages has been successfully checked till commit 303 included, in order to be ready for distribution as soon as a fix to ticket 133 is committed.


Modifications were brought to the Versioning protocol document on two main aspects: license files have been listed as CAPE-OPEN artefacts to which a versioning scheme applies, and many technical details have been added around the registration of CAPE-OPEN applications both in COM and COBIA: a change in the way the CAPE-OPEN version supported by an application is recorded will appear in CAPE-OPEN versions above 1.2. This is explained now as well. These additions do not change the versioning protocol. They rather explain how notification of version supported takes place.

Its charter is: “Improve integration, and expand utilization of Computer-Aided Process Engineering (CAPE) applications within the enterprise through identification and resolution of existing cross-cutting issues with the CAPE-OPEN platform, develop mechanisms for use of CAPE within other application domains, and incorporate advances in information technology into the CAPE-OPEN platform.”
