The Interoperability SIG met from 9 am till 10 am European Central Time.


Maintenance and development of CO-LaN software tools


Malcolm WOODMAN, Michael HALLORAN (Contractor to CO-LaN), Michel PONS (Contractor to CO-LaN as Chief Technology Officer)



Michel PONS reports on current status of COBIA, and especially on current outstanding issues, i.e. threading model and persistence. A joint meeting between the Interoperability SIG and the Methods & Tools SIG is tentatively proposed on February 7 with topics such as:

  • Develop full test plan (acceptance tests & release tests, plus sufficient testing to authorise Phase 3
  • Identify areas where Michael’s expertise is required to complete steps in the test plan

CAPE-OPEN Type Libraries and Primary Interop Assemblies installers

At the CAPE-OPEN 2017 Annual Meeting, feedback was provided on using these tools. Based on this, Michael HALLORAN has indentified that a “per user” install does not update the GAC. They could be installed in any random directory. Solution to be investigated.

As a test of how to deal with versioning of the CAPE-OPEN IDL, Michael HALLORAN has developed a v1.2 Type Library Installer, including the Flowsheet Monitoring IDL This v1.2 Type Library Installer demonstrates that CO-LaN can manage “additive changes” in a forward compatible way. Further developments awaits outcome of versioning discussions – joint meeting with Methods & Tools SIG.

Tester Suite

Michel PONS has provided Linde with samples of specification documents for elements of the current Tester Suite. This is to progress the decision progress of establishing a Certification SIG. Various considerations are made by the Interoperability SIG, listing  a number of points to be covered in the definition of the Certification Suite software meant to replace the current and old Tester Suite.

CAPE-OPEN Logging and Testing Tool (COLTT)

Michael HALLORAN will test installation of 64-bit version, to investigate missing system file (track issue #209). The Roadmap document for COLTT needs to be merge with COLTT specification document since the two documents have a large overlay.

Next meeting is scheduled on January 29, 2018.



Any CO-LaN member with interest in the development of the set of software tools offered by CO-LaN is welcome to join. Please contact Malcolm WOODMAN, leader of the Interoperability SIG for further information.
