The Methods & Tools Special Interest Group is developing the specification for the installers of COBIA middleware and COBIA Software Development Kit (SDK). This textual specification has been provided to the Interoperability Special Interest Group to evaluate its completeness and the ability for a 3rd party to implement based on documentation. Comments made by Michael HALLORAN have been passed to the Methods & Tools Special Interest Group and taken into account:: findings on context have been incorporated into document, Methods & Tools Special Interest Group still needs to do more work since current content may not sufficient for developer of installer. The document will have to be reviewed again by Michael HALLORAN.

Information was shared on 3rd parties capable to develop the COBIA installers, after various contacts with these parties.

The COBIA installer specification document does not evaluate the amount of work necessary to implement the specification. Michael HLAVINKA and Jasper van BATEN however evaluated the work to be a matter of days not weeks. Malcolm WOODMAN will ask Michael HALLORAN for his experience with COLTT and CAPE-OPEN Type library/Primary Interop Assembly installers.

It was discussed if a Symbol Server is required along with COBIA distributed DLLs. It could be a separate repository project and would not be included in any installation package. It was also made clear that no COBIA Primary Interop Assembly will be required until COBIA Phase 3 where marshalling with .NET is considered.

Michel PONS reported on the issue of which license model will be applied to COBIA: CO-LaN Management Board has approved a budget for seeking legal advice on the matter. The contract with a professional legal team is under review and should be signed by CO-LaN in the next few days.

Malcolm WOODMAN reported on the on-going renewal of the code-signing certificate that CO-LaN holds with DigiCert. It was confirmed that installers are timestamped as well as the files (DLL/EXE) they are deploying, so installers do not need to be recompiled once the certificate has reached its term: the certification will appear as valid even after the current certificate has expired.

Further investigation by Michael HALLORAN has not progressed on issues encountered while trying to apply versioning on installers. Michael HLAVINKA will contact Michael HALLORAN to offer assistance in the matter.

The next joint meeting of the Methods & Tools Special Interest Group and of the Interoperability Special Interest Group is scheduled for May 1st, 2019.
