The reference-implementation.zip contains following archives:
rhdm-7.5-employee-rostering.zip
rhdm-7.5.0.redhat-00002-optaweb-vehicle-routing.zip
rhdm-7.5.0.redhat-00002-openshift-drools-hacep-distribution.zip

Opposed to the first one - employee-rostering - the other files contain exact build version in their names. Not only is this naming inconsistent across other deliverables (see e.g. add-ons.zip), but it also makes automated checking of these deliverables much more difficult.

Could you please change the assembly so that all the archives inside reference-implementation.zip follow the pattern ${product}${majorVersion}.${minorVersion}${name}.zip ?
