After the fix recommended by @matentzn a new release has been run but AISM terms are still missing.
Missing properties were added to the properties to keep file. All changes are now committed to the main repository.
One of such terms: AISM_0000407 is currently present in colao/src/ontology/imports/aism_import.owl but not in colao/imports/aism_import.owl
It looks like something is not right somewhere in the release process, even though the release was successfully run in the computer?
