# 1. project A 2.0 is analyzed -> new snapshot A with qualifier TRK
# 2. project B, which depends on A 1.0, is analyzed -> new snapshot A 1.0 with qualifier LIB.
# 3. project A has 2 snapshots : the first one with qualifier=TRK has measures, the second one with qualifier LIB has no measures. Its version must not be used in time machine
# That's why the 2 following SQL requests check the qualifiers (and optionally scopes, just to be sure)
