Perhaps you want some kind of machinetags implementation? In other words, tag a sample with things like "race:white, gene:XCFR2" and so on. I've not used it, but there is a branch of django-tagging that supports machinetags here: https://code.launchpad.net/~gregor-muellegger/django-tagging/machinetags/ -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.
