Yes and no. Yes, it will be in v12, but no, not only that will be.

Yes, I need to bootstrap the v12 public database on that server
and make sure the cron script has access ;-)

are the relevant Python source files. Note that for more than absolute
basic meaningful testing one needs to have the German drug database
MMI/Gelbe Liste installed either in Wine or in native Windows. The
GNUmed project cannot and will not distribute that to users.

I guess so. Will keep the list posted about my progress.

For reference: the German MMI/Gelbe Liste also supports interaction
checks. It even supports an interface to that so GNUmed can say:

  "look for interactions between the following drugs and display them"

(this is already implemented ;-)

It got a drawback, though, in that it needs enumerating drugs by
their PZN (Pharma Zentral Nummer - the German central drug number,
handed out by the German FDA). I plan on gently prodding them to
consider doing this via ATC but medically even the highest degree of
granularity isn't sufficient for entirely safe interaction checking
(because there's interactions between non-ATC components of drugs).

However, the GNUmed schema allows to store one generic external
opaque code per drug brand which I plan on using for storing PZNs
and equivalents. Data in that field will be expected to follow a
micro-format such as "<issuer>::<value>" such that meaningful
processing can take place on that.
