Hi, Paul, thanks for this message, let's see what we can clear up.

First of all, you may find it useful to know that you can omit these
explicit error-checks, at least for one-off command-line programs:
Perl's default behaviour when an object is thrown (i.e. used as the
argument to die()) is just to print it, and the ZOOM::Exception class
renders itself quite nicely.  Of course, you'll still need to catch
exceptions if you want to handle them intelligently, but if all you're
doing it printing them, then there's no need.

Two problems here.  First, _what_ database do you want to drop?  You
need to set its name into the XS package so that the server knows what
you're requesting:
        $Zpackage->option(databaseName => $dbname);

Second, there is a known bug in the database-dropping code that
corrupts the registers:
        http://bugzilla.indexdata.dk/show_bug.cgi?id=447
so please don't do that for now!  (I know it's lame; it'll get fixed.)

>> eval {
>>      my $Zpackage = $Zconn->package();
>>      $Zpackage->option(databaseName => 'Koha');
>>      $Zpackage->send("create");
>> };

That looks fine.

Once more, you win the prize!  (Three in 24 hours.  Good going.)

You're correct, the problem is in the form of the record you're
passing into Zebra.  I am sorry that it's not diagnosed more
explicitly.

Zebra update works with XML, so you'll need to translate the MARC
record into MARCXML and send that.  (Seb, I don't know whether more
configuration is required on the server side to let it understand
what's happening?)

         sucks, but the idea is still good and noble and worth fighting
         for.  And even the current implementation is way better than
         most of the alternatives.
