[CWB] CQPweb - managing metadata

[Claudia Borg]

[update]

as a matter of fact, in the running of admin-lib.inc.php around line 380+
there is a piece of code mkdir($datadir, 0775); - this is not working for
me, and infact my /corpora/data/ is empty, when it should have the folder
'examplesimple' in it.

I am running php version 5.3.2-1ubuntu4.2 - I'll try to check why the
directory is not being created...
