Dear all, Is it possible with Koha to store only the book-specific part of an URL in the record for that book ? To explain the queston in more details, suppose all the books are files that can be downloaded from http://someserver.org/download.pl?book=XXXX&format=YYY&volume=ZZZZ Obviously one does not want to repeat the whole URL in all records, since one would have to change all of them, should the server change. A similar question concerns file formats. Indeed, for the computer it may be easier to store in 856$q a MIME media type or even a number referring to an SQL table that describes each format. However one would prefer to display a format descrition. Does koha permit such things ? If it does, how should such functionalities be implemented ? Many thanks in advance for your helo ! Best wishes, Sébastien.
