ISSN Datatype
-------------
0. Intro
--------
The ISSN (International Standard Serial Number) is an eight-digit number
which identifies periodical publications as such, including
electronic serials. See for more information
The structure of an ISSN is similar to an ISBN, but the ISBN datatype
can't be used for an ISSN. That's why we developed the ISSN datatype.
The ISSN datatype is based on the standard ezp 3.x ISBN datatype, and
is made as an extension so it shouldn't cause any problems for future
upgrades.
1. Installation
---------------
Follow these steps to add the ISSN datatype to your ezp installation:
1) Extract the archive into the /extension directory
2) Edit site.ini.append in /settings/override. Add the following to the
file:
[ExtensionSettings]
ActiveExtensions[]=issn
If you already have the [ExtensionSettings] block, just add the second
line.
That's it! :)
NOTE: If you renamed the "issn" folder after extracting the archive, don't
forget to check the "settings" folder of the extension or it won't
work.
