Warning This page is under development as part of the EPrints 3.0 manual. It may still contain content specific to earlier versions. Manuals for previous versions of EPrints are also available.

You've just installed EPrints 3 and created a repository, and now you're keen to get started on customising it. Before diving into the how-tos, take some time to read through this brief orientation guide and familiarise yourself with the EPrints configuration landscape.

Where are the configuration files?

The default installation directory for EPrints is:

/opt/eprints3/

(you may have chosen a different installation directory when you installed EPrints).

There are several sub-directories at this level, but from a configuration perspective we are interested only in the lib directory and the archives directories. Before looking at the contents of these directories, we need to understand the concepts of global and repository-specific (or sometimes local)

configuration.

Global vs Local configuration

A single installation of EPrints on a server can run multiple repositories, which may each be very different in style and functionality. Therefore, EPrints divides its many configuration files into two default sets: global configuration files and repository-specific configuration files. Multiple repositories under the same installation of EPrints share the global configuration files, but each repository has its own set of repository-specific configuration files.

EPrints strikes a sensible balance between the two. The default global set contains the configuration options that you are probably least likely to need to change (although this is by no means set in stone - you can override a global configuration setting for a specific repository if you need to), whereas the repository-specific sets, on the other hand, contain the most often tweaked configuration settings.

What about everything else? The EPrints installation directory contains several other files and directories, which are described in the EPrints Directory Structure section of the Technical Reference.

The lib directory

The lib directory is where the global configuration files are kept.

The archives directory

Each repository under the same installation of EPrints has its own subdirectory (named after the repository ID specified when creating the repository) under the archives directory. Each of these subdirectories contain the repository-specific configuration files (amongst other files) for that particular repository.
