Installing GDOME

In future versions of EPrints, XML::LibXML will be the only XML library supported. As this is about as efficient as XML::GDOME but can be more easily installed on various Linux operating systems. Since EPrints 2.2 you may use either XML::DOM or XML::GDOME. XML::GDOME is recommended as it's faster and uses much less RAM, but it does require you to install a whole lot of extra libraries and perl modules. If you are running a pilot or demonstration service then XML::DOM is fine, and you can always switch over later by installing the required tools and setting the GDOME flag in perl_lib/EPrints/SystemSettings.pm
