Hi Hector, Ahh, I did see something about that. Well, after looking through the source code, it looks like Moose and MooseX::ArrayRef are only used in RDF/Trine/Parser/Turtle/Token.pm and RDF/Trine/Parser/Turtle/Lexer.pm, so if we don’t load those modules, then we won’t need to actually ‘use’ Moose. In the past, I think the fear has been that using Moose with CGI would slow down Koha too much, but Plack would solve that since it would load it at startup and keep it in memory for all the requests without having to reload for each page request. My work with RDF::Trine is in a daemon which doesn’t interact directly with end users, and the performance seems fine to me, although I’m using RDF/Trine/Parser/RDFXML.pm which doesn’t use Moose it seems.

The policy was not to use Moose about some problems with Koha. I don't know if this policy has been change since the introduction of Plack. Regards.

It works great overall, although I found a bug with RDF::Trine::Store::SPARQL version 1.016 (most current version on CPAN*). I sent in a pull request yesterday (https://github.com/kasei/perlrdf/pull/147) and the author of the module said that he's hoping to review it and merge it into master in the next few days. But what this means is that we'll be wanting to use the latest version of RDF::Trine, and that's going to be much newer than what is in the Debian repositories for Jessie and Wheezy. I've taken a peek at the code in those repos, and it's buggy too. I seem to recall on https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=13642 that there were some issues packaging RDF libraries, but I think it may have mostly related to RDF::Helper, of which we have no need. But Mirko if I could get your input, that would be great. *Actually it seems the latest version in CPAN is newer than master in Github. I'll have to talk to the maintainer about that too.
