This talk was +prepared by some [[http://labs.rtgi.eu/][$coworkers]] and me. + +We generated two maps (authors and modules) using the CPANTS' data. For +the websites, we crawled a seed generated from the CPAN pages of the +previous authors. + +Each of this graphs are generated using a +[[http://en.wikipedia.org/wiki/Force-based_algorithms][force base +algorithm]], with the help of [[http://gephi.org/][Gephi]]. + +All the map are available in PDF files, in creative common licence.

We selected a +list of modules which are listed as dependancies by at least 10 others +modules, and the modules who used them. This graph is composed of 7193 +nodes (or modules) and 17510 edges. Some clusters are interesting: + +- LWP and URI are really the center of the CPAN +- a lot of web modules (XML::*, TemplateToolkit, HTML::Parser, ...) +- TK is isolated from the CPAN +- Moose, DBIx::Class and Catalyst are forming a group. This data are + from march, we will try to do a newer version of this map this + summer.

Each time an author use a module of another +author, a link is created. + +- Modern Perl, constitued by Moose, Catalyst, DBIx::Class.
