I've released XML::Atom, a Perl implementation of all things Atom. The goal for XML::Atom is to provide an implementation of the syndication feed format, the API, and the archiving format planned for Atom. Currently, it provides support for the feed format, and an implementation of a client for the API.
XML::Atom が正式にリリースされたようです。
認証まわりとかが変わったのかな。
要チェキです。
