This document describes Plagger, a pluggable RSS/Atom aggregation and remixing platform. Plagger allows users to create custom applications by combining subscription, filtering, and publishing plugins in different configurations. Examples provided include aggregating Bloglines feeds to Gmail, an IRC bot that notifies about new RSS items, creating a planet site by merging many feeds, and downloading videos from YouTube feeds. The core features of Plagger include automatic RSS/Atom feed discovery and support for various feed formats. Plugins can be combined like Lego blocks to build many different types of applications.
