The document discusses the Atom Publishing Protocol (AtomPub or APP), which is a standardized protocol for publishing and transferring content to and from websites. It specifies Atom as a format for organizing content into feeds and entries that can be edited using RESTful verbs. AtomPub allows publishing content to collections on a website using the Atom format and supports features like categories, editing entries, and accepting content. It has been adopted by companies like Google and is seen as an open standard.
