Draft standard RFC 2518, "HTTP Extensions for Distributed Authoring", produced by the IETF (Internet Engineering Task Force). WebDAV extends the HTTP (Hypertext Transfer Protocol) Internet protocol in such a way that the content of documents can be accessed directly via the Internet to allow a team to work on the content and structure of a document. For example, the WebDAV technique allows partners in the printing and media industry to access a PDF document simultaneously and apply correction instructions to it.
