The
Web Distributed Authoring and Versioning protocol, or
DAV for short. This monster is an extension to the
HTTP protocol that allows web documents to be updated remotely - a sort of
opens source version of
FrontPage Extensions. It will allow people to use their
web server as an advanced
file repository and
concurrent versioning system. It includes
HTTP methods for remotely
locking documents, setting
read/write properties,
namespace management and support for
XML.
The mod_dav module has already been written for apache and there is WebDAV support for IIS (although this is, surprise surprise, non-standard) and other leading web servers. For more information see the RFC2518 or http://www.webdav.org
