Additional DAV Projects
DAV is getting deployed widely, both in commercial products from vendors such as Microsoft, Apple, Adobe, and Xerox, and in a variety of open source projects. You can find a comprehensive list at http://www.webdav.org/projects/.
The following sections describe some interesting DAV projects.
In previous sections, it was mentioned how mod_dav allows backend abstraction. The bundled Apache module provides access to the file system, but the Subversion project provides a front end to a source control system. It provides a CVS replacement using DAV as the transport protocol. You can learn more about Subversion at http://subversion.tigris.org.
DAV File Systems
Similar to Microsoft Web folders, Mac OS X provides support for DAV-mounted file systems, as described in http://www.apple.com/creative/webpro/technology/webdav/.
A Linux kernel module enables you to mount a DAV server as a local drive. It can be found at http://dav.sourceforge.net.
Slide is a project from the Apache Software Foundation that provides a Java-based content management framework that uses DAV extensively. You can learn more about Slide at http://jakarta.apache.org/slide/index.html.
Future Enhancements for DAV
Development of the mod_dav Apache module for Apache is currently targeting two areas: support for version control and access control lists.
