Furthermore, developers need to edit and compile source code on their local machine. All of these scenarios have in common the need to remotely author and version Web pages, documents, and source code. Together, WebDAV and DeltaV provide an open, standards-based infrastructure that supports these scenarios. Figure 2 - WebDAV Web Site Collaboration. WebDAV provides an exclusive write lock, which guarantees that only the lock owner can overwrite a locked resource, and a shared write lock, which allows a group of collaborators to work together on a resource.
Locks automatically time out, easing administration of a WebDAV server.
Since WebDAV locks exist independent of a TCP connection, it is possible to take out a lock, work disconnected from the network, and then reconnect to submit editing updates. This type of work pattern is very useful for wireless networking, where network connections can frequently get dropped. Also included is the ability to link pages of any media type to related pages. The ability to copy and move Web pages within a server's namespace, and the ability to create and list the contents of collections. The ability to record important states in the evolution of a resource.
