Apple's MAC OS X server now includes a CalDAV server. CalDAV supporting clients, like Apple's iCal can now remotely schedule meetings using the open, interoperable CalDAV protocol. This is an important step towards broad adoption of the CalDAV protocol, and a future where users can select the calendaring and scheduling application that best suits their needs, rather than being forced to use the (often clunky) client that works with their organization's calendar server.

Joe Presbrey has developed a WebDAV to AFS gateway. The implementation creates a per-user WebDAV server, and uses mod_kerberos for authentication. This allows files to be directly edited in a user's AFS file space. Evaluations of alternate implementation approaches are also described.

The Internet Engineering Task Force (IETF) has approved "HTTP Extensions for Distributed Authoring and Versioning (WebDAV)" as Proposed Standard RFC 4918. This is a new revision of the core WebDAV protocol specification (RFC 2518), which corrects errors in the original specification and includes improvements based on interoperability experience. Current and new implementations of WebDAV should be updated to be consistent with this new specification. An appendix of RFC 4918 provides a detailed descriptions of changes between it and RFC 2518. Congratulations to Lisa Dusseault, Julian Reschke, Geoff Clemm, Cullen Jennings, Elias Sinderson and Jim Whitehead for their hard work on this specification!

The Internet Engineering Task Force has approved "Calendaring Extensions to WebDAV (CalDAV)" as Proposed Standard RFC 4791. This is the core CalDAV protocol specification, and provides a standard way to remotely access and manage calendars. It builds upon the capabilities provided by the WebDAV protocol. This is a tremendous accomplishment, completing an over 10 year long effort by the Internet standards community to develop a remote calendar access protocol. Congratulations to Lisa Duseault, Cyrus Daboo, and Bernard Desruisseaux for their hard work over many years on this specification!

In a similar trend, application specific storage is also supporting WebDAV. Sun has a storage product called Honeycomb that only supports WebDAV or an application programming interface (API) to access data, and does not support traditional lower-level protocols such as NFS and CIFS. Kodak has recently announced they will sell Honeycomb (StorageTek 5800) as Carestream, a picture archiving and communications system for the medical market. Also for archival storage, Archivas Cluster (ArC) is a distributed storage platform designed to support multi-petabyte archives that supports WebDAV (as well as traditional protocols).

The Amazon Simple Storage Service (S3) is an inexpensive web-based storage system that uses a RESTful, S3-specific API for storage. Stefan Eissing crisply summarizes the S3 interface, and discusses design decisions made by S3 and WebDAV. Jungle Disk provides a WebDAV to S3 conversion service, acting as a WebDAV server on your local machine. Similarly, S3DAV also provides a WebDAV interface to an S3 storage account, allowing S3 contents to be accessible via all WebDAV clients, including file system mappers.

Interarchy is a file transfer utility for the Macintosh that, in its 8.2 release, supports WebDAV, as well as the Amazon S3 storage system.

October 4, 2006
