is now operational. This just came in from Dennis Hamilton,
and will be of interest to DKR developers. (I highlighted
some of the most interesting ones.)

Here's a quick rundown on where WebDAV (IETF RFC 2518) is in terms of
implementation and deployment. The Microsoft implementation of Web
uses WebDAV (along with two other protocols), so there is a large
complex of
desktops applications, proprietary or not, ready and able to
with WebDAV repositories.

As you can see, the spread of implementations and approaches is very
and growing.

State of Adoption Report

January 20, 2000

It has been a little less than a year since the WebDAV Distributed
Protocol, RFC 2518, was issued by the IETF. I'm very pleased to report
in that time, there has been very strong adoption of the WebDAV
Due to the hard work of the members of this working group, and the
who have written and deployed WebDAV applications, there are now
of people every day who get useful work done using the WebDAV protocol.
Over the next few years, we'll see this number increase into the
as WebDAV technology diffuses broadly into the platforms, programs, and
devices we use on a daily basis, and as people better learn when and how
use WebDAV. Furthermore, as efforts like Advanced Collections, DASL,
Delta-V expand the capabilities of WebDAV, they open up new applications
audiences, leading to yet more users of the protocol. Though WebDAV
adoption has already been strong, in many respects we are just at the
beginning of a long, 20+ year long arc for this protocol.

The purpose of this report is to highlight where WebDAV adoption stands
today by listing clients and servers that support WebDAV. Though WebDAV
devotees will already know much of this information as individual items,
most people are surprised when they see it all put together in one place

there is more here than people expect.  This report lists 10 client
applications, 2 publically available client API libraries, 17 WebDAV
(12 class-2, 5 class-1), and 2 WebDAV-enabled Web storage sites.  These
applications run on a range of platforms, with client support for
Unix, and MacOS, and server support for Windows and Unix. WebDAV
from strong commercial and open source development, showing that the
protocol has a broad spectrum of support beyond any one company or
institution.  Finally, the WebDAV-enabled storage sites are gaining
rapidly, with one site, My Docs Online, currently adding 500 new WebDAV
users a week.

A surprise for WebDAV was the emergence of the Web storage site as a strong adoptor of WebDAV technology. These sites typically offer 20 Meg of storage for free, and the ability to share files with other users of the site. Access to files is via a Web interface, or via WebDAV. The ease of access to remote Web sites provided by Web Folders is motivating adoption of WebDAV by many storage sites. This, in turn, is introducing WebDAV to a large, new audience.

Sharemation http://www.sharemation.com/ The first WebDAV-enabled storage site, offering 20 Meg of storage, non-DAV versioning, DASL support. Uses the Xythos Storage Server.

My Docs Online! http://www.mydocsonline.com/ Also offering 20 Meg of storage. Currently with over 3,000 WebDAV users after just six weeks of offering WebDAV capability. Apparently there would be more WebDAV users, except there are recurring reports of difficulty accessing WebDAV capability through legacy, non-HTTP/1.1 compliant proxies. MyDocsOnline uses a modified version of Apache mod_dav.
