If you don't want "this" to happen in the future, I would suggest that you
direct comments about the ICE protocol to the ICE Authoring Group rather
than posting broadsides on your web site and public lists. Admittedly,
several members of the ICE AG happened to be on the list, so we've been
able to engage in this educational dialogue, but more direct communication
is probably more productive.

You mean, the way you and Netscape contacted the ICE AG regarding the RSS
effort?

I certainly agree with the idea that standards effors should be widely
communicated and open to all interested parties. The ICE AG has made
contact information as public as it can (embedded in the spec, press
releases, etc., for two years), and had a large number of companies
involved in the process, including major content and technology companies.
I am sorry that our marketing efforts were apparently insufficient to get
you involved in the effort, and that in the two years since the initial
public announcements, and hear and a half since the submission of 1.0 to
the W3C, that we've been unable to inspire you to contact us.

To be honest, we targeted companies that are in business of producing,
syndicating, or consuming content, not (at the time) scripting language
vendors. I would have thought that when you repositioned your company as a
"content management and syndication" company you would have contacted
existing relevant standards bodies.

That being said, the current Authoring Group (in alphabetical
order) consists of:

Sasha Aickin, Plumtree Software, Michael Branch, Vignette Corporation, Jay
Brodsky, Tribune Media Services - Implementation Sub-Committee Chairman,
Phil Gibson, National Semiconductor, Jack Gudenkauf, Microsoft, Martin
Hardee, Sun Microsystems - Standards Outreach Sub-Committee Chairman,
Bruce Hunt, Adobe Systems - Vice Chairman, Brad Husick, Vignette
Corporation - Marketing Sub-Committee Chairman (non-voting), Sami Khoury,
What U Want, Inc., Daniel Koger, Herrick Douglass, Erik Leckner, Seagate
Technology, Inc., Dr. Richard Martin, Active Data Exchange, Inc., Nathan
Pride, Wavo Corporation, Laird Popkin, Sotheby's Holdings - Chairman,
Mondhipa Ratnarathorn, Fresher Information Corp., and Adam Souzis, Kinecta
Corp. (formerly ShiftKey Inc.).

And there are two dozen or so in the ICE Network (which includes
participants who aren't in the Authoring Group), such as Documentum,
ArcadiaOne, Intershop, and Intervu.

I trust that you are familiar enough with the market to pick out which
ones are direct competitors of Vignette's.

Detailed information on the standard and membership in the ICE Network is
at http://www.icestandard.org.

I am confused about how you see RSS as being better suited to individual
content creators than ICE; from what I can see, the reverse appears to be
true. RSS requires content syndicators to be in the web site business
(operate a web site with a persistent internet connection with enough
bandwidth to transmit content to all subscribers at any time, sell
advertising, etc.). ICE syndicators can create content offline and need
only be online to transmit the content (e.g. to a publisher) and can use
scheduling to manage bandwidth consumption.

This doesn't make RSS a bad protocol, just one that targets a more limited
application space than ICE.

As I said before, the "simple" model works fine for web sites who want to
share headlines to drive traffic, and it's a case that ICE supports. I
think that your input could be valuable in making sure that we have kept
that "simple case" as simple as possible, and in communicating that fact
to people who would otherwise misunderstand the ICE standard.

I think that Jonathan Eisenzopf's article on RSS at
http://www.webtechniques.com/archives/2000/02/eisenzopf/ portrays the
relationship between the protocols appropriately: "It's important to note
that while RSS is capable of syndicating content headlines, there are
other XML formats like XMLNews and ICE that are better suited for handling
larger syndication systems." It's an insightful comment, particulary given
that Reuters recently launched their online content syndication service,
based on ICE and an XML news format. The announcement is at
http://www.reuters.com/aboutreuters/newsreleases/2000/XMLnews.html.

Given that ICE does everything that RSS does, and was published (and
implemented) well before the RSS effort started, I would have preferred
coordinating from the start. Let's make up for lost time; I'd like to open
exploration of whether there's a means of unifying the two standards, so
that rather than picking between RSS and ICE, there could be a gradiation
of capabilities of a unified syndication standard that addresses the full
range of content syndication scenarios.

Let's discuss how to proceed. You have 
my contact information. I suspect that the rest of the people on this list
would appreciate it if we continued this discuss offline.
