HISTORIC: This page is not kept up to date. W3C currently does not have an Activity on Web Characterization. The page is made available to preserve information on the results of the Web Characterization Activity.


This is the homepage of the W3C Web Characterization Activity, part of the W3C Architecture domain. The purpose of the Web Characterization Activity is to characterize the Web, develop real world test scenarios, and to provide information for the Web community how the Web is currently being used and anticipated use in the near future.

Highlights:

Nearby you can find the HTTP-NG Activity where the Phase I of this Activity was carried out.

Frequently Asked Questions

Part of the function of the WCA is to help other W3C working groups answer specific questions about the Web and Web technologies. Below are some of the answers we have provided in the past. The group is in the process of actively receiving solicitations for other W3C groups during the April 1999. We'll be posting these results over the summer 1999. Stay tuned.

Mailing List

Discussion of the Web Characterization Activity takes place on the www-wca@w3.org mailing list (Archives). You MUST be subscribed in order to post to this mailing list! Follow these shortcuts to quick subscribe or quick unsubscribe or see the information on mailing lists for more details.

The WCA Request Tracking Forum

The model behind WCA is to provide a link between people with lots of log files and people who are interested in finding out what the Web looks like. In order to track and maintain a user friendly and efficient interface to the various questions and requests for information about the Web, we have built a tool which we call ETA to help us.

The WCA forum is the place where you should ask your questions regarding the Web - email notification will automatically be sent to the <www-wca@w3.org. That is, if you are subscribed (which you should be anyway) then you will get mail there when things happen. Of course, these mails can start discussions that can trigger other questions and so on.

In order for you to participate, you MUST sign in to the system. This is so that we can see who has created the requests and what their email address is. Of course, the privacy policy is exactly the same for our mailing lists - we don't hand out any contact information whatsoever.
