The W3C Ecommerce/Micropayment Activity is now closed.
</H2>
<P>
An major factor in the evolution of the Web is Electronic Commerce: the ability
to buy, sell, and advertise goods and services to customers and consumers.
One concern in the development of Electronic Commerce on the Web is the trust
that can be placed in the provenance, reliability, security and privacy of
information available from or transferred over the internet. Another concern
is the need for low friction commerce transactions allowing quality and ease
of use for consumers, a key factor the future of Electronic Commerce. The
potential for global electronic commerce is immense; much of this potential
is and will be realized by the continued development of Web technologies.
The World Wide Web Consortium, leading the web to its full potential, is
therefore concerned with the evolution of Electronic Commerce on the Web.
The role of W3C is to focus on core infrastructure technologies for Electronic
Commerce and identify common infrastructure needed in this area. W3C is not
committed for example in specifying banking systems nor schemas for specific
Electronic Commerce applications.
<P>
W3C has closed its Ecommerce and Micropayment Activity, but through the following
activities W3C is committed to key factors for success in the evolution of
Electronic Commerce:<BR>
<UL>
<LI>
The W3C <A href="http://www.w3.org/DSig">XML Signature</A> provides a mechanism
for signing documents and metadata in order to establish who made the statement.
<LI>
The W3C <A HREF="http://www.w3.org/Encryption/2001/">XML Encryption</A> specifies
a process for encrypting/decrypting digital content and an XML syntax used
to represent the encrypted content and information that enables an intended
recipient to decrypt it.
<LI>
The W3C <A HREF="http://www.w3.org/2000/xp/">XML Protoco</A>l goal is to
develop technologies which allow two or more peers to communicate in a
distributed environment, using XML as its encapsulation language, allowing
automated negotiations. The search is on for common ground that can meet
the heavyweight, commercial demands of business to business e-commerce systems,
and at the same time satisfy aesthetic requirements for a lightweight, simple
network protocol for distributed applications.
<LI>
The <A HREF="http://www.w3.org/2001/sw/">Semantic Web </A>is a vision: the
idea of having data on the web defined and linked in a way that it can be
used by machines not just for display purposes, but for automation, integration
and reuse of data across various applications.
<A HREF="http://www.w3.org/Metadata/">Metadata</A> provides a means to make
statements and create machine-readable statements.
<LI>
The <A href="http://www.w3.org/P3P">Platform for Privacy Preferences
Project</A> (P3P) provides communication about data privacy practices between
consumers and merchant sites on the Web as well as enhanced user control
over the use and disclosure of personal information.
<LI>
The <A href="http://www.w3.org/ECommerce/Micropayments/">Micropayment
initiative</A> specifies how to provide in a Web page all the information
necessary to initialize a micropayment and transfer this information to the
wallet for processing.
<LI>
Major W3C common specifications for the Web in areas such as
<A HREF="http://www.w3.org/Protocols/">network protocols</A>,
<A href="http://www.w3.org/UI/">graphical user interface</A>, remain the
basis of Electronic Commerce.

What it is about
</H2>
<P>
An important factor in the growth of the Web is <I>electronic commerce</I>:
the ability to buy, sell, and advertise goods and services to customers and
consumers. The Web is a new communications medium and, like all new media,
requires us to rethink the existing solutions to age-old problems. The World
Wide Web Consortium is concerned with the evolution of the medium itself.
We must both understand the problems and work with our members to contribute
to the solutions. The <B>Electronic Commerce Interest Group</B> is a forum
designed to allow the members to share information with the Consortium staff
and other members about:
<UL COMPACT>
<LI>
Problems they have encountered (and proposed solutions)
<LI>
Priorities (in addressing the problems)
<LI>
Work underway in related areas
<LI>
What role, if any, the Consortium should play
</UL>
<P>
The Interest Group meets three times a year for two years, with meetings
spread across North America, Europe, and Asia/Pacific. There is an on-going
<A HREF="#Join Mailing List">email list</A> associated with the Interest
Group. There is no required resource commitment beyond attendance at any
or all of the meetings, although registration is required for each meeting.
<P>
The Interest Group has no decision-making authority and is strictly advisory
to the W3C staff. Nonetheless, we expect it to be the forum from which we
will draw participants in the design of briefing packages for work related
to Electronic Commerce. It will also serve to help refine the requirement
of any technical work in this area to be undertaken by W3C.
<H2>
Micropayment initiative
</H2>
<P>
The <A HREF="/ECommerce/Activity.html">Electronic Commerce Activity </A>is
currently involved in realizing the opportunities in
<A HREF="/ECommerce/Micropayments/Overview.html">Micropayments</A>, and this
will form the main thrust of the Activity during the next 6 months.
<A HREF="/ECommerce/Micropayments/Overview.html">Micropayments</A> are very
small payments made over the Web for pages that you access. Micropayments
cover transactions which are too small to be economical as credit card
transactions, and can be as little as a fraction of a cent. Micropayments
provide an alternative to subscription and advertising as a source of revenue.

and Content Exchange Protocol proposes a protocol and data format to implement
the shared business rules in the domain of syndicated content, on top of

<A href="http://www.w3.org/Submission/1998/09/">SDML</A>- The Signed Document
Markup Language describes how to structure a complete signed document, with
the material being signed as part of the document. We expect that a web-based
document signature scheme would have to address external documents, also
referenced by URI. SMDL was an important initial contribution to the
<A href="http://www.w3.org/Signature">XML Signature</A> Working Group.

<A href="http://www.w3.org/Submission/1999/02/">UCLP</A> - The Universal

for metadata related to commercial products and companies and that can be
used in identifying and retrieving product data residing across the Internet.
<LI>
<A HREF="http://www.w3.org/Submission/1999/11/">Using P3P for E-Commerce</A>
describes how to use P3P's extensible data schema mechanism to define data
schemas appropriate for e-commerce applications.
<LI>
<A HREF="http://www.w3.org/Submission/1999/05/">XFA</A> - XML Forms
Architecture describes an XML tagset for electronic forms with support for
