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:

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.

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.
