<h2><a name="intro">Introduction</a></h2>
|
|
|
|
<p>Extensible Markup Language (XML) is a simple, very flexible text format
|
|
derived from SGML (ISO 8879). Originally designed to meet the challenges of
|
|
large-scale electronic publishing, XML is also playing an increasingly
|
|
important role in the exchange of a wide variety of data on the Web and
|
|
elsewhere.</p>
|
|
|
|
<p>This page describes the work being done at W3C within the XML Activity,
|
|
and how it is structured. Work at W3C takes place in <i>Working Groups</i>.
|
|
The Working Groups within the XML Activity are listed below, together with
|
|
links to their individual web pages.</p>
|
|
|
|
<p>You can find and download formal technical specifications here, because we
|
|
publish them. This is <em>not</em> a place to find tutorials, products,
|
|
courses, books or other XML-related information. There are some links below
|
|
that may help you find such resources.</p>
|
|
|
|
<p>You will find links to W3C Recommendations, Proposed Recommendations,
|
|
Working Drafts, conformance test suites and other documents on the pages for
|
|
each Working Group. Each document also contains email addresses you can use
|
|
to send comments or questions, for example if you have been writing software
|
|
to implement them and have found problems or errors.</p>
|
|
|
|
<p>Please do <em>not</em> send us email asking us to help you learn a
|
|
language or specification; there are plenty of resources online, and the
|
|
people editing and developing the specifications are very busy. We
|
|
<em>are</em> interested in technical comments and errata.</p>
|
|
|
|
<p>If your organization would like to join the W3C, or if you would like to
|
|
participate formally in a working group (and have the necessary resources to
|
|
attend meetings), you can read more <a href="/Consortium/">about the
|
|
Consortium</a>.</p>
|
|
|
|
<h2><a name="wgs">Working Groups</a></h2>
|
|
|
|
<p>There is more detail about each of these Working Groups in the <a
|
|
href="Activity">Activity Statement</a> and also on the individual Working
|
|
Group public web pages.</p>
|
|
|
|
<p>Most Working Groups have both a public web page and another more private
|
|
one that is only accessible to W3C Members. The private page has telephone
|
|
numbers, schedules for meetings and conference calls, links to internal
|
|
editing drafts, and other administrative information.</p>
|
|
<!--* removed the following note because I can't find the page any
|
|
* more; I think the nearest is
|
|
* http://cgi.w3.org/MemberAccess/
|
|
*
|
|
* <p>If you find you can't get to the private pages
|
|
* but believe you should
|
|
* be able to do so, you can
|
|
* <a href="/MemberAccess/">apply for access</a>.</p>

<h3><a name="xml-cg">XML Coordination Group</a></h3>
|
|
|
|
<p>The membership of this group is the Chairs of the individual Working
|
|
Groups. Its role is to provide a forum for coordination between the Working
|
|
Groups of the XML Activity, and between the XML Activity and other parts of
|
|
W3C, and between the XML Activity and other organizations.</p>
|
|
|
|
<p>This group does not produce specifications, so does not have a public page
|
|
of its own. You can read the <a href="/2003/09/xmlap/xml-cg-charter">XML CG
|
|
Charter</a>, and there is more information about the XML CG in the <a
|
|
href="Activity">Activity Statement</a>. There is is also a <a
|
|
href="Group/">member-only page</a>.</p>
|
|
|
|
<h3><a name="core-wg">XML Core Working Group</a></h3>
|
|
|
|
<p>The mission of the XML Core Working Group is to develop and maintain the
|
|
specifications for XML itself and closely related specifications such as
|
|
Namespaces in XML, the XML Information Set, and XInclude.</p>
|
|
|
|
<p>You can read the <a href="Core/">XML Core Working Group Public Page</a>
|
|
and the <a href="/2005/02/xml-core-wg-charter.html">XML Core Working Group
|
|
Charter</a>, and there is also a <a href="Group/Core">member-only
|
|
page</a>.</p>
|
|
|
|
<h3>XSLT Working Group</h3>
|
|
|
|
<p>The <a name="xsl-wg">XSLT Working Group</a> is responsible for
|
|
XSL Transformations (XSLT) and a number of supporting specifications.</p>
|
|
|
|
<p>You can read the <a href="/Style/XSL/">XSLT Working Group Public Page</a>
|
|
which links to their <a href="/2003/09/xmlap/xsl-wg-charter.html">Charter</a>
|
|
and to their <a href="/Style/XSL/Group/">member-only page</a>.</p>
|
|
|
|
<h3>XPPL Working Group</h3>
|
|
<p>The <a name="xppl-wg">XML Print and Page Layout Working Group</a>
|
|
is responsible for the XSL-FO formatting language.</p>
|
|
|
|
<p>You can read the <a href="XPPL/">XML Print and Page Layout Public Page</a>
|
|

|
|
Charter</a>, and there is also a <a href="Group/XPPL">member-only
|
|
page</a>.</p>
|
|
|
|
<h3>The Efficient XML Interchange Working Group</h3>
|
|
|
|
<p>The <a name="exi-wg">Efficient XML Interchange Working
|
|
Group</a> is responsible for developing ways to exchange XML documents in
|
|
ways that are as efficient as is practical without compromising the
|
|
interoperability of XML itself. It also continues the work of the <a
|
|
href="#binary-wg">XML Binary Characterization Working Group</a>. This Working
|
|
Group is <em>not</em> about producing a closed, proprietary or obfuscated
|
|
“binary XML ”—The W3C is all about increasing
|
|
interoperability!</p>
|
|
|
|
<p>You can read the <a href="EXI">Efficient XML Interchange Working Group
|
|
Public Page</a> and their <a
|
|
href="/2005/09/exi-charter-final.html">Charter</a>; there is also a <a

|
|
|
|
<h3><a name="processing-wg">XML Processing Model Working
|
|
Group</a></h3>
|
|
|
|
<p>The XML Processing Model Working Group is working on defining a scripting
|
|
language for XML: that is, a way to specify what operations should be
|
|
performed on an XML document and in what order.</p>

|
|
<p>You can read the <a href="Processing/">XML Processing Model Working Group
|
|

|
|
purposes.</p>
|
|
|
|
<h3><a name="linking-wg">XML Linking Working Group</a></h3>
|
|
|
|
<p>The charter of the XML Linking Working Group has expired, and the group is
|
|
not currently active. When still active, it was working on hypertext links
|
|
for XML. This includes the XML Linking Language (XLink) and the XML Pointer
|
|
Language (XPointer).</p>
|
|
|
|
<p>You can read the deprecated <a href="Linking">XML Linking Working Group
|
|
Public Page</a>. There is also a <a href="Group/Linking">member-only
|
|
page</a>.</p>
|
|
|
|
<h3><a name="query-wg">XML Query Working Group</a></h3>
|
|
|
|
<p>The XML Query Working Group is working on the XML Query Language, a way to
|
|
provide flexible query facilities to extract data from real and virtual XML
|
|
documents on the Web. This includes publication of XQuery and also XPath, in
|
|
conjunction with the <a href="/Style/XSL/">XSLT Working Group</a> (part of the
|

<h2><a name="events">Upcoming events</a></h2>
|
|
|
|
<p><a href="http://www.xmlprague.cz/2011/index.html">XML Prague</a>,
|
|
the leading XML-specific conference in Europe,
|
|
was in 2011, in... er, yes, in Prague.</p>
|
|
|
|
<p>The leading conference relating to theoretical topics on markup,
|
|
as well as on practical applications of XML, is of course
|
|
<a href="http://www.balisage.net/">Balisage</a>, in Montreal;
|
|
this year (2011) the Balisage markup conference also has an associated

|
<a href="http://www.balisage.net/interchange/">XML Document Interchange</a>.
|
|
There is a registration discount for W3C Members.</p>

<h2><a name="resources">Other Resources</a></h2>
|
|
|
|
<p>There are so many resources related to XML that we can't possibly list
|
|
them all here. This is a <em>good</em> thing, because it means XML is a
|
|
success! In addition to a <a name="oldevents"
|
|
href="hist2002">history of the development of XML at W3C</a>, there is an
|
|
extensive index at the <a href="http://xml.coverpages.org/">Cover Pages</a>,
|
|
maintained by Robin Cover. The individual Working Group public web pages may
|
|
have links to specific resources. There are Usenet newsgroups (e.g. <a
|
|
href="news://comp.text.xml">comp.text.xml</a>) and public mailing lists (e.g.
|
|
<a href="http://lists.xml.org/archives/xml-dev/">xml-dev</a>).</p>
