<h1>General information</h1>

<ul>
<li>Apache Cocoon is a web development framework built around the concepts of
component-based web development and separation of concerns, ensuring that people
can interact and collaborate on a project without stepping on each other toes.
</li>
<li>Cocoon implements these concepts around the notion of <strong>component
pipelines</strong>, each component on the pipeline specializing in a particular
operation (usual pipeline uses a Generator, Transformers and a Serializer). This
makes it possible to use a Lego(tm)-like approach in building web solutions,
hooking together components into pipelines without requiring programming.</li>
<li><strong>Advanced Control Flow</strong>: continuation-based page flow
hides
the complexity of request/response processing and is cleanly separated from the
view and data components.</li>
<li>Cocoon is open source software (based on the <a href="daisy:421">Apache
Software License</a>).</li>
<li>Cocoon does not duplicate efforts but tightly integrates many technologies.
</li>
<li>Cocoon is in use at many live sites and on many company networks.</li>
<li>Cocoon has a strong community, with many active developers and more than
<a href="daisy:630">plenty of active committers</a>!</li>
<li>There is free support from the thousands of people on our
<a href="http://cocoon.apache.org/community/mail-lists.html">mailing lists</a>
and commercial support is available from various companies and consultants.
</li>
<li>There are many Cocoon sessions at different conferences:
<ul>
<li><a href="http://www.orixo.com/events/gt2003/">Cocoon GetTogether</a></li>
<li><a href="http://apachecon.com/">ApacheCon</a></li>
<li><a href="http://cocoon.ifs.tuwien.ac.at/">Austrian Cocoon Day</a></li>
<li><a href="http://www.wjax.de/">WJAX</a></li>
<li><a href="http://www.jax2003.de/">JAX</a></li>
</ul>
</li>
<li>To get started see the <a href="daisy:424">"first steps" documentation
track</a>. Basically you only need to
<a href="http://cocoon.apache.org/mirror.cgi">download</a> Cocoon, unpack it and
follow the simple INSTALL.txt instructions. A minimal version of the Jetty
servlet container is included with Cocoon.</li>
</ul>

<h1>Usage scenarios</h1>

<p>As you would expect, all of these scenarios can be combined.</p>

<ul>
<li>Dynamic multi-channel web publishing (see below for the possible datasources
and output formats)</li>
<li>Create static content (automatically) by separating data from view</li>
<li>Offline generation modes with Cocoon's own
<a href="userdocs/offline/">offline facilities</a>: command-line interface
(CLI), ant task, bean. Also with <a href="http://forrest.apache.org/">Apache
Forrest</a> which utilises Cocoon.</li>
<li>Dynamic document preparation with
<a href="http://forrest.apache.org/">Apache Forrest</a>, the '<tt>forrest
run</tt>' mode. Use many different data input formats, see the transformed
result immediately in the browser.</li>
<li>Advanced web applications with J2EE integration (with separation of your
data, the view and the <a href="daisy:517">flow logic</a> --&gt; this really
means you can change one of the parts without touching another)</li>
<li>Develop your company portal using the Cocoon Portal framework</li>
<li>Support multiple clients, layouts and languages (i18n) without code
duplication</li>
<li>Integrate Cocoon with your existing web applications or use it to put a
better face on them (page scraping)</li>
<li>Add full-text search to any datasource that can be converted to XML (see
below)</li>
<li>Use Cocoon as the base for Enterprise Application Integration (EAI)</li>
<li>Use Cocoon as the base for your Content Management System (CMS) (see
<a href="http://cocoon.apache.org/lenya/">Apache Lenya</a> for a Cocoon based
CMS)</li>
<li>Use Cocoon for producing mobile content (mobile phones, pdas)</li>
<li>Datawarehouse reporting across multiple formats (see xReporter)</li>
</ul>
