--- <h1>General information</h1>
+++ <h1>What is?</h1>
+++ <h2>Apache Cocoon</h2>
+++
+++ <p>Apache Cocoon is a <a
href="http://www.springframework.org";>Spring-based</a>
+++ framework built around the concepts of separation of concerns and
+++ component-based development.</p>
+++
+++ <p>Cocoon implements these concepts around the notion of <strong>component
+++ pipelines</strong>, each component on the pipeline specializing on a
particular
+++ operation. This makes it possible to use a Lego(tm)-like approach in
building
+++ web solutions, hooking together components into pipelines, often without any
+++ required programming.</p>
+++
+++ <p>Cocoon used as web framework is "web glue for your web application
+++ development needs". It is a glue that keeps concerns separate and allows
+++ parallel evolution of all aspects of a web application, improving
development
+++ pace and reducing the chance of conflicts. In particular it makes it easy to
+++ support multiple output formats, offers continuation based web controller
+++ implementations and comes with a JSR-168 compatible Portal
implementation.</p>
+++
+++ <h2>Cocoon blocks</h2>
+++
+++ <p>A block is the unit of modularization (Eclipse uses the term plugins,
OSGi
+++ bundles) in Cocoon. Everything that goes beyond that what Cocoon provides
in its
+++ core modules (Spring integration, sitemap and pipeline implementation) is
+++ provided as block. Every custom Cocoon application is developed as block. A
+++ block <em>can</em> provide following features:</p>
+++
<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>sitemap services by provide pipelines that can be called by a special
+++ purpose protocol (<tt>block:</tt>) as a special servlet service</li>
+++ <li>general servlet services (<em>any</em> servlet can be managed by the
Cocoon
+++ blocks framework)</li>
+++ <li>component services (Spring beans, Avalon services/components)</li>
+++ <li>a container for classes and resources</li>
+++ </ul>
+++
+++ <p>A block is packaged as Java archive (jar) following certain
conventions.</p>
