 The Content Repository API Layer is split into two major sections.

 <li>A number features of a content repository, that have been removed from the JSR-170
specification since they are difficult to implement on existing non-java-based content repositories

+  <title>Levels of Content Repository API for Java Technology (JSR-170)</title>
+ </properties>
+ <body>
+
+<section name="JSR-170 Levels">
+<p>
+The Content Repository API for Java Technology (JSR-170) is split into different
+Levels of compliancy, to allow Repository Vendors to gradually adopt JSR-170
+and to avoid that the overhead is unnecessarily high for repository vendors
+that only want to expose portions of their repository functionality through
+a JSR-170 compliant Interface.
+</p>
+<p>
+JSR-170 specifies a Level 1, a Level 2 and a set of advanced repository 
+feature blocks. Jackrabbit is fully JSR-170 compliant and therefore
+supports Level 1, Level 2 and all the optional blocks.
+</p>
+</section>
+
+<section name="Level 1 : Ease of Adoption, Covering many usecases">
+<p>
+The Scope of Level 1 of JSR-170 to cover a large number of simple 
+Applications, that need to search repositories and need to read 
+from repositories.
+Level 1 specifies a read-only API that allows to 
+introspect Node and Property-types and offers hierarchical
+read access to content stored in a repository.
+</p>
+<img src="../../images/arch/level-1.jpg"/>
+<p>
+Level 1 of JSR-170 is geared to allow people to write 
+applications such as search and display Portlets, 
+CMS-Templates, Reports, Exports or other applications 
+that harvest, search, present or display information 
+from one or multiple repositories.
+</p>
+</section>
+
+<section name="Level 2 : Writeable Repository">
+<p>
+Level 2 of JSR-170 specifies all the writing 
+capabilities need to bi-directionally interact with a
+content repository in a fine and coarse grained 
+fashion.
+</p>
+<img src="../../images/arch/level-2.jpg"/>
+<p>
+Applications written against Level 2 of JSR-170 include
+management applications or generally speaking any 
+application that generates data, information or content
+for both structured and unstrcutured information.
+</p>
+</section>
+
+<section name="Advanced Options">
+<p>
+On top of Level 1 or Level 2 a number of functional 
+block serve for more advanced repository functionality.
+This includes functions like: Versioning, 
+(JTA) Transactions, Query using SQL, Explicit 
+Locking and Content Observation.
+</p>
+<img src="../../images/arch/level-adv.jpg" />
+<p>
+A fully JSR-170 compliant repository like Jackrabbit
+encompasses all the functionalities and therefore
+lends itself as general purpose, off-the-shelf 
+infrastructure for Content-, Document- and
+Source Code Management or for just about any 
+other application that persists content.
+</p>
