+          <H1>Node Type Notation</H1>
+  <P>The Compact Namespace and Node Type Definition (CND) notation provides a compact standardized syntax for defining node types and making namespace declarations. The notation is intended both for documentation and for programmatically registering node types (if you are unfamiliar with JCR node types, you may want to read the general Node Types section first).</P>

+          <H1>Node Types</H1>
+  <P>Each node in a Jackrabbit workspace tree has a node type that defines the child nodes and properties it may (or must) have. Developers can use node types to define a custom content model for their application domain and have Jackrabbit enforce the constraints of that model at the repository level.</P>
+
+<H2><A name="NodeTypes-PrimaryvsMixin"></A>Primary vs Mixin</H2>
+
+<P>There are two categories of node types, <B>primary</B> and <B>mixin</B>. Every node has a primary node type assigned to it upon creation (see <TT>Node.addNode</TT> in the JCR API). In addition, a mixin node type may be added to a node later in its lifecycle (see <TT>Node.addMixin</TT>).</P>
+
+<P>The primary node type of a node usually defines node structure (i.e., allowed and required child nodes and properties) related to the problem domain being modeled. For example, a node used in storing content about business contacts might have the primary type <TT>myapp:Contact</TT> which defines properties such as <TT>myapp:givenName</TT>, <TT>myapp:familyName</TT> and so forth.</P>
+
+<P>Mixin node types usually specify additional properties or child nodes related to a capability being added to the node. These capabilities may include generic repository-level functions as in the case of the built-in mixins <TT>mix:versionable</TT> and <TT>mix:lockable</TT>, for example, or domain-level capabilities such as a (hypothetical) <TT>myapp:Emailable</TT> mixin type that adds the property <TT>myapp:emailAddress</TT> to a node.</P>
+
+<H2><A name="NodeTypes-Inheritance"></A>Inheritance</H2>
+
+<P>Primary node types are arranged in an inheritance hierarchy. Every primary node type must be the subtype of at least one existing node type. The built-in node type <TT>nt:base</TT> serves as the root of this hierarchy. Jackrabbit supports multiple inheritance of node types so node types can have more than one supertype.</P>
+
+<P>Mixin node types do not have to have supertypes.</P>
+
+<P>The JSR 170 specification and the current public review draft of the JSR 283 specification (section 4.7.7) leave it up to the implementation whether e.g. the orderable child nodes setting is inherited from supertypes. Inheritance semantics, especially with multiple inheritance, are non-trivial at best and up to a certain degree arbitrary. Jackrabbit therefore, in compliance with the spec, doesn't support inheritance of node type attributes such as orderable.</P>
+
+<H2><A name="NodeTypes-NodeTypeDefinition"></A>Node Type Definition</H2>
+
+<P>A node type definition has the following attributes:</P>
+
+<UL>
+	<LI><B>Name</B> Every node type registered with the repository has a unique name. The naming conventions for node                     types are the same as for items (i.e., they may have a colon delimited prefix).</LI>
+	<LI><B>Supertypes</B> A primary node type (with the exception of <TT>nt:base</TT>) must extend another node type (and may extend more than one node type). A mixin node type may extend another node type.</LI>
+	<LI><B>Mixin Status</B> A node type may be either primary or mixin.</LI>
+	<LI><B>Orderable Child Nodes Status</B> A primary node type may specify that child nodes are client-orderable. If this status is set to true, then <TT>Node.orderBefore</TT> can be used to set the order of child nodes. Only primary node types control a node's status in this regard. This setting on a mixin node type will not have                     any effect on the node.</LI>
+	<LI><B>Property Definitions</B> A node type contains a set of definitions specifying the properties that nodes of this node type are allowed (or required) to have and the characteristics of those properties (see below).</LI>
+	<LI><B>Child Node Definitions</B> A node type contains a set of definitions specifying the child nodes that nodes of this node type are allowed (or required) to have and the characteristics of those child nodes (including, in turn, their node types, see below).</LI>

If a node of a type that specifies a                         mandatory property is created then any attempt to save that node without adding the mandatory property will fail. Since single-value properties either have a value or do not exist (there being no concept of the null value) this implies that a mandatory single-value property must have a value.

+	<LI><B>Multiple Values Status</B> Whether this property can have multiple values, meaning that it stores an array of values, not just one. Note that this &quot;multiple values&quot; flag is special in that a given node type may have two property definitions that are identical in every respect except for the their &quot;multiple values&quot; status. For example, a node type can specify two string properties both called X, one of which is multi-valued and the other that is not. An example of such a node type is <TT>nt:unstructured</TT>.</LI>

Note that this                         is possible because Jackrabbit supports multiple inheritance among node types and that each node still has one and only one primary node type.</LI>

+          <H1>Object Content Manager</H1>
+  <P>The main component in the OCM framework is the ObjectContentManager. It converts an object graph into JCR nodes and properties and vice versa. The ObjectContentManager is always associated with a JCR Session. It is used to retrieve, create, update and delete objects from a JCR content repository. Usually there is one ObjectContentManager per user session.</P>
+
+<P>This page describes how an ObjectContentManager is working and how it can be initialised in your applications. </P>
+
+<H2><A name="ObjectContentManager-HowdoestheObjectContentManagerwork%3F"></A>How does the Object Content Manager work ?</H2>
+
+<P>Thanks to a Mapping Descriptor, the ObjectContentManager is able to use the appropriate mapping strategy for each persistent object (pojo). The Mapping Descriptor contains one Class Descriptor per persistent class. Each Class Descriptor contains mapping information for the corresponding class attributes.</P>
+
+<P>In the point of view implementation, the Mappring Descriptor is a java object injected into the ObjectContentManager (see the interface org.apache.jackrabbit.ocm.mapper.Mapper). Right now, there are 2 different Mapping Descriptor implementations:</P>
+
+<UL>
+	<LI>Annotation : each persistent object is annoted in order to provide to the ObjectContentManager all the required information on its mapping strategy (see the class org.apache.jackrabbit.ocm.mapper.impl.annotation.AnnotationMapperImpl).</LI>
+	<LI>XML configuration file : the class descriptors are defined in one or more XML config files used by the ObjectContentManager when it is instantiated (see the class org.apache.jackrabbit.ocm.mapper.impl.digester.DigesterMapperImpl).</LI>
+</UL>
+
+
+<P>For a business developer, it is not necessary to know how the ObjectContentManager is using the Class Descriptors. He has to make only a choice between annoted classes or XML files. Below, you can see how to setup correctly an ObjectContentManager. </P>
+
+<H2><A name="ObjectContentManager-HowdoesanobjectispersistedintoaJCRrepository%3F"></A>How does an object is persisted into a JCR repository ?</H2>
+
+<P>In all cases, a persistent object (a pojo) is mapped into a JCR node and its fields are mapped into subnodes or properties depending on their types.</P>
+
+<P>There are 3 &quot;field types&quot;:</P>
+
+<UL>
+	<LI>Atomic fields<BR>
+    Primitive data types and simple objects (String, Long, Double, ...) . Those fields are mapped into JCR properties. </LI>
+</UL>
+
+
+<UL>
+	<LI>Bean fields<BR>
+    One class can contain an 1..1 association to another bean. In this case, the field is a custom object. Those fields are mapped into JCR subnodes or a referenced node. </LI>
+</UL>
+
+
+<UL>
+	<LI>Collection fields<BR>
+    One class can contain an 1..n association to a collection of beans (or Map). Those fields are mapped into a collection of JCR subnodes or a collection of referenced nodes. It is also possible to map a java collection into a multivalue property. </LI>
+</UL>
+
+
+<P>The Mapping descriptor contains also information on inheritances, interface mapping strategy, lazy loading, custom converter, cache strategy, etc. </P>
