28  * <P>
29  * The <CODE>PortletRegistryService</CODE> interface represents all
30  * portlets and portlet applications available in the portal. It is accessed
31  * by the datastore layer to get information about the portlets and
32  * portlet applications.
33  * </P>
34  * <P>
35  * The interfaces defined in this package represent an abstract object
36  * model (OM) that is applicable for different implementations.
37  * The abstract OM defines only how the data is stored and accessed
38  * in the memory. Each implementation can store the data in different ways.
39  * </P>
40  * <P>
41  * This abstraction layer helps to generalize the portlet container from
42  * special implementations like data storage and moreover it is not bound
43  * to a special Application Server.
