Model schemas for addressing resources (or) Generate the Feed with myContentHandler

Addressing a resource includes specifying the model to which the resource is associated. To do this, you specify a schema.

There is a schema defined for each model that the remote model SPI supports:
•    For addressing a resource in the content model: cm
•    For addressing a resource in the navigation model: nm
•    For addressing a resource in the layout model: lm
•    For addressing a resource in the portlet model: pm

Furthermore, you need to specify the resource of the model itself, as described in the following resource addressing specification:
model-uri = "cm:" page-oid |
            "nm:" navigationnode-oid |
            "lm:" [layoutnode-oid "@"] page-oid |
            "pm:" portlet-oid ["@" page-oid

The meanings of the syntax elements are as follows:

page-oid    :
This is the portal object ID of a content page. When you address portlet model resources, this is required for portlet windows, but it must not occur for any other portlet model resource identification.

navigationnode-oid   :  This is the object ID of a navigation model node.
layoutnode-oid         : This is the object ID of a layout model node.
portlet-oid                : This is the object ID of a layout control, portlet window, portlet entity, or
                                  portlet definition.
oid           :  This is the serialized string that represents a portal object ID. This is URI-escaped with UTF-8 encoding. The character @ is also escaped by using %40. You can also use unique names instead of object IDs. Unique names also have to be URI-escaped, and the @ character must be escaped. Note that every object ID has the defined scheme 'oid:'.

Note that the model schemes are mandatory for ambiguity reasons. For example content and navigation nodes currently have got the same object IDs.

Example 1: To obtain a feed of the root node of content model, that is the content node with the unique name wps.content.root, send an HTTP GET request to the following URL:
/wps/mycontenthandler?uri=cm:oid:wps.content.root

Example 2: To obtain a feed of the layout node with the object id '_7_0830M4HTFF0SHFCQ_2BV' on the content page with the object id '_6_0830M4HTFF0SHFCQ_4D', send an HTTP GET request to the following URL:
/wps/mycontenthandler?uri=lm:oid:_7_0830M4HTFF0SHFCQ_2BV@oid:_6_0830M4HTFF0SHFCQ_4D
