6.2 Identifier of an object instance

The TR-069 [4] specification permits objects to have multiple object instances where each object instance is contained within the objectPath attribute of the Resource within the context of the Resource's objectId as defined in clause 7.1.

In order to allow the AE or CSE that originated the request that manipulates a Resource to easily align the M2M Service Layer with the Resource's external technology identifier, the value of the object instance "{i}" should be a part of the identifier of the Resource in the M2M Service Layer where possible. For example if the [areaNetwork] resource has an object instance identifier of "Device.X_oneM2M_org_CSE.1.M2MareaNetworkDevice.[foo]" then the M2M Service Layer Resource should be identified using the object instance of the underlying technology (e.g. "/foo" for the Resource areaNetwork).
