-The onem2m resource tree according to the procedures documented in
-TS0001: OneM2M Functional Architecture, and TS0004: OneM2M Service
-Layer Core Protocol Specification. The two official methods to
-access the data tree are HTTP and CoAP. Typically, applications
-access the data tree with HTTP using the procedures outlined
-in TS0009 OneM2M HTTP Protocol Bindings. And, again, typically,
-devices or things access the data tree using CoAP using the
-procedures outlined in TS0008 OneM2M CoAP Protocol Bindings.

+The Internet of Things Data Management (IoTDM) on OpenDaylight
+project is about developing a data-centric middleware
+that will act as a oneM2M compliant IoT Data Broker and enable
+authorized applications to retrieve IoT data uploaded by any
+device. The OpenDaylight platform is used to implement the oneM2M
+data store which models a hierarchical containment tree, where each
+node in the tree represents an oneM2M resource. Typically, IoT
+devices and applications interact with the resource tree over
+standard protocols such as CoAP, MQTT, and HTTP.
+Initially, the oneM2M resource tree is used by applications to
+retrieve data. Possible applications are inventory or device
+management systems or big data analytic systems designed to
+make sense of the collected data. But, at some point,
+applications will need to configure the devices. Features and
+tools will have to be provided to enable configuration of the
+devices based on applications responding to user input, network
+conditions, or some set of programmable rules or policies possibly
+triggered by the receipt of data collected from the devices.
+The OpenDaylight platform, with its rich unique cross-section of SDN
+capabilities, NFV, and now IoT device and application management,
+can be bundled with a targeted set of features and deployed
+anywhere in the network to give the network service provider
+ultimate control. Depending on the use case, the OpenDaylight IoT
+platform can be configured with only IoT data collection capabilities
+where it is deployed near the IoT devices and its footprint needs to be
+small, or it can be configured to run as a highly scaled up and
+out distributed cluster with IoT, SDN and NFV functions enabled
+and deployed in a high traffic data center.
