[Fiware-iot] ETSI M2M Definitions

Dear all,
As decided last Wednesday in the online meeting, I provide you the ESTI M2M Definitions document (see the 00004v030.pdf attachment).

I find that there are two macro differences between the IoT definitions in Fi-ware and in the ETSI M2M document:


 *   in the ETSI M2M Definitions there are the definitions of both Local and Network Applications (e.g. Devices Applications and Gateway Applications, that are local, and Network Applications).


 *   in the ETSI M2M Definitions the concept of the Area Network, that connects the M2M Devices to M2M Gateways, is defined while this definition in the IOT is missing.

The other IoT definitions are similar to the ETSI M2M ones.

For reference I include here two figures from the M2M Functional Architecture document that describe the functional blocks in the M2M Architecture and can be compared with the figure 1 in the FI-Ware_DoW_Extract_IoT_B1 document:
