Contents
Terminology
- ACL: Access Control List. List of permissions attached to an object, specifying which entity of a system is granted access to it.
- Software package: A binary file containing software and metadata that can be sent to an M2M device to update one of its software components
Functional requirements
- The M2M application meta-model MUST allow the description of the different parts an M2M application is made of.
- It MUST allow the description of the data that can be exchanged between a device and a server.
- It MUST allow the description of the device management capabilities provided by an M2M application.
- It MUST allow the description of the different components an M2M application is made of.
Data Management
- The M2M application meta-model SHOULD allow to structure data elements hierarchically.
- The M2M application meta-model MUST allow to associate a type to data elements.
- The M2M application meta-model MUST support the following primitive types: string, integer, double, date, boolean, byte array.
- The M2M application meta-model SHOULD allow to define constraints for the data, such as: range, max length, ...
- The M2M application meta-model SHOULD allow to indicate the protocol to use when exchanging a given data element.
- The M2M application meta-model SHOULD allow to associate configuration parameters to protocols
- The M2M application meta-model SHOULD allow to associate an history policy (keep all, keep last, keep on change...) to a data element.
- The M2M application meta-model SHOULD allow to associate ACLs to data elements.
- The M2M application meta-model SHOULD allow to specify commands that can be sent by a server to a device.
- The M2M application meta-model SHOULD allow to specify events that can be sent by a device to a server.
Device Management
- The M2M application meta-model MUST allow the description of the Device Management operations supported by a given system.
- The M2M application meta-model SHOULD allow to indicate the binary files the application is made of.
Application Lifecyle Management
- The M2M application meta-model SHOULD allow to specify which application container is managing an application
- The M2M application meta-model SHOULD allow to specify dependencies towards capabilities of the underlying device the application is to be deployed on.
- The M2M application meta-model SHOULD allow to validate a software package
Non-functional requirements
- It MUST be possible to edit an M2M model instance using a standard text editor.
- It SHOULD be possible to provide graphical visualization of an M2M model instance.
- It SHOULD be possible to split an M2M model instance into several pieces to ease maintenance and reuse.
