Subject: Web Services For Devices...

This working group needs to leverage existing work that is being conducted within OASIS and other standards initiatives, bringing them all together and applying them to devices. There are positive movements around event driven communications in heterogeneous environments, web services orchestration, composite applications and security that can all be built upon. We need to refine and understand the implications of these "enterprise" services application to the emerging (often resource limited) device network. Over time devices will become more powerful, but we need to forge a path between the here and now, and distant future.

The use of networked devices is growing at a lightning pace, driven by the need for OEM's, service providers and customers to add functionality, differentiate products and take cost out of post sales customer support functions. There is also an emergence of several classes of devices that can all benefit from the output of this working group. This market can be portrayed by the following matrix;


- Display centric devices: These are devices that rely on a display Eg. PDA's, HDTV
- Headless Devices: These are devices without a display. Eg. Switches and routers
- Fixed Position Devices: These are devices that do Eg. MRI machine
- Mobile Devices: These are devices that change location Eg. Delivery truck, pallets, mobile phones

The problem today is that the majority of the software for devices is proprietary. This results in tightly integrated systems that do not interoperate. To applications developers, the result is a heterogeneous and fragmented market. It has also forced the use of sub optimal components like embedded web servers which do not work well for device centric use scenarios (eg. provisioning, ordering etc.) that will drive real economic value for OEMs, service providers and customers.

Through this working group it is possible to define a set of standards that can be applied across all device classes that will allow for services to be exposed in a standard way and for 'any to any' and secure communications to take place in a loosely coupled world. This will benefit all industry participants, OEM's, networking companies, service providers and embedded systems software companies. OEM's will be able to add value added services, with built in greater customer care for end users. Networking companies hardware will act as natural device hubs. Service providers will be able to leverage 3rd party services, and add new service offerings. Embedded systems software vendors will be able to create out of the box solutions that offer total customizability and manageability. And finally, end-customers will greatly benefit from more flexible and customizable solutions.

Let me know what you think and what other standards initiatives we should be leveraging here.
