AW: Topics for W3C workshop?

Dear all,

some thoughts from us. Currently we have various IoT platforms such as Xively, The Thing System, Carriots, Temboo etc. There is a lack of connecting all these platforms and their related services and applications. I feel that there is a need to define unified APIs and protocols on top of current standards. With the challenge to motivate a hub of IoT platforms and not building the next new IoT platform. We need overall approaches to connect all these platforms. If you are looking at http://iotlist.co/ you will find an enormous number new devices and applications for the smart home and connected home domain. These implies standards for service discovery, pairing and session mobility across all these devices. Furthermore, we have an Internet of applications in mainstream marketplaces. Why not thinking about an Internet of services for smart home and connected home. 

Currently you will find lightweight node.js applications which are running on servers, microcontrollers and single-board computers. This includes various prototype applications with proprietary implementations for exposing these hardware components to the web. So we need standardized APIs for enabling these kind of node.js applications and hardware. Additionally we find a moving trend in the SmartTV domain to Web technologies. This grounding should be used to enable Web technologies for smart home, connected home and wearable device.


Best regards / Mit Besten Grüßen

Betreff: Topics for W3C workshop?

I would like to encourage some brainstorming about potential areas for W3C to standardize and how we could explore these in the workshop we're planning for June.

Protocols and APIs:

There are many communication technologies for the IoT and this reflects the varying requirements. For W3C HTTP and Web Sockets are core protocols, but we are also working on NFC, Bluetooth, network service discovery and access to raw IP sockets. Should W3C consider work on script APIs for other protocols?  What kinds of coordination are needed across standardization bodies?

Apps and Services:

W3C has so far concentrated on standards for HTML and related formats, e.g. for style sheets, scripts and style sheets.  There is an increasing interest in the use of JavaScript for implementing services, e.g. with node.js on home gateways, and even subsets of JavaScripts for use on microcontrollers.. Is it time for W3C to coordinate standards for APIs for use by scripts running on servers?

For a market of value added services, there will be a need for a means to declare what the service exposes, and what it depends upon.  Is there a need for work on interface definition languages for this?  Some requirements include the need for shared semantics (e.g. for physical units),  and integrity constraints that the platform can enforce for increased robustness. What additional requirements are there for markets of services, e.g. scalability, real-time services, payments, compositions of services, APIs for authoring tools, etc.

Security, trust and privacy:

What are the issues and associated requirements?  This includes: mutual authentication, provenance, access control and privacy policies.  What do we need to do to support retroactive security, e.g. support for monitoring and recovering from problems?

The role of semantics:

Shared semantics is key enabling an open market of services. The Web of Things can be positioned as the combination of tags, sensors and actuators with rich descriptions, e.g. of people, devices, places, and events to enable open markets of value added services, in other words, the merger of the Internet of things and the Web of data to create a Web of services. Open questions include who describes what and when, along with how to combine linked data and services

Please contribute your ideas to this discussion.
