This document outlines the Webinos API specifications presented at an Oxford meeting in July 2013. It discusses the goals of reusing existing W3C API specifications where possible and standardizing any new APIs within W3C. An overview is given of the Webinos and W3C APIs that have been reused, modified, or are being provided as input for standardization. Key features of Webinos include finding and accessing remote services using the Webinos Service Discovery API along with relevant Webinos or W3C access APIs. Twenty-four new Webinos APIs and eight reused W3C APIs are specified across areas such as sensors/actuators, media, data storage, communication, and security.

Goals
 Easy to use APIs for web developers that support
webinos use cases
 Don’t re-invent the wheel, re-use existing API
specifications, preferable from W3C, as much as
possible
 When needed modify existing API or specify new
APIs but align our with W3C style as much as
possible
 New APIs are subject for standardization within
W3C

5. 6
webinos key feature
is the ability to find
and use a service in
a remote device

6. 7
Webinos key feature!
1. The webinos Service
Discovery API is used to find
and bind to a service
2. A webinos or W3C API is
used to access the service

7. 8
Webinos Service
Discovery API
• High level API. All low level protocol details hided to
web developer.
• Discoverable service must reside on devices
registered in a webinos personal zone.
• The ”Service Type” to search for relates to the
Webinos or W3C API used to access the service.
Example:
• http://webinos.org/api/sensors/temperature
(Search for temperature sensors. The webinos sensor
API is used to access the sensor data)

{onFound:serviceFoundCB});
3. User selects media content service  Mobile
application binds to selected media content service.
4. Mobile application uses webinos MediaContent API to
access the remote media content service.
Precondition: User registers devices/services as members
of the Personal Zone, alt using MDNS to find services
dynamically
MediaContent API
2. Mobile application lists discovered media content services
for user selection.

Working with W3C
 webinos is active in the W3C System
Applications WG
– Runtime and Security model
– Raw Socket API
– webinos has valuable input to next phase
SysApps APIs, e.g. Media Storage, Secure
Elements
 W3C NFC WG
– Feeding back experiences from webinos NFC API
specification and implementation
