WEBINOS API SPECIFICATIONS-

OXFORD MEETING JULY 2013

Claes Nilsson, Sony Mobile

Presented by Christian Fuhrhop, Fraunhofer FOKUS

3

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

Webinos enables access to remote services 

6

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

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

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)

MediaContent API

ServiceDiscovery API

1. window.webinos.discovery.findServices( {api:' http://webinos.org/api/mediacontent '}, {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.

webinos TV Control API:Provides means to acquire a list of TV sources, channels and their streams.

webinos Media Content API:Access to multimedia contents (images, music, videos). Based on Tizen MediaContent API.

14

webinos APIs – Data Storage

W3C File API: Allows web applications to read files on a device.

W3C File API: Writer: Allows web applications to write to files.

W3C File API: Directories and System:Allows web applications to navigate file system hierarchies.

15

webinos APIs – Communication/Messaging

webinos Messaging APISending, receiving and searching SMS, MMS, E-mail and IM.

webinos App2App Messaging APIMessaging between webinos applications.

W3C PeerConnection API:Allows media to be sent and received over the network to another browser.

16

webinos APIs – Personal Information

webinos Contacts API:Provides access to a user unified address book. Based on old W3C DAP Contacts API and WAC Contacts API.

W3C Calendar API:Provides access to a user calendaring service.(old shelved W3C DAP version, to be replaced with W3C SysApps Calendar API when that is done.)

17

webinos APIs – User Interaction

webinos Web Notifications API:Display notifications outside the context of a web page. Based on the W3C Web Notifications API.

webinos Remote UI API:Create and access a UI on a remote device and manipulate DOM objects.

18

webinos APIs – Security

webinos Authentication APIProvides information to applications about the current authentication status of users.

webinos Secure Elements API:Access to application on a smart card or any other secure element.

19

webinos APIs – Misc

webinos Core interface: Defines the webinos namespace and provides information about the personal zone.

webinos AppLauncher API:Activation of webinos applications on the device.

webinos Widget API:W3C Widget API with webinos extensions.

Webinos Personal

Zone

20

webinos APIs – Misc

webinos Context API:Enables access to a user's context data.

webinos Payment API: Provides in-app payment.

webinos AppState Synchronization API:Enable and manage application synchronisation.

21

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
