This presentation was made at MoMo Athens Cross-Screen Development event by Webinos on October 22, 2012

1. Mobile Monday Athens
Introduction to webinos
Getting Gadgets Talking
Open Source Web
Framework for Secure
Cross Device Applications

2. What is webinos
An open
source web
application
platform for
multiple
devices
Supported by a strong consortium

3. 3

4. Big Problems
Fragmentation/ Interoperability
Silos : app-stores
Cross Device: especially offline
Experience Roaming
Ownership of data

19. GETTING DEVICES WORKING
TOGETHER

20. Cross Device Requirements
What do we need?
 Interoperable web application packaging
 Device and User Identity + Addressability
 Cross device synchronisation
 Peer2Peer Connectivity
 Device and Service Discovery
 Distributed Policy Framework
 Remoting mechanisms
 Defined Interoperable APIs
 A data sharing model
20

21. Technologies
 Node.js: primary implementation is based on cross platform node.js
 PKI model: webinos uses a distributed certificate model to identify
users and devices, online or offline - Identity
 TLS: mutually authenticated connections give the overlay network
security
 XACML: is used as the basis of the policy framework
 WIDL/Feature URI: forms the basis of the service description and
discovery model
 JSON-RPC: is used to allow JavaScript to be called remotely
 W3C Widgets: generic secure packaging mechanism
 JavaScript APIs: defined, interoperable device and service access
 Connection Manager: Peer to Peer and optimised networking

26. Final Takeaways
 Convergence is a trend
– Which platform for developing for apps across devices
– How will they work together?
 Web is the “universal” platform
 Webinos is OPEN
– Not led by any SINGLE company
 Webinos is compatible (needed?) by many other Oss
(including web based OS)
 Webinos is a consumer centric view of privacy and
security
 Free to join…
 Free to use...
