● WebRuntime scores 492/500 @ html5test.com !
● System API are exposed
● Cross-platform :
Javascript Frameworks
● Cordova : union not intersection of possibilities
● Developer focus on adaptation not porting apps
● Alt Runtimes : crosswalk (android,tizen,w), Hydra, Qt?
●

Developpement Model
● Continuous Integration :
Requested Features / Report Bugs (jira)
● Build and test packages locally on selected profile (gbs)
●
▪ Integration of packages (RPM/.spec) into tizen git tree
▪ changes / patches pushed and reviewed (gerrit)
●
Maintainers and RE :
▪ Rebuild + publish .rpm in repos (obs)
▪ image released
●
