Tizen: Overview
7 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
Tizen : from where ?
● Mobile GNU/Linux distributions supported by HW vendors
● Mobile Distro : Tizen =((Moblin + Maemo) = Meego ) && ( SLP << Limo++)
9 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
Tizen : To where ?
● Maintained Releases● 2012 Tizen 1 : Web API (jqm)● 2013 Tizen 2 : +Native APIs (mobile only)
● Project switched to Open Developement● Public git, reviewing, discussion● Inclusive platform(Qt5)
● Upcoming :● Tizen 3 : multiusers, Wayland, realign upstream ...
10 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
Tizen : Why ?
● Hardware support from hardware vendors
● One base several verticals
● Security (AC, Cert, fs, SMACK ...)
● Connectivity & System
● App Framework (Web...)
● UI/UX Effecient (EFL)
● Aligned to upstream projects or standards : - linux kernel mainline, glibc, X11/Wayland
12 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
● Several Profiles (verticals)● Supported Ones :
▫ mobile (ARM/ia32) : RD210 (2.0), RDPQ , ZTE geek
▫ IVI (run on ia32 platform)
▪ Others :▫ Community : tablet, OpenHardware, yours?
▫ Unreleased : track news (Hint @TizenExperts MWC)
● One single Base : generic (run on PC)
● Download : http://download.tizen.org/
Tizen : When ?
Applications Developement
14 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
Why HTML5 ?
● “Chrome Javascript Is the New C Runtime” (/.)
● 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?
15 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
How to create Tizen applications ?
● Tizen SDK● IDE: eclipse
▪ command-line tools : debug, packaging, sign
● API :● Javascript / HTML5 apps
▪ API : W3C + Tizen (System)
● Native apps in C++ (Tizen::*) or Creating hybrid apps● Others : unsure build/hack your own platform ?
● Publish : on tizen store (mobile)
16 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
Platform Developement
18 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
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
● http://download.tizen.org/ ( snapshots | d | w | live )
19 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
Who ? Gouvernance
● Roles :▪ Developers : create change
▪ Reviewers : validate and merge it
▪ Maintainers : submit it to rebuild package
▪ Release Engineers or bots : release it
▪ Architects (per profile) + QA ...
▪ TSG : Tizen Steering Group is grouping architects
● Watch tizen-gouvernance-linuxcon-eu-2013 video
● Be Agile, good behaviour is success key

When to Contribute ? Now
● Create an account on TINF https://www.tizen.org/user/register
● Use tracker http://bugs.tizen.org
● Get source● Git / ssh / gerrit :
upload your ssh key ( ssh key-gen) https://review.tizen.org/gerrit/#/
● Gbs install and configure it● Start rebuild, patch and submit it
21 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
How to create tizen derivates ?
● Base on existing profile ● Build your packages using gbs● Use mic to install packages on an image to be booted
● Create your own profile (shared or private)● Adapt to unsupported hardware● Build your own image (obs) and release using mic
● Conform flora licence = benefit of tizen ecosystem
22 FOSDEM'14 Contributing to the Tizen Project <[email protected]>
Who to cooperate with ?
● UI/UX :● wayland (for IVI) or Xorg (on mobile ATM)● EFL / Qt (not supported ATM) but hosted...
● Web Runtime : ● WebKit / blink / crosswalk etc : gnu/linux + android ● JavaScript frameworks (grung, undersore, request)
● System : linux kernel, systemd, connman, ofono …
● Brotherhood : mer, bohdi, fedora, openSUSE ...

IMHO
● Please opensource your applications
● It's not mandatory but you will :● Get benefits of community● You can still sell them on store● Ease ports between platforms
● Share code or Design will help
● Joined efforts between communities
