2 What Is the Tizen TM software platform? What Is The Tizen TM Software Platform? Tizen is an open source project housed within The Linux* Foundation with the goal of building an innovative web-based platform built upon industry standards. From enthusiastic developers to multinational companies, Tizen s mixture of contributors at every level ensures dynamic growth, diverse viewpoints which stimulate innovation, long-term stability and a commitment to performance. Tizen aims to introduce a robust unified experience across multiple devices smartphone, tablet, Smart TV, PC and in-vehicle infotainment with a focus on mobile platforms. Tizen is not based on proprietary technologies, but on industry-standard open specifications such as HTML5 and JavaScript*. Whereas other platforms may relegate such technologies to Web-specific secondclass citizens, Tizen embraces the benefits of widely adopted cross-platform web technologies and enables the creation of devices running open and innovative content and services.

3 Tizen platform development is led by two bodies, the Tizen Association and the Technical Steering Group. The Tizen Association is a mobile operator-led, industry consortium chartered with actively developing the ecosystem around Tizen, which includes market presence, gathering of requirements, identification and facilitation of service models, and overall industry marketing and education. The Tizen Technical Steering Group is focused on architecture and implementation, along with the formation of working groups to support device verticals. Many members of the Tizen Community are active contributors to the W3C and other web standards bodies. Tizen aims to introduce a robust unified experience across multiple devices with a focus on mobile platforms LINUX FOUNDATION The Linux Foundation is a non-profit consortium dedicated to fostering the growth of Linux. Founded in 2000, the Linux Foundation sponsors the work of Linux creator Linus Torvalds and is supported by leading technology companies and developers from around the world. org/about/ WC3 and HTML5 The World Wide Web Consortium (W3C) is an international community where Member organizations, a full-time staff, and the public work together to develop Web standards. On December of 2012, the W3C published the complete definition of HTML5 and Canvas 2D specifications. Though not yet W3C standards, these specifications are now feature complete, meaning businesses and developers have a stable target for implementation and planning

4 The Open Tizen Platform Foundations for Success: The Tizen Open Platform Tizen breathes fresh air into the mobile market by enabling innovation from both industry leaders and individual enthusiasts. Operators and their subscribers can benefit from end to end customization options and capabilities, not restricted by competing platform business interests or inflexible service licensing terms. This ability to customize elements such as the user interface, the selection of pre-installed services and the application storefront is a powerful part of the Tizen platform, and enables the value proposition of Tizen solutions to be uniquely tailored to meet operator and end user preferences. Tizen s open source heritage replaces a complicated landscape of vertically integrated platform solutions with an open and transparent consortium. The Tizen platform is based on the open source Linux operating system, which in the last few years has become the operating system of choice for the majority of smartphones. While Tizen currently emphasizes support for smartphones, its roadmap includes support for a wide range of devices such as tablets, PC s and in-vehicle infotainment systems. Tizen s open platform lends itself to a virtuous cycle of industry innovation. The standards-based web platform will encourage cutting-edge app developers to leverage their existing skills to easily port their content to Tizen. The combination of developer content and the freedom to pursue any mix of services best suited for local demands will motivate operators to offer Tizen devices and custom services on their networks. This in turn will encourage leading mobile original equipment manufacturers (OEMs) to invest in developing cutting-edge Tizen devices. The Tizen cycle of innovation is built upon an open source operating system, a standards-based web application framework, and an open services model a combination which has the potential to yield an industry dynamic where more parties benefit from the growth in the mobile industry. Leverage the Power of Web-Based Development Tizen web applications do not require complicated build processes or specialized build tools. Applications are executed in an environment that is familiar to anyone who has worked on web development. Due to the use of existing Web technologies, developers have access to thousands of already available 4

5 libraries. In many cases, these libraries will work even better on Tizen than in other web browsers since at the time of writing, Tizen s Web rendering engine boasts one of the highest HTML5 compliance scores of any released browser on both Ringmark and html5test.com. While it is easy for developers to create a Tizen Web application, most real-world applications are quite complex. To help manage the growth from a basic test application to a release-ready product, Tizen comes with robust development tools. The default Tizen development environment is based on the widely used Eclipse* platform, and developers can easily configure other environments if they choose. Tizen development extends beyond the standard Web applications. It includes extensions to the basic HTML5 platform which enable web applications to intercommunicate and access device functionality, such as Address Book and Call History. Developers also have the option of writing hybrid or native applications for even more flexibility. Also, cross-platform development through Apache Cordova a framework that allows developers to build cross-platform hybrid applications using HTML5 code allows Tizen to share a common codebase with other mobile platforms. Tizen web applications do not require complicated build processes or specialized build tools The Tizen IDE The Tizen SDK comes equipped with an Integrated Development Environment (IDE) based on Eclipse*, a device emulator based on QEMU, a visual UI builder, debugging and profiling tools, sample code and documentation, among many other features. 5

The main development language is HTML5. In fact, most developers either already have or plan to acquire the HTML5 skills needed to develop on Tizen 1. The toolset is free and based on existing and stable technologies. The Tizen development kit download includes sample applications that run out of the box. The Tizen development kit comes with a GUI builder tool which allows developers to quickly lay out their applications using simple drag-and-drop. The generated layout files are in standard HTML, which can be easily tracked through version control and merged automatically. Benefit from Code Reuse Another benefit of Tizen s focus on standard technologies is that it enables extensive code reuse. Moreover, code initially targeting Tizen can be easily ported to the Web or Web Views within other platforms. Tizen follows the recommendations of the W3C's governing Web standards when adding these capabilities. As other platforms catch up, developers will already have code written and tested that leverages these technologies. 6

7 By embracing proven technologies, Tizen provides a unique opportunity for developers to leverage their existing experience. Because the technologies are familiar and the APIs unchanged, any developer with a Web-based application need only add a bit of simple plumbing and repackage their code in order to have a Tizen version of that same application. The language, paradigms, tricks, and assets are all the same. In many cases, the necessary changes will be no more complicated than configuration and packaging, leaving core code essentially untouched. Bring Ideas to Life: Enabling Developers Tizen web application packages can include native code. This hybrid model enables web applications to take advantage of a developer s prior investments in native code, resulting in a shorter time-to-market and lower development costs. Another benefit of this model is that applications that started out as Web apps can contain wrapped versions of what would normally be server-side logic. This enables the Tizen version to mirror the Web version very closely, often requiring changes only to how this extended functionality is accessed rather than necessitating rewrites. GUI Builder The Tizen Web UI Builder is a graphical user interface builder tool that simplifies the creation of Tizen Web UIs by allowing developers to arrange widgets using a drag-and-drop What You See Is What You Get (WYSIWYG) editor. Tizen provides a compelling and robust inter-process communication model. Applications from the same developer can call each other directly for extended functionality. They can also make generic system requests, giving developers the freedom to decide how tightly integrated their applications 90% HTML5 USE BY MOBILE DEVELOPERS HTML5 use by mobile developers 80% 70% 60% 50% 40% 30% 20% 6.60% 30.70% 43.10% No plans Plan to use in 12 months or longer Plan to use in 6 months Currently using 10% 0% Yes 19.60% No 7

8 Tizen device adaptability offers exciting possibilities for crossdevice synergy should be. Developers can create application suites that users can install à la carte, with each application extending the functionality of the others while keeping the user within related sets of tools or functionality. This API also permits querying for the presence of other applications, allowing the collection of extensive analytics data that is usually difficult or impossible to gather. In addition to standard debugging and profiling functionality, the Tizen emulator supports simulations of a wide range of real-world events to which applications might want to react. Far beyond the basic location settings and loss of data connection, the emulator allows mocking of the proximity sensor, the light sensor, near-field communication functionality, headset insertion, and more. Support Multiple Device Types The Tizen OS is designed to be adaptable to multiple device types from simple, low end printers to sophisticated automotive systems. Today, there are releases tailored to smartphones and automotive or IVI (in vehicle infotainment), and more types of devices will be supported over time. Moreover, as the number of device types increases, Tizen will continue to adhere to and influence W3C web APIs to ensure app compatibility. A number of Tizen Association members are participating in W3C efforts to create an Automotive Working RESPONSIVE WEB DESIGN Thanks to responsive web design, Tizen HTML5 applications can easily adapt the user interface layout to match different screen sizes without the need for device-specific code. 8

9 Group which will work on a standard for automotive-specific web APIs. Tizen device adaptability offers exciting possibilities for crossdevice synergy. For example, many consumers use Bluetooth to output audio from a phone or audio player through a car s speaker system. Tizen s cross-device focus and extensive APIs go far beyond simple pairing. An application might offer different options when devices with different capabilities are paired. For example, a Tizen phone could display driving information gained from a vehicle that is also running Tizen. Tizen's user interface expectations are much more freeform than other platforms. Most platforms expect certain configurations of physical buttons, and deviating from these configurations can be difficult. Tizen does not place strict restrictions on the position, size, or even existence of physical buttons. Rather, Tizen features a touch screen and emphasizes that presenting a consistent experience across devices is an important part of creating usable software. OEMs have access to a Compliance Definition Document and a Compatibility Test Suite to ensure that their hardware complies with the full Tizen specifications. The behaviors specified in these documents ensure that Tizen applications will run on all devices across the Tizen ecosystem. Traditionally, diverse device screen sizes have presented challenges for software designers because each screen can require complete UI restructuring. Because Tizen relies on the same HTML technologies that pioneered the principles of responsive web design answering the question of how to resize content for multiple aspect ratios and screen sizes OEMs can rely upon the platform to render content appropriately without a need for device-specific UI code. This reduces the risk when supporting new form factors that existing applications might render in unpredictable ways, which enables developers to focus on what is on the screen, rather than where and how big it is. Built-in Security Tizen also offers advanced security controls such as Mandatory Access Control via SMACK, or Simple Mandatory Access Control Kernel. With SMACK, Tizen ensures that malicious applications are unable to bypass the proper permission levels and security checks, giving developers and customers further confidence that they are in control of their data. Application access protocols Tizen s hardware user interface expectations are much more freeform than other platforms 9

10 operators and manufacturers can customize the Tizen storefront are based on well-understood and time-tested security models. All applications run in a sandbox and nothing but critical system processes run with root permissions, minimizing the attack surface for malware. Even though author and distributor signatures are mandatory to ensure code integrity, unsigned applications can be loaded onto registered test devices during the development cycle. Signing is handled as part of the application submission stage, after the developer has packaged the application. This enables the platform to maintain all of the security benefits of a signed application security model while simplifying the developer experience. Application Store The Tizen application ecosystem supports developers by providing multi-operator distribution throughout the world, which in turn promotes the porting of content. Once a Tizen application is submitted to the Tizen Store, it undergoes validation to ensure that it meets the platform s compatibility requirements. Another key strength of the Tizen distribution platform is that operators and OEMs can customize the Tizen storefront to maintain their brand and highlight their services. Developers can publish once and gain the benefits of a variety of marketplaces worldwide. Strength in Community OEMs, operators, developers, and consumers can also connect directly through the Tizen developer community and participate in shaping the future of the platform through the open source Tizen project. Where there are no existing Web standards, the Tizen community will look to add APIs and to work with the W3C to get these APIs added to the relevant web technology specifications. For example, Tizen Association members are actively involved in the W3C s Device APIs Working Group and the System Applications Working Group. This involvement ensures that the platform not only complies with the specifications, but also is designed with the same goals and implemented intuitively. 10

11 Conclusion Tizen brings together OEMs, operators and developers, enabling a community that can tailor the end-user experience and shape the future of the platform. This collaboration ultimately creates a new, more balanced industry dynamic that benefits all members of the Tizen ecosystem. Conclusion A new, more balanced industry dynamic By adopting existing standards whenever possible, Tizen allows developers to reuse their existing code and leverage their knowledge in HTML5 and other web development technologies. Tizen also includes extended APIs and a hybrid development model that provide developers with the flexibility needed to create rich user experiences. This balance, complemented by a powerful toolset that accelerates development and a secure infrastructure that protects valuable information, yields an open platform where developers can push the limits of innovation.
