Tizen ( / ˈ t aɪ z ɛ n / ) is a Linux -based mobile operating system backed by the Linux Foundation , developed and used primarily by Samsung Electronics .
47-543: The project was originally conceived as an HTML5 -based platform for mobile devices to succeed MeeGo . It was backed by other companies under the Tizen Association . Samsung merged its previous Linux-based OS effort, Bada , into Tizen and has since used it primarily on platforms such as wearable devices and smart TVs . Much of Tizen is open source software , although the software development kit contains proprietary components owned by Samsung, and portions of
94-430: A Candidate Recommendation. The criterion for advancement to W3C Recommendation is "two 100% complete and fully interoperable implementations". On 16 September 2014, W3C moved HTML5 to Proposed Recommendation. On 28 October 2014, HTML5 was released as a W3C Recommendation, bringing the specification process to completion. On 1 November 2016, HTML 5.1 was released as a W3C Recommendation. On 14 December 2017, HTML 5.2
141-543: A Living Standard for HTML, continuously maintaining the specification rather than freezing it in a state with known problems, and adding new features as needed to evolve the platform. Since then, the WHATWG has been working on this specification (amongst others), and the W3C has been copying fixes made by the WHATWG into their fork of the document (which also has other changes). The two entities signed an agreement to work together on
188-758: A form of DRM, was "in scope" and will potentially be included in the HTML 5.1 standard. WHATWG 's "HTML Living Standard" continued to be developed without DRM-enabled proposals. Manu Sporny, a member of the W3C , said that EME would not solve the problem it was supposed to address. Opponents point out that EME itself is just an architecture for a DRM plug-in mechanism. The initial enablers for DRM in HTML5 were Google and Microsoft. Supporters also include Adobe. On 14 May 2014, Mozilla announced plans to support EME in Firefox ,
235-454: A position paper at a World Wide Web Consortium workshop in June 2004, focusing on developing technologies that are backward-compatible with existing browsers, including an initial draft specification of Web Forms 2.0. The workshop concluded with a vote—8 for, 14 against—for continuing work on HTML. Immediately after the workshop, WHATWG was formed to start work based upon that position paper, and
282-613: A second draft, Web Applications 1.0, was also announced. The two specifications were later merged to form HTML5. The HTML5 specification was adopted as the starting point of the work of the new HTML working group of the W3C in 2007. WHATWG's Ian Hickson ( Google ) and David Hyatt ( Apple ) produced W3C's first public working draft of the specification on 22 January 2008. Many web browsers released after 2009 support HTML5, including Google Chrome 3.0, Safari 3.1, Firefox 3.5 , Opera 10.5, Internet Explorer 9 and later. While some features of HTML5 are often compared to Adobe Flash ,
329-480: A single version of HTML on 28 May 2019. In addition to the contradiction in the < cite > element mentioned above, other differences between the two standards include at least the following, as of September 2018 : §9 Communication §10 Web workers §11 Web storage <address> is in section Grouping content . <address> is in section Sections . § 4.3.11.3 Exposing outlines to users The following table provides data from
376-479: A topic of mainstream media attention around April 2010 after Apple Inc. 's then-CEO Steve Jobs issued a public letter titled "Thoughts on Flash" in which he concluded that "Flash is no longer necessary to watch video or consume any kind of web content" and that "new open standards created in the mobile era, such as HTML5, will win". This sparked a debate in web development circles suggesting that, while HTML5 provides enhanced functionality, developers must consider
423-432: A wide variety of current Samsung products running Tizen, such as Smart TVs and mobile phones. After the article was published, Samsung, whom Neiderman tried to contact months before, reached out to him to resolve the issues. In December 2016, Samsung created TizenRT, a fork of NuttX , a real-time operating system (RTOS), for smart home appliances and IoT devices. HTML5 HTML5 ( Hypertext Markup Language 5 )
470-723: Is a markup language used for structuring and presenting hypertext documents on the World Wide Web . It was the fifth and final major HTML version that is now a retired World Wide Web Consortium (W3C) recommendation. The current specification is known as the HTML Living Standard . It is maintained by the Web Hypertext Application Technology Working Group (WHATWG), a consortium of the major browser vendors ( Apple , Google , Mozilla , and Microsoft ). HTML5
517-623: Is also a candidate for cross-platform mobile applications because it includes features designed with low-powered devices in mind. Many new syntactic features are included. To natively include and handle multimedia and graphical content, the new <video> , <audio> and <canvas> elements were added; expandable sections are natively implemented through <summary>...</summary> and <details>...</details> rather than depending on CSS or JavaScript; and support for scalable vector graphics (SVG) content and MathML for mathematical formulas

#1732782330086564-631: Is also possible using JavaScript and HTML 4 , and within SVG elements through SMIL , although browser support of the latter remains uneven as of 2011 . XML documents must be served with an XML Internet media type (often called " MIME type") such as application/xhtml+xml or application/xml , and must conform to strict, well-formed syntax of XML. XHTML5 is simply XML-serialized HTML5 data (that is, HTML5 constrained to XHTML's strict requirements, e.g., not having any unclosed tags), sent with one of XML media types. HTML that has been written to conform to both
611-456: Is intended to subsume not only HTML 4 but also XHTML1 and even the DOM Level 2 HTML itself. HTML5 includes detailed processing models to encourage more interoperable implementations; it extends, improves, and rationalizes the markup available for documents and introduces markup and application programming interfaces (APIs) for complex web applications . For the same reasons, HTML5
658-476: The Fortune 500 U.S. companies implemented HTML5 on their corporate websites. Since 2014, HTML5 is at least partially supported by most popular layout engines. The following is a cursory list of differences and some specific examples. W3C Working Group publishes "HTML5 differences from HTML 4", which provides a complete outline of additions, removals and changes between HTML5 and HTML4. On 18 January 2011,
705-562: The OBD-II port underneath the steering wheel. On November 16, 2016, Samsung said they would be collaborating with Microsoft to bring .NET Core support to Tizen. According to Strategy Analytics research, approximately 21% of the smart TVs sold in 2018 run on the Tizen platform making it the most popular smart TV platform. On May 19, 2021, during Google I/O , Google announced that Samsung had agreed to work on integrating features of Tizen with
752-403: The HTML and DOM standards to WHATWG on 28 May 2019, as it considered that having two standards is harmful. The HTML Living Standard is now authoritative. However, W3C will still participate in the development process of HTML. Before the ceding of authority, W3C and WHATWG had been characterized as both working together on the development of HTML5, and yet also at cross purposes ever since
799-403: The HTML and XHTML specifications and therefore produces the same DOM tree whether parsed as HTML or XML is known as polyglot markup . There is no DTD for XHTML5. HTML5 is designed so that old browsers can safely ignore new HTML5 constructs. In contrast to HTML 4.01, the HTML5 specification gives detailed rules for lexing and parsing , with the intent that compliant browsers will produce
846-407: The HTML5 specification work, focusing on a single definitive standard, which is considered a "snapshot" by WHATWG. The WHATWG organization continues its work with HTML5 as a "living standard". The concept of a living standard is that it is never complete and is always being updated and improved. New features can be added but functionality will not be removed. In December 2012, W3C designated HTML5 as
893-659: The HTML5 specification, and HTML5 also better defines the processing for any invalid documents. The Web Hypertext Application Technology Working Group (WHATWG) began work on the new standard in 2004. At that time, HTML 4.01 had not been updated since 2000, and the World Wide Web Consortium (W3C) was focusing future developments on XHTML 2.0 . In 2009, the W3C allowed the XHTML 2.0 Working Group's charter to expire and decided not to renew it. The Mozilla Foundation and Opera Software presented
940-493: The July 2012 split. The W3C "HTML5" standard was snapshot-based (HTML5, HTML 5.1, etc.) and static, while the WHATWG "HTML living standard" is continually updated. The relationship had been described as "fragile", even a "rift", and characterized by "squabbling". In at least one case, namely the permissible content of the < cite > element, the two specifications directly contradicted each other (as of July 2018), with
987-606: The Mozilla Development Network on compatibility with major browsers, as of September 2018 , of HTML elements unique to one of the standards: The W3C proposed a greater reliance on modularity as a key part of the plan to make faster progress, meaning identifying specific features, either proposed or already existing in the spec, and advancing them as separate specifications. Some technologies that were originally defined in HTML5 itself are now defined in separate specifications: Some features that were removed from

#17327823300861034-599: The OS are licensed under the Flora License , a derivative of the Apache License 2.0 that grants a patent license only to "Tizen-certified platforms". In May 2021, Google announced that Samsung would partner with the company on integrating Tizen features into Google's Android -derived Wear OS and committed to using it on future wearables, leaving Tizen to be mainly developed for Samsung Smart TVs. The project
1081-448: The W3C definition allowing a broader range of uses than the WHATWG definition. The "Introduction" section in the WHATWG spec (edited by Ian "Hixie" Hickson ) is critical of W3C, e.g. " Note: Although we have asked them to stop doing so, the W3C also republishes some parts of this specification as separate documents." In its "History" subsection it portrays W3C as resistant to Hickson's and WHATWG's original HTML5 plans, then jumping on
1128-580: The W3C introduced a logo to represent the use of or interest in HTML5. Unlike other badges previously issued by the W3C, it does not imply validity or conformance to a certain standard. As of 1 April 2011, this logo is official. When initially presenting it to the public, the W3C announced the HTML5 logo as a "general-purpose visual identity for a broad set of open web technologies, including HTML5, CSS , SVG, WOFF , and others". Some web standard advocates, including The Web Standards Project , criticized that definition of "HTML5" as an umbrella term, pointing out
1175-545: The above technologies are included in the W3C HTML5 specification, though they are in the WHATWG HTML specification. Some related technologies, which are not part of either the W3C HTML5 or the WHATWG HTML specification, are as follows. The W3C publishes specifications for these separately: HTML5 cannot provide animation within web pages. Additional JavaScript or CSS3 is necessary for animating HTML elements. Animation
1222-413: The bandwagon belatedly (though Hickson was in control of the W3C HTML5 spec, too). Regardless, it indicates a major philosophical divide between the organizations: For a number of years, both groups then worked together. In 2011, however, the groups came to the conclusion that they had different goals: the W3C wanted to publish a "finished" version of "HTML5", while the WHATWG wanted to continue working on
1269-450: The blurring of terminology and the potential for miscommunication. Three days later, the W3C responded to community feedback and changed the logo's definition, dropping the enumeration of related technologies. The W3C then said the logo "represents HTML5, the cornerstone for modern Web applications". Industry players including the BBC , Google, Microsoft , Apple Inc. have been lobbying for
1316-464: The end of 2020. Adobe itself officially discontinued Flash on 31 December 2020 and all Flash content was blocked from running in Flash Player as of 12 January 2021. On 14 February 2011, the W3C extended the charter of its HTML Working Group with clear milestones for HTML5. In May 2011, the working group advanced HTML5 to "Last Call", an invitation to communities inside and outside W3C to confirm
1363-583: The inclusion of Encrypted Media Extensions (EME), a form of digital rights management (DRM), into the HTML5 standard. As of the end of 2012 and the beginning of 2013, 27 organizations including the Free Software Foundation have started a campaign against including digital rights management in the HTML5 standard. However, in late September 2013, the W3C HTML Working Group decided that Encrypted Media Extensions,
1410-488: The last major browser to avoid DRM. Calling it "a difficult and uncomfortable step", Andreas Gal of Mozilla explained that future versions of Firefox would remain open source but ship with a sandbox designed to run a content decryption module developed by Adobe, later it was replaced with Widevine module from Google which is much more widely adopted by content providers. While promising to "work on alternative solutions", Mozilla's Executive Chair Mitchell Baker stated that
1457-484: The more capable Cascading Style Sheets . There is also a renewed emphasis on the importance of client-side JavaScript used to create dynamic web pages . The HTML5 syntax is no longer based on SGML despite the similarity of its markup. It has, however, been designed to be backward-compatible with common parsing of older versions of HTML. It comes with a new introductory line that looks like an SGML document type declaration , <!DOCTYPE html> , which triggers

1504-491: The next version of Wear OS , and that it had committed to using Wear OS for its future wearable products. Samsung will continue to use Tizen for its smart TVs. On December 31, 2021, the Tizen app store permanently closed. The last smartphone based on the Tizen operating system is the Samsung Z4 which was released in 2017. The company switched to Google's Wear OS 3 platform on its Galaxy Watch 4 smartwatches. Samsung Z
1551-411: The original HTML5 specification have been standardized separately as modules, such as Microdata and Canvas . Technical specifications introduced as HTML5 extensions such as Polyglot markup have also been standardized as modules. Some W3C specifications that were originally separate specifications have been adapted as HTML5 extensions or features, such as SVG . Some features that might have slowed down
1598-542: The project, Linux Foundation initiated the Tizen project as a successor to MeeGo, another Linux-based mobile operating system, with its main backer Intel joining Samsung Electronics , as well as Access Co. , NEC Casio , NTT DoCoMo , Panasonic Mobile , SK Telecom , Telefónica , and Vodafone as commercial partners. Tizen would be designed to use HTML5 apps, and target mobile and embedded platforms such as netbooks , smartphones, tablets, smart TVs , and in-car entertainment systems. U.S. carrier Sprint Corporation (which
1645-480: The same results when parsing incorrect syntax. Although HTML5 now defines a consistent behavior for " tag soup " documents, those documents do not conform to the HTML5 standard. According to a report released on 30 September 2011, 34 of the world's top 100 Web sites were using HTML5 – the adoption led by search engines and social networks . Another report released in August 2013 has shown that 153 of
1692-742: The standardization of HTML5 were or will be standardized as upcoming specifications, instead. HTML5 introduces elements and attributes that reflect typical usage on modern websites. Some of them are semantic replacements for common uses of generic block ( <div> ) and inline ( <span> ) elements, for example <nav> (website navigation block), <footer> (usually referring to bottom of web page or to last lines of HTML code), or <audio> and <video> instead of <object> . Some deprecated elements from HTML 4.01 have been dropped, including purely presentational elements such as <font> and <center> , whose effects have long been superseded by
1739-438: The standards-compliant rendering mode . Since 5 January 2009, HTML5 also includes Web Forms 2.0 , a previously separate WHATWG specification. In addition to specifying markup, HTML5 specifies scripting application programming interfaces (APIs) that can be used with JavaScript . Existing Document Object Model (DOM) interfaces are extended and de facto features documented. There are also new APIs, such as: Not all of
1786-439: The technical soundness of the specification. The W3C developed a comprehensive test suite to achieve broad interoperability for the full specification by 2014, which was the target date for recommendation. In January 2011, the WHATWG renamed its "HTML5" specification HTML Living Standard . The W3C nevertheless continued its project to release HTML5. In July 2012, WHATWG and W3C decided on a degree of separation. W3C will continue
1833-436: The two technologies are very different. Both include features for playing audio and video within web pages, and for using Scalable Vector Graphics . However, HTML5 on its own cannot be used for animation or interactivity – it must be supplemented with CSS3 or JavaScript . There are many Flash capabilities that have no direct counterpart in HTML5 (see Comparison of HTML5 and Flash ). HTML5's interactive capabilities became
1880-402: The varying browser support of the different parts of the standard as well as other functionality differences between HTML5 and Flash. In early November 2011, Adobe announced that it would discontinue the development of Flash for mobile devices and reorient its efforts in developing tools using HTML5. On 25 July 2017, Adobe announced that both the distribution and support of Flash would cease by

In January 2013, Samsung announced its intent to release multiple Tizen-based phones that year. In February 2013, Samsung merged its Bada operating system into Tizen. In October 2013, the first Tizen tablet

To enrich the semantic content of documents, new page structure elements such as <main> , <section> , <article> , <header> , <footer> , <aside> , <nav> , and <figure> are added. New attributes were introduced, some elements and attributes were removed, and others such as <a> , <cite> , and <menu> were changed, redefined, or standardized. The APIs and Document Object Model (DOM) are now fundamental parts of

Its goals were to improve the language with support for the latest multimedia and other new features; to keep the language both easily readable by humans and consistently understood by computers and devices such as web browsers , parsers , etc., without XHTML's rigidity; and to remain backward-compatible with older software. HTML5

However, in the same month, Intel turned Moblin over to the Linux Foundation for future development. Eventually, the operating system was merged with Nokia Maemo , a Debian based Linux distro, into MeeGo which was mainly developed by Nokia, Intel and Linux Foundation. In 2011, after Nokia abandoned
2162-407: Was released as a W3C Recommendation. The W3C retired HTML5 on 27 March 2018. Additionally, the retirement included HTML 4.0, HTML 4.01, XHTML 1.0, and XHTML 1.1. HTML 5.1, HTML 5.2 and HTML 5.3 were all retired on 28 January 2021, in favour of the HTML living standard. The combined timelines for the W3C recommendations of HTML5, HTML 5.1, HTML 5.2 and HTML 5.3: The W3C ceded authority over

In 2014, Samsung released the Gear 2 smartwatch that used a Tizen-based operating system as opposed to Android . On May 14, 2014, it was announced that Tizen would ship with Qt. This project was abandoned in January 2017. On February 21, 2016, Samsung announced the Samsung Connect Auto, a connected car solution offering diagnostic, Wi-Fi , and other car-connected services. The device plugs directly into
