HTML+5

= HTML 5 = toc Html 5 is the fifth major revision of Html started in 2004 and initially written by Ian Hickman. HTML 5 is intended to promote interoperability between all web technologies and replaces HTML 4, DOM2HTML, and XHTML1. Since that time HTML 5 has become a living standard that while in the working state continues to be adopted. Unlike past endeavors to produce a web standard WC3’s defined parameters of HTML5 already has wide adoption between all Major web browsers. In the early stages of development Fire Fox, Chrome, and Opera formed a competing working group to the WC3 that was later collapsed in to WC3. HTML5 is an attempt to increase the usability of HTML to promote standardized web development and the semantic web. HTML 5 hopes to eliminate the need for plugins by natively supporting a rich web experience including, video, audio, and the canvas tags as alternatives to Flash.

The major goals For HTML 5 as stated by the WC3 working group are :


 * 1) Defines a single language called HTML5 which can be written in HTML syntax and in XML syntax.
 * 2) Defines detailed processing models to foster interoperable implementations.
 * 3) Improves markup for documents.
 * 4) Introduces markup and APIs for emerging idioms, such as Web applications.

HTML 5 is really a platform for all other major web technologies such as: JavaScript, AJAX, and CSS 3. What people know of HTML 5 is really the convergence of these technologies to create rich web environments. Even though HTML 5 is not slated for completion until 2022 the language is backwards compatible and has seen adoption above HTML 4 already. The future of HTML 5 is more secure the previous iterations with wide adoption by all major web browsers even Internet Explorer 9. From a design perspective HTML 5 potentially will sing the death note of frames and flash on the internet. HTML5 takes a holistic approach to creating a web standard for the future that can support robust web development natively.

**Major New Elements Introduced in HTML 5** HTML 5 offers many benefits but one of the biggest is that it the need for plugins, most notably Flash, for multimedia and games.

Audio/Video Element code code These two elements eliminate the Flash plugin and is intended to become the standard for presenting multimedia on the web.

Canvas Element code code

Renders games, graphs, and visual images on the fly without the use of plugins. .The element is essentially a “canvas” to use other web technologies to, such as javascript, to create dynamically rendered graphics. This element opens HTML 5 as a base for app development.

While these two elements are have yet to be adopted as standards Adobe recently abandoned Flash as a mobile platform putting its full support behind HTML 5 as a standard and these elements were key in making HTML 5 a viable alternative.

**HTML 5 Page Structure** HTML 5 Attempts to simplified page structure starting with the Docutype and characterset. code <!doctype html> 

code HTML 4 Page Structure

HTML 5 Page Structure

HTML 5 simplified page structure is meant to eliminate coding errors and have cleaner code. The new page structure should work better for both devlopers and make it more machine readable. The best part of this new page structure is that it is backwards compatible so rendering should not be a problem.

**HTML 5 and Information Centers**
HTML 5 has elven years until it is officially a standard so it makes it unlikely to adopted by information centers since most are publically funded and standards compliance is apart of that funding. Further most library and information centers are using content management systems such as Durple. But, this is a narrow view of what HTML5 is capable of as a development platform. Information centers will have to support smartphone app development if it wants to stay relevant in a post web 2.0 environment. This makes HTML 5 an invaluable tool for information specialists to look at to develop apps. Further, HTML 5 is still a developing technology that libraries patrons will need assistance with and a working knowledge can be invaluable. But for the information specialist working on digital collections and imaging HTML 5 will be an invaluable tool that will allow new ways of presenting their content.
