HTML5: What’s Cool About It Justin Georges email@example.com Western Illinois University Libraries
HTML5: What is it? HTML5 defines the fifth major revision of the core language of the World Wide Web, HTML. HTML5 is currently under development. However, most modern browsers have some HTML5 support. Like its immediate predecessors, HTML 4.01 and XHTML 1.1, HTML5 is a standard for structuring and presenting content on the World Wide Web. Plug-in problems
HTML5: Some History HTML-Hyper Text Markup Language-is the fundamental blueprint of all Websites. When you visit a site, you see pages with text, photos, videos, and games. But your browser displays all that stuff because it downloaded a big chunk of HTML code that instructs it where to access that media and how to lay it out on a virtual page. http://www.pcworld.com/businesscenter/article/207653/html5_what_does_it_mean_for_you.html
“How can I start using HTML5 if older browsers don’t support it?” But the question itself is misleading. HTML5 is not one big thing; it is a collection of individual features. So you can’t detect “HTML5 support” But you can detect support for individual features, like canvas, video, or geolocation. HTML5: It’s not one big thing Taken from http://diveintohtml5.org/
HTML5: You don’t need to throw anything away HTML5builds on the success HTML 4. You don’t need to relearn things you already know. If your web application worked yesterday in HTML 4, it will still work today in HTML5. Taken from http://diveintohtml5.org/
Whether you want to draw on a canvas, play video, design better forms, or build web applications that work offline, you’ll find that HTML5 is already well-supported. Firefox, Safari, Chrome, Opera, and mobile browsers already support canvas, video, geolocation, local storage, and more. Even Microsoft — rarely known for blazing the trail of standards support — will be supporting most HTML5 features in Internet Explorer 9. HTML5: It already works Taken from http://diveintohtml5.org/
Tim Berners-Lee invented the world wide web in the early 1990s. He later founded the W3C to act as a steward of web standards, which the organization has done for more than 15 years. Here is what the W3C had to say about the future of web standards, in July 2009: Today the Director announces that when the XHTML 2 Working Group charter expires as scheduled at the end of 2009, the charter will not be renewed. By doing so, and by increasing resources in the HTML Working Group, W3C hopes to accelerate the progress of HTML5 and clarify W3C’s position regarding the future of HTML.

HTML5: Video format Still in the works for what video format will become the standard, right now just ogg and mp4 are the most popular. Apple & IE pushed=h.264 (portions of the H.264 technology are covered by patents) Ogg=another HTML5 video format option being pushed by the open source community, but the W3C is also concerned over patent issues. Google recently introduced a new video format, dubbed WebM, and open-sourced its technology in an effort to settle the matter. The key players can’t agree.

Steve Jobs vs. Flash (unstable CPU hog) Will flash go away? Flash is all over the web, but you have to have a plug-in to make it work. There is no way to do digital rights management in HTML5 Google supports it HTML5: What happens to flash?
Geo-Location The geo-location features allow users to share their current location with the site they are visiting. The feature uses a combination of GPS, WiFi, IP address and Bluetooth to determine the user's position. There are many opportunities for geo-location-capable browsers, including customized search results, location-specific maps and listings and a host of others. Users have to actively give permission to a site to obtain their location to prevent against abuse. HTML5: What has changed? Taken from http://mybroadband.co.za/news/internet/12127-Best-HTML5.html
Offline storage Offline storage is a lot like Google's Gears except without needing a plugin. This means that anything from user details to email can be stored locally and used by web applications. Work offline and sync to the cloud when you get internet access. Web storage Cookies are not suitable for large amounts of data, because they are passed on by EVERY request to the server, making it very slow and in-effective. In HTML5, the data is NOT passed on by every server request, but used ONLY when asked for. It is possible to store large amounts of data without affecting the website's performance.

Local file access This new capability allows web-based applications to access and manage files stored on a local hard disk. Users won't have to upload files to a remote server before being able to manipulate them. For example, a photo management application could be used to manipulate an image stored locally, or even view thumbnails, without needing to upload the image first. Drag and drop-have this capability with Gmail, where you can drag a file to the browser window to add as an attachment. HTML5: What has changed?

A few other neat features (keep an eye out for these) Edit content: selected portions of the page will be available to users to jot down notes and those notes will appear when they return to the site. Chat: API associated with HTML5 will let web developers set up a simple chat program. Users interact beyond limits of a comments section (similar to Meebo) New form input types and elements HTML5: What has changed?
Possibility of one icon that will open a window capable of any task imaginable. With growing popularity of online software packages (Office and Photoshop) html5 would allow offline use and seamlessly synchronizing new changes when a connection becomes available.

Should also speed the development of new kinds of websites for presenting magazines and newspapers on tablet computers. Libraries will love the new tags like <article> for marking articles or blog posts with additional citation information There’s an <aside> for attaching related content. These tags will define the relationship between pieces of content by enabling semantic identification.

Cookies Concerns about tracking Each browser has different privacy settings Software developers and the representatives of the World Wide Web argue that as technology advances, consumers have to balance its speed and features against their ability to control their privacy.
