Media formats supported by the HTML audio and video elements - HTML (HyperText Markup Language) | MDN The <audio> and <video> elements provide support for playing audio and video media without requiring plug-ins. Video codecs and audio codecs are used to handle video and audio, and different codecs offer different levels of compression and quality. A container format is used to store and transmit the coded video and audio (both together, the case of a video with a soundtrack). Many combinations of codecs and container formats exist, although only a handful of these are relevant on the Web. Different browsers do not support the same media formats in their implementations of HTML5 video and audio, mainly because of patent issues. The area of media formats on the Web has greatly suffered from patent law in many countries including the USA and EU countries (the notes on patents in this article is provided as-is and without any warranty.) WebM The WebM format is based on a restricted version of the Matroska container format. Gecko recognizes the following MIME types as WebM files: video/webm

Front-end development - RedTeamDesign World Wide Web Consortium (W3C) BIO: A vocabulary for biographical information Creators David Galbraith This document describes a vocabulary for describing biographical information about people, both living and dead. The BIO vocabulary contains terms useful for finding out more about people and their backgrounds and has some cross-over into genealogical information. The approach taken is to describe a person's life as a series of interconnected key events, around which other information can be woven. The BIO vocabulary defines a number of core classes and properties for describing biographical information: Figure: Biography Vocabulary Core Classes (PNG version, SVG version) At its heart the BIO vocabulary is concerned with people, their relationships and the events in their lives. The sequence of events and intervals build a timeline of history against which people and their relationships can be placed.

HTML5 Microdata Format Generator | Barry Ko Following up on a previous entry on the Microdata Format, I’ve created a completely free, for non-commercial purposes, Microdata Generator for some of the more popular item types: Books, Movies, People, Organizations and Companies, Stores, Restaurants, and Local Businesses. While there are other Microdata Generators and Creators out there, I haven’t found one that correctly nests multiple item types, or integrates the correct Hours of Operation (date/time) item property, which is essential for local businesses and restaurants. Furthermore, I’ve taken the extra step of giving you the option to include line breaks (for those who prefer the raw text format), the option to wrap the labels in a <span> tag, and the option to insert a class into the label span for custom css styling!
