This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title
links to the most recent version of a document.

Completed Work
W3C Recommendations have
been reviewed by W3C Members, by software developers, and by other
W3C groups and interested parties, and are endorsed by the
Director as Web Standards. Learn more about the W3C Recommendation
Track.
Group Notes are not standards and do not
have the same level of W3C endorsement.

This document describes the Media Fragments 1.0 specification. It specifies the syntax for constructing media fragment URIs and explains how to handle them when used over the HTTP protocol. The syntax is based on the specification of particular field-value pairs that can be used in URI fragment and URI query requests to restrict a media resource to a certain fragment.

This document defines the Ontology for Media Resources 1.0. The
term "Ontology" is used in its broadest possible definition: a core
vocabulary. The intent of this vocabulary is to bridge the different
descriptions of media resources, and provide a core set of
descriptive properties. This document defines a core set of metadata
properties for media resources, along with their mappings to elements
from a set of existing metadata formats. Besides that, the document
presents a Semantic Web compatible implementation of the abstract
ontology using RDF/OWL. The document is mostly targeted towards media
resources available on the Web, as opposed to media resources that
are only accessible in local repositories. side implementations.

This document introduces a series of scenarios and a list of requirements
guiding the work of the W3C Audio Working Group in its development of a web API
for processing and synthesis of audio on the web.

Drafts
Below are draft documents:
Candidate Recommendations, Last Call Drafts, other Working Drafts.
Some of these may become Web Standards through the W3C Recommendation Track
process. Others may be published as Group Notes or
become obsolete specifications.

2013-05-16
|
This document defines a set of APIs that allow local media,
including audio and video, to be requested from a platform, media
to be sent over the network to another browser or device implementing
the appropriate set of real-time protocols, and media received from
another browser or device to be processed and displayed locally.

This specification describes a high-level JavaScript API for
processing and synthesizing audio in web applications. The primary
paradigm is of an audio routing graph, where a number of AudioNode
objects are connected together to define the overall audio rendering.
The actual processing will primarily take place in the underlying
implementation (typically optimized Assembly / C / C++ code), but
direct JavaScript processing and synthesis is also supported.
