Mobile Web Applications Current Status

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.



HTML Media Capture

This specification defines HTML form enhancements that provide access to the audio, image and video capture capabilities of the device.


Geolocation API Specification 2nd Edition

This specification defines an API that provides Web pages scripted access to geographical location information associated with the hosting device.


Indexed Database API

This document defines APIs for a database of records holding simple values and hierarchical objects.


Metadata API for Media Resources 1.0

This specification defines a client-side API to access metadata information related to media resources on the Web.


Mobile Web Application Best Practices

This document specifies best practices for the development and delivery of Web applications on mobile devices.

Group Notes


Device API Access Control Use Cases and Requirements

This document defines requirements for controlling access to device APIs, illustrated by corresponding use cases.


Device API Privacy Requirements

This document provides definitions, use cases, and requirements for making device APIs more privacy-friendly.


Device APIs Requirements

These are the requirements intended to be met in the development of client-side APIs that enable the creation of Web Applications and Web Widgets that interact with devices services such as Calendar, Contacts, Camera, etc.


Offline Web Applications

Offline Web Applications highlights the features in HTML 5 that address the challenge of building Web applications that work while offline.


Below are draft documents: Candidate Recommendations, 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.

Candidate Recommendations


Wake Lock API

This document specifies an API that allows web applications to request a wake lock. A wake lock prevents some aspect of the device from entering a power-saving state (e.g., preventing the system from turning off the screen).


The WebSocket API

This specification defines an API that enables Web pages to use the Web Sockets protocol for two-way communication with a remote host.

Other Working Drafts


Service Workers 1

This specification enables applications to take advantage of persistent background processing, including hooks to enable bootstrapping of Web applications while offline.


File API

This specification provides an API for representing file objects in web applications, as well as programmatically selecting them and accessing their data.


Web Workers

This specification defines an API that allows Web application authors to spawn background workers running scripts in parallel to their main page. This allows for thread-like operation with message-passing as the coordination mechanism.


IndieUI: User Context 1.0

Defines a set of preferences that users can choose to expose to web applications, and an API for user agents to access the preferences and listen for changes. Web applications can use this information to optimize the presentation without a requirement to target a specific device, operating system, or locale.


Mobile Accessibility: How WCAG 2.0 and Other W3C/WAI Guidelines Apply to Mobile

Mobile Accessibility: How WCAG 2.0 and Other W3C/WAI Guidelines Apply to Mobile” describes how the Web Content Accessibility Guidelines (WCAG) 2.0 and its principles, guidelines, and success criteria can be applied to mobile web content, mobile web apps, native apps, and hybrid apps using web components inside native apps. It provides informative guidance, but does not set requirements. It also highlights the relevance of the User Agent Accessibility Guidelines 2.0 in the mobile context.


MediaStream Capture Scenarios

This document collates the scenarios that are target use cases for the Media Capture API that enables access to media input capabilities for Web applications using Javascript.

Obsolete Specifications

These specifications have either been superseded by others, or have been abandoned. They remain available for archival purposes, but are not intended to be used.



Packaging on the Web

This document describes an approach for creating packages of files for use on the web. The approach is to package them using a new application/package media type. To access packages related to other files on the web, clients that understand packages of files look for a Link header or (in HTML documents) a element with a new link relation of package. Other formats may define format-specific mechanisms for locating related packages.


Geolocation API Specification Level 2

This specification adds the ability to retrieve a civic address, rather than coordinates, to the Geolocation API.


XMLHttpRequest Level 1

The XMLHttpRequest specification defines an API that provides scripted client functionality for transferring data between a client and a server, one of the core components of “AJAX”.


Permissions for Device API Access

This document identifies the permissions that are needed to use specific client-side APIs which grant access to sensitive data and operations.


Contacts Manager API

A system level API for managing the user's contacts that are stored in the system's address book.


Pick Contacts Intent

This specification defines an API that provides access to a user’s unified address book.


The Messaging API

This specification defines an API that provides access to messaging functionality in the device, including SMS, MMS and email.


The System Information API

This specification defines an API to provide Web applications with access to various hardware properties of the system which they are running on, including battery status, current network bandwidth.


Programmable HTTP Caching and Serving

This document defines APIs for off-line serving of requests to HTTP resources using static and dynamic responses. It extends the function of application caches defined in HTML5.
