Widgets 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.

Group Notes

Below are draft documents: 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.

Other Working Drafts


Widgets 1.0: The Widget Landscape (Q1 2008)

This document surveys a group of market-leading widget user agents with the aim to inform the requirements of the Widgets 1.0: Requirements document. The survey exposes commonalities and fragmentation across widget user agents, and discusses how fragmentation currently affects, amongst other things, authoring, security, distribution and deployment, internationalisation and the device-independence of widgets. The document concludes by making a set of recommendations on what aspects of widgets require standardization to reduce fragmentation to ultimately standardize a cross-platform widget solution.

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These specifications have either been superseded by others, or have been abandoned.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.



Packaged Web Apps (Widgets) - Packaging and XML Configuration (Second Edition)

This specification standardizes a Zip-based packaging format for software known as widgets. Widgets are client-side applications that are authored using Web standards, but whose content can also be embedded into Web documents.


Widget Access Request Policy

This specification defines the security model controlling network access from within a widget, as well as a method for widget authors to request that the user agent grant access to certain network resources or sets thereof.


XML Digital Signatures for Widgets

This document defines a profile of the XML-Signature Syntax and Processing specification to allow a widget resource to be digitally signed.


The 'view-mode' Media Feature

This specification defines a media feature to match the different visual presentation modes that can be applied to web applications and thereby apply different styling based on these different modes using CSS Media Queries.


Widget Interface

This specification defines an application programming interface (API) for widgets that provides, amongst other things, functionality for accessing a widget’s metadata and persistently storing data.
