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

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.
