W3C:

2008-04-14: The Web Application Formats Working Group has published four Working Drafts related to Widgets 1.0: The Widget Landscape (Q1 2008), Packaging and Configuration, Digital Signature, and Requirements; these are the First Public drafts for Digital Signatures and Landscape. Widgets are small client-side Web applications for displaying and updating remote data, that are packaged in a way to allow a single download and installation on a client machine, mobile phone, or mobile Internet device. "Landscape" reviews commonalities and fragmentation across widget user agents and explores how fragmentation currently affects, amongst other things, authoring, security, distribution and deployment, internationalization and the device-independence of widgets. "Packaging" defines a Zip-based packaging format and an XML-based configuration document format for widgets. "Digital Signature" defines a profile of the XML-Signature Syntax and Processing specification to allow a widget resource to be digitally signed. "Requirements" lists the design goals and requirements that specification would need to address in order to standardize various aspects of widgets. Learn more about the Rich Web Client Activity.
