The IndieUI Working Group is no longer chartered to operate. The scope of its work are expected to be taken up in several other Working Groups:
- Web Platform may develop device-abstracted events similar in scope to IndieUI: Events;
- CSS may express some of the context properties from IndieUI: User Context as Media Queries;
- ARIA may build a module of additional context properties from IndieUI: User Context.
Resources from the IndieUI remain available to support long-term institutional memory, but this information is of historical value only.
Proposals/KeyValueProperties
From Independent User Interface
This is a restructuring of the User Context properties proposed by Rich and Andy, to execute ACTION-43. The goal of this exercise is simply to show how that set of proposed properties would look when expressed as key / value pairs, not to editorialize on the properties themselves. I have stayed as close to original property names as possible, but in some cases did split properties into multiple related ones.
