OK, the mailing list seems to be working, and we have 11 participants representing 8 W3C member organizations. I expect more will join presently, but that's enough to get started. Our charter says... "In the first phase, the WG will evaluate requirements ..." -- http://www.w3.org/2003/12/swa/dawg-charter Let's start with use cases. What's a use case? In some sense, we get to decide that together. But there is a fair amount of precedent, and we shorten the distance to our readership if we harmonize with the existing usage of the term. Surfing for a few minutes yielded the following definition, which appeals to me: "A use case describes the use of a system from start to finish. Use cases focus attention on aspects of a system useful to people outside of the system itself. [...] At the end of a use case value has been provided to the user who initiated it. A use case captures a requirement the user places on the system." -- http://c2.com/cgi/wiki?UseCase see also: User Story, which is a more constrained term from Extreme Programming... http://c2.com/cgi/wiki?UserStory The ideal use cases will -- command consensus of this Working Group as a description of a problem we intend to solve (or: solve a part of) -- clarify one or more requitements -- still be relevant when we're at last call, deciding whether we think the spec is done -- engage potential users of our technology and convince some of them to closely review our spec -- be clear and engaging enough to get picked up by journalists and copied into trade press stories Let's try to do brainstorming on use cases in email so that by our late-April face to face meeting, we can be discussing them in substance: clarifying them, selecting a few to write up nicely, starting to get a handle on the words we're using to capture requirements, and the like. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ see you at the WWW2004 in NY 17-22 May?
