This is the home of the bleeding edege version of the picture element spec.
It's where we do our crazy experiments before the spec over to the W3C.
If you found a problem with the spec, no matter how small, please file a bug.
Proposals for normative changes to the specification should take place on the RICG mailing list.
It's on github pages.
We keep an unstable Editor's Draft on the W3C's Mecurial Server. As much as possible, we try to make sure that this snapshot has the current concensus of the Community Group.
Join the RI Community Group and help us make the Web a better place ... for images :)
