Hi Adrian,

You're right, and I trust Karen and others from the group will find a way to alleviate your concerns. Maybe a definition for "open" could be added. Or linked to: I seem to remember the OBD group (or is it OKFN at large?) had written a definition for open data. Can you circulate the link?



> Adrian, thanks for your comments. I'll make a note to look at where "open data" is used in the report to see if we can clarify any confusion.
> As for the section on "rights" -- that was not intended to specify "copyright" but *any* rights based on ownership, contracts, policies, or law. We are adding some wording to try to make that clear, and I'll read through that part of the text to make sure that our statements are all about those rights in general.
