These files have changes by non-Googler. What header should we add? Just replace "Google Inc" with "The Chromium Authors" in the usual header? 195843 5 abarth 2010-03-03 18:24:21 -0800 > These files have changes by non-Googler. What header should we add? Just > replace "Google Inc" with "The Chromium Authors" in the usual header? In the past, folks in the WebKit community have expressed uncertainty about attributing copyright to "The Chromium Authors." My understanding is that this is actually ok legally, but we might want to be more specific if its feasible. There are a few options: 1) Attribute copyright explicitly to everyone in the Chromium AUTHORS file (i.e., by listing them in the copyright notice). 2) Use the revision history of this file to filter that list down to those who have actually contributed to this file. 3) Convince the WebKit community that "The Chromium Authors" is a find entity to which to attribute copyright. 195845 6 abarth 2010-03-03 18:24:42 -0800 s/find/fine/ 195856 7 dglazkov 2010-03-03 18:55:11 -0800 Don't feel blocked by the name issues.

I supposed WebKit/chromium was in the include paths and third_party/npapi was extracted to there. I changed it to WebBindings.h. It seems better. 196080 10 49991 dglazkov 2010-03-04 07:42:18 -0800 Comment on attachment 49991 Proposed patch (rev.2) I think we Adam mentioned "Chromium Authors", he meant it as a more long-term solution.
