Hi all I'm having a little trouble determining about this <a href="http://www.openclipart.org/detail/postgresql-logo-by-abdobelk">http://www.openclipart.org/detail/postgresql-logo-by-abdobelk</a> It's a logo, and I assumed that it was copyrighted. When I looked into it though, it becomes complicated to identify the licence that the artwork is licenced under. The software is licenced under and "almost" BSD licence. <a href="http://www.opensource.org/licenses/postgresql">http://www.opensource.org/licenses/postgresql</a> . However, I can find a few places where it looks like the artwork is CC-BY-SA. <a href="http://www.postgresql.org/community/propaganda">http://www.postgresql.org/community/propaganda</a> I think their intent is to make it as open as possible, (which is good intent), but "technically" the wording of those licences is still not open enough to include THEIR LOGO in our PD / CC0 Library. Other places where a licence is mentioned: Copyright © 1996 – 2011 PostgreSQL Global Development Group (on every page) <a href="http://pgfoundry.org/projects/graphics/">http://pgfoundry.org/projects/graphics/</a> What are your thoughts on this? Allow or disallow? -- Cheers Chovynz
