You almost have it! "However, I now see your real concern lies not in the infringement itself, but in the incidental usage by a third or forth party that could be extremely offensive, (vis. the Windows - nazi icon) litigious or downright embarrassing for all parties." Not quite. OCAL doesn't censor (much), in that we don't delete offensive material. The only "offfending" cliparts are copyright infringers, and these are removed from the library. Nudity, violence, and adult themed clipart are still available on the site, and these are marked as NSFW. For example, the swastika and any images of it are banned in Germany and are offensive to the German people (and many others), however a clipart of a swastika is acceptable as Public Domain on the OCAL library. The Windows icon isn't acceptable, as it is a copyrighted trademark. (We might be working on a set of tags so that German people aren't subjected to swastikas, but that is a large can of worms.) My concern is "unintended copyright breaches", by people who haven't done their research, trusting OCAL's statement of all PD clipart to be true. I have no solution as yet.

"The actual clipart content on open clipart library is Public domain." For me, it's about building trust..." I finally (click) get the gist of your argument. I must be getting old.. ;) >From practical experience, and a small amount of legal discussion with my old firm's patent and copyright lawyers, I believe that the issue might lie within the percentage, incidentality and frequency of 'exposure'. If memory serves, the 'percentage' of 'total' image should be no more than approx. 30%? but please don't quote me on that. 'Incidentality', obviously refers to the 'focus' of the image.. i.e. a rusty beer can in the off foreground of a landscape painting does not infringe, nor does anything that may happenstance be floating about (t-shirt, headset or book spine.) The third is even less likely to occur, IMO, echoed or repetitive use of the article within the artwork. Unless you're Escher, or Dali and you're illustrating some strange mirrored effect. However, I now see your real concern lies not in the infringement itself, but in the incidental usage by a third or forth party that could be extremely offensive, (vis. the Windows - nazi icon) litigious or downright embarrassing for all parties. I'm thinking, child's first birthday invitation to Grandma... Which, come to think of it, (click), now explains the 'safe' file button on the 'uploads' page, which I blithely assumed to mean 'virus checked' or some such, in reference to animated or script executable SVG files. (i.e. Adobe Flash etc.) Insurance against 'non-safe' third party files is a very interesting, but very real dilemma, and I can understand your queried brow. I'm at a loss but will endeavor to assist if I may. Perhaps, again, a large part of this could be handled by better/clear communication artist to user? I'd happily sign a declamation prior to submitting work. "I hereby state that such and such.." >> ... I hope you didn't take my reply as a "get back there!" ...
