Hi. Just an idea about the buttons: Please make it more international, by using symbols instead of text (like Attribution, Share-Alike). Regards-- 23:18, 16 February 2007 (CET)

Should we avoid duplicating Creative Commons work? - and focus on icons for free/libre content? - e.g. CC-By and Public Domain are arguably non-free/libre - as both allow derived works (such as translations and localisations) to be released under more restrictive licenses. Kim 13:48, 5 March 2007 (CET)

I strongly disagree. There is no higher degree of freedom than the absence of copyright. To argue that the works of Shakespeare are not libre because they are not under a copyleft license is bizarre to me. This is also in line with the definition, which permits copyleft, but does not require it.--Erik Möller 15:45, 5 March 2007 (CET)

Thanks Erik. Some comments: Discussion of copyleft

Thinking About Buttons

The buttons, in my opinion, still need a little more work. What we need to do is provide some HTML through which people can include the buttons on their sites. This HTML needs to include a link to the button, which is easy enough, but it should also include the necessary RDF and a link, somewhere back to the deed on the CC site. This should be, I think, in addition to the link to a license-specific page in our wiki. I'm thinking what we should do is create an image map with a small area (it could even just be a couple pixels) that links to the CC site and the rest can link to us.

There is a thread that happened on the CC-Community mailing list that is worth reading over first. The thread also raised some interesting issues about about using the CC icons instead of the letters which I definitely think we should do. If someone can help with the the new buttons, I could probably sit down and hack out some sort of solution in terms of the image maps. Benjamin Mako Hill 22:22, 8 April 2007 (CEST)


You should get these put into MediaWiki, and when administrators start up their wiki, create a way for them to choose between the logos, as well as the license. 04:21, 17 April 2007 (CEST)


Hi, does anyone have an idea why <gallery perrow="3"></gallery> doesn't work here? --Kjoonlee 20:50, 18 June 2007 (CEST)

Maybe it's due to version differences.. The English Wikipedia uses MediaWiki 1.11alpha (r22970) and "perrow" is supported there, but this site uses 1.9.0. --Kjoonlee 19:50, 22 June 2007 (CEST)

Equal treatement for "PD" please.

Would it be too much trouble to ask for buttons with "PD" in the same size letters as the other buttons have (and perhaps "Public Domain" underneath there in small print for some variants, like there are for the others). No reason to not have such. The current ones with Public and Domain in same size on different rows looks very busy to me. -- Cimon Avaro 12:26, 10 July 2007 (CEST)

An svg version would also be nice ... we could develop our own variants/colors/sizes. Does this exist? or should I (or a real artist) try my hand at tracing in Inkscape again? --Inkwina 12:38, 10 July 2007 (CEST)

License of buttons?

I see that the main logo and first set of buttons are PD but the rest have no license info. Am I just to assume they are CC-BY-2.5? -- 19:25, 1 May 2010 (UTC)


CC0 (Creative Commons Zero) buttons are needed. CC0 is a Public Domain dedication plus a very simple license without any requirements. The latter is for jurisdictions that don't accept PD dedications. -- Sloyment 13:35, 18 May 2010 (UTC)

METAFONT license icons

Is there a copy of license icons in METAFONT? I would like to use them in books created using TeX (not LaTeX). -- 03:41, 17 November 2010 (UTC)

I have written a program to do the logo in GF-Magick. It is not perfect; please fix it if you want to fix it. Here is the program:

% Logo for "Free Cultural Works"
% This logo and the program to generate it are public domain.

input gfmagick;



def gradient(expr xx,yy,zz,zzz) =
  special "-size";
  special "=#0x#0";
  numspecial round(xx);
  numspecial round(yy);
  numspecial 0;
  special "=gradient:rgba(#0,#0,#0,#2)-rgba(#0,#0,#0,#2)";
  numspecial round(255*redpart(zz));
  numspecial round(255*greenpart(zz));
  numspecial round(255*bluepart(zz));
  numspecial alphapart(zz);
  numspecial round(255*redpart(zzz));
  numspecial round(255*greenpart(zzz));
  numspecial round(255*bluepart(zzz));
  numspecial alphapart(zzz);
  numspecial 0;

def padding(expr xx,yy) =
  special "-gravity";
  special "Center";
  special "-extent";
  special "=#0x#0";
  numspecial round(xx);
  numspecial round(yy);
  numspecial 0;
  special "+gravity";

def sequence_multiply =
  special "-fx";
  special "u*v";

def do_layer(expr radius,color,quadrant,grad) =
      pickup pencircle scaled (radius*large_circle);
      draw (0,0);
      z1=(0,0); z2=quadrant*half_size; z3=(xpart z2,0); z4=(0,ypart z2);
      unfill z1--z3--z2--z4--cycle;
    if grad:


vardef Red = rgb(1,0,0) enddef;
vardef Orange = rgb(1,1/2,0) enddef;
vardef Yellow = rgb(1,1,0) enddef;
vardef Green = rgb(0,2/3,0) enddef;
vardef Blue = rgb(0,0,1) enddef;

Terry Hancock designs, AIGA dude.

I like the Terry Hancock designs. I particularly like that they almost seem to be based on the Microgramma extended or Eurostile extended capital O. However, I think that the little "attribution" dude looks a bit odd. Perhaps you should use the "Toilets - Men" figure from the AIGA sign designs -- they're in the public domain, and generally more familiar (at least to U.S. viewers; perhaps not elsewhere), and they're available in EPS format, which is relatively easy to convert to SVG. (clarification: I'm not getting "public domain" from "available for all to use, free of charge" on AIGA's website, I'm getting it from the fact that the images were designed in collaboration with the US Dept. of Transportation, making them public domain Also: there's already an SVG) 06:43, 15 June 2011 (EDT)
