Version 1.1 of the definition has been released. Please help updating it, contribute translations, and help us with the design of logos and buttons to identify free cultural works and licenses!

Logos and buttons

From Definition of Free Cultural Works
Jump to: navigation, search

The official logo of the Definition of Free Cultural Works was designed by Marc Falzon, and placed in the public domain:

An SVG copy can be found here

The logo represents both the diversity of human culture, and the openness and freedom to interact with free cultural works.

Please feel free to create derivatives of this logo, and upload them to this wiki.

Buttons

Please note that simply adding a button does not license your work in any way. You have to clearly state which license you use. One way of doing that is making the link point to the license, and having an explicit statement "This work is licensed under the ... license" below the work. To ensure that the page is indexed by search engines with the appropriate "usage rights," use rel="license" in the HTML code for link.

AMYMADE's buttons

The following set of buttons were designed by AMYMADE with the support of the Free Software Foundation and represents our official recommendation:

CCBY black.png CCBYSA black.png GFDL black.png GPL black.png LGPL black.png PUB black.png

CCBY red.png CCBYSA red.png GFDL red.png GPL red.png LGPL red.png PUB red.png

CCBY yellow.png CCBYSA yellow.png GFDL yellow.png GPL yellow.png LGPL yellow.png PUB yellow.png

These buttons are in the public domain. Which color you use is your choice; we suggest red for music, black for science and software, and yellow for everything else.

Rational's buttons

The following set of buttons were designed RationalBob using Adobe Illustrator:

Small buttons

This is the cleanest set so far and it comes with a template.

Inkwina's icons

The svg versions CC-BY-SA.svg and Image:GNU_FDL.svg do not display well online. They where created using Inkscape, and the SVG hasn't been cleaned up. But the Blank button.svg can be used to generate more buttons. --Inkwina 15:01, 22 February 2007 (CET)

License Classification Icons by Terry Hancock

These are meant to be generic analogs to Creative Commons' "license deed" icons (The CC icons are subject to trademark. I intend these icons to be different enough to avoid any trademark dispute or confusion, but similar enough to facilitate communication). Unlike the CC icons, these do not map to particular detailed license modules, but rather indicate general classes of licenses.

So far, these are the only ones I could think of needing for free licenses, but I am interested in hearing suggestions for what additional requirements we ought to have icons for:

Fd sq icon pd.svg "Public Domain" or "No Requirements".

Fd sq icon by.svg "Attribution" requirement.

Fd sq icon sa.svg "Copyleft" or "Share Alike" requirement.

Fd sq icon sc.svg "Source Code" requirement.

Fd sq icon drm.svg "No DRM/TPM" requirement.

Fd sq icon hard.svg "Production Copyleft" (a proposal for effective copyleft on hardware designs)

I also have some "non-free" icons for license comparison purposes, along with color-coded versions of the above (black="null", green="maximal individual freedom", blue="maximal maintenance of freedom", yellow="semi-free or free within a limited domain", red="not free at all"). I recommend these icons for use where free and non-free licenses will be compared with each other:

Fd sq icon pd.svg "Public Domain" (same as above)

Fd sq icon by grn.svg "Attribution"

Fd sq icon sa blu.svg "Copyleft"

Fd sq icon sc blu.svg "Source Code"

Fd sq icon drm blu.svg "No DRM/TPM"

Fd sq icon nc.svg "Non-Commercial"

Fd sq icon nd.svg "Non-Derivative"

Fd sq icon arr.svg "All Rights Reserved"

Here are a set of icons representing the Four_freedoms:

Fd sq icon use.svg Freedom #1: Use/Performance

Fd sq icon study.svg Freedom #2: Understanding

Fd sq icon copy.svg Freedom #3: Copying and Distribution

Fd sq icon add.svg Freedom #4: Derivatives

License description pages

For each license, we will try to create a description page. Here are some examples:
