Content licensing

While open source software commonly uses the GFL or similar license, text-based and multimedia content (like that found on Appropedia, Wikipedia, or open-licensed blogs) is typically licensed under:

• A Creative Commons license: Open license options are Creative Commons Attribution (CC-BY) and Creative Commons Attribution ShareAlike (CC-BY-SA). CC-BY-SA is used for Appropedia and Wikipedia. Other options exist, namely adding the Non-commercial and/or No derivatives clauses, but this is no longer considered an open or free (libre) license.
• GFDL (GNU Free Document License): An older license from the GNU Foundation, formerly used for Appropedia and Wikipedia.
• Lesser known licenses such as the Free Art License.^W
