Understanding the GNU Free Documentation License

Posted by wktd - November 20th, 2008

  • I have a website and I want to use articles from wikipediea on it. I had some problems understanding the limitations of the GNU and I want to be on the safe side. If I use a complete article without editing it - is it enough to give credit to wikipedia ( with the appropriate format) Does this affect the of my site? Do I need to share part of my site? Thanks, Feel free to ask clarifications.


  • troy1... Here's the Wikipedia page on 'insurance'. A search for a random line of exact text on that page returns a number of sites that use Wiki content as the basis of their content, supplemented by PPC ads (such a format, devoid of original content is, in the opinion of webmasters, considered spammy and less desirable than pages with useful original content in addition to Wiki content): "Property and liability insurance policies cover persons and not property or operations. Although the" ://www.google.com/search?q=%22Property+and+liability+insurance+policies+cover+persons+and+not+property+or+operations.+Although+the%22 If you go through those results looking at the bottom of the pages, you'll see various formats for attribution of the content to Wikipedia, from: "2006 protect your best. . Some information taken from Wikipedia.org" http://www.protectyourbest.com/ ...to the more correct format: "This article provided by Wikipedia, The Free Encyclopedia. YourArt.com is not responsible for its contents. This article is licensed under the GNU Free Documentation License. Source article can be found at http://en.wikipedia.org/wiki/insurance. 1997-2006 YourArt.com, Division of YourArt, Inc. ." http://www.yourart.com/research/encyclopedia.cgi?subject=/insurance The latter format allows for clarity in noting what is Wiki content and what other material on the page falls under your . The GNU does not require that you share a portion of your site. If anything is unclear or needs further elaboration, let me know... sublime1-ga


  • hi, I don't like this answer at all.... The fact that other people use it - this is not enough. I want to understand the GNU license. In one site they wrote" Some information taken from Wikipedia.org " This is no OK according to the GNU license: http://en.wikipedia.org/wiki/Wikipedia:Text_of_the_GNU_Free_Documentation_License 4. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: * A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. * B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. * C. State on the Title page the name of the publisher of the Modified Version, as the publisher. * D. Preserve all the notices of the Document. * E. Add an appropriate notice for your modifications adjacent to the other notices. * F. Include, immediately after the notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. * G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. * H. Include an unaltered copy of this License. * I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. * J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. * K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. * L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. * M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. * N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. * O. Preserve any Warranty Disclaimers.


  • troy1... Yes, you seem to agree with the point I made, without acknowledging that I made it, with regards to the first example I cited: "2006 protect your best. . Some information taken from Wikipedia.org" This is a poor attribution ("not OK"), and, however common, is less than acceptable, though never challenged, that I'm aware of. "This article provided by Wikipedia, The Free Encyclopedia. YourArt.com is not responsible for its contents. This article is licensed under the GNU Free Documentation License. Source article can be found at http://en.wikipedia.org/wiki/insurance." This example, on the other hand, is very acceptable, and quite common. In truth, I would consider it an impossible challenge to find any example of a Wikipedia attribution that is better written, based on my considerable experience in researching precisely this topic in the last 3 years. If you would prefer to complicate the issue beyond common practice, I can only tell you that I have not come across any examples of the details you seem to be expecting in 3 years of exploring Wikipedia attributions. If you would prefer it, I can ask the editors to remove my answer so that other researchers will have the opportunity to attempt to satisfy your interest in the unneccessary complexities you seem adamant in satisfying, however I'm reasonably confident that actual examples of same will be next to impossible to find. As you wish...let me know your thoughts... sublime1-ga


  • P.S. The following Google search, with 19,900,000 results, may assist you in realizing the usual nature of Wikipedia attributions: "This article is licensed under the GNU Free Documentation License" ://www.google.com/search?q=%22This+article+is+licensed+under+the+GNU+Free+Documentation+License%22 These citations include sites such as the acknowledged partners of Google - Answers.com - who provide the 'definition' for words which might have one in a Google search, such as the one for 'destiny': destiny ://www.google.com/search?q=destiny 'destiny' definition on the results page: ://www.google.com/url?sa=X&oi=dict&q=http://www.answers.com/destiny%26r%3D67 One such article on answers.com, on the topic of the GFDL, or 'GNU Free Documentation License',states, at the bottom, simply: "This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "'GNU Free Documentation License'". http://www.answers.com/topic/gnu-free-documentation-license It simply isn't more complicated than that. Sorry if that disappoints.


  • hi, I don't understand the relevancy of the clarification you posted Please focus on what i asked.


  • Here's what you asked: "If I use a complete article without editing it - is it enough to give credit to wikipedia ( with the appropriate format)"? Short answer: Yes. Relevancy of clarification: If 19,900,000 sites, including at least one selected by Google itself (the 'do no evil' company) as a partner, use exactly the same simple format, it seems reasonable that it constitutes an 'appropriate' format. "Does this affect the of my site?" Short answer: No. An example was provided on how to separate the citation for the Wikipedia content from the citation for your site's content, repeated here: "This article provided by Wikipedia, The Free Encyclopedia. YourArt.com is not responsible for its contents. This article is licensed under the GNU Free Documentation License. Source article can be found at http://en.wikipedia.org/wiki/insurance. 1997-2006 YourArt.com, Division of YourArt, Inc. ." http://www.yourart.com/research/encyclopedia.cgi?subject=/insurance "Do I need to share part of my site?" Short answer: No. There are too many examples of sites which don't, and I've never seen one which did. "The fact that other people use it - this is not enough." Agreed. Relevancy of Clarification: The fact that 19,900,000 unique sites use a specific IS enough, in contrast to the number (2) of results for the example of a poor citation which I provided: "Some information taken from Wikipedia.org" ://www.google.com/search?q=%22Some+information+taken+from+Wikipedia.org%22 To me, it seems that your questions have been answered. If you disagree, let me know and I'll ask the editors to remove my answer, or point out to me exactly where on this page you asked a question that I didn't address.
