Hi, tl;dr:
Q1: Are the two images actually licensed as "GPLv2 or any later version"? Q2: Who would I have to ask for permission to use the images in a GPLv2+ incompatible licensed work (CC BY/BY-SA)? I wrote some custom dissectors for my master's thesis and want to illustrate the workflow. Ideally, I'd like to include two images from Wireshark, namely * Wireshark logo: image/wslogo.eps https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob_plain;f=image/wslogo.eps;hb=HEAD * WS Document icon: image/wiresharkdoc.ico https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob_plain;f=image/wiresharkdoc.ico;hb=HEAD and listing their git URL in my references. In my case, I think that usage exceptions (Germany) for quotation do not apply, since the artwork is used primarily for illustrative purposes and not as reference that is discussed in depth in the text (If I were to discuss a book cover, I could surely cite it. If I used that cover only as the opener (illustration) for my chapter, I'd need the permission to use it for that purpose) The thesis will be published open access as CC BY 4.0 or CC BY-SA 4.0 (I can choose) via the university library. However, Wireshark is (mostly) GPLv2+ and the artwork has no separate license saying that it diverts. So, formally, I would like to include GPLv2+ licensed material into CC BY or CC BY-SA material, and I have doubts that this is allowed :/ Since the thesis is written in LaTeX, the images are included in the final PDF, i.e. distribution of the PDF would constitute a distribution of the images also. What *is* allowed is: * Include CC BY 4.0 licensed material in GPL material (add author to AUTHORS file, add copy of CC license) https://www.gnu.org/licenses/license-list.en.html#ccby * Include CC BY-SA 4.0 material into GPLv3 (v3 only!) material (add author to AUTHORS file, add CC license, GPLv3 declared "BY-SA" compatible) https://www.gnu.org/licenses/license-list.en.html#ccbysa https://creativecommons.org/share-your-work/licensing-considerations/compatible-licenses What *is not* allowed (IMO): * Include GPL material into CC BY material, because access and rights to the GPL code would be "lost" * Include GPL material into CC BY-SA material. Doesn't work either, since BY-SA is weaker than GPL. There is also the possibility to get specific permission from the copyright holder, i.e. adding "Wireshark artwork [98][99] used with permission"-alike to the figure caption. Who would be that person to ask? However, I don't yet understand how Wikipedia (CC BY-SA 3.0) managed to show the Wireshark logo legally: https://en.wikipedia.org/wiki/Wireshark Maybe CC only applies to the text, not to the image? Could I do the same? For example - licensing my workflow illustration under GPLv3; derived work, includes Wireshark logos - include figure in CC BY/BY-SA text, add to caption "Figure licensed as GPLv3; Wireshark logos [98][99] licensed as GPLv2 or later" Help is much appreciated, cheers, -- panic ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@wireshark.org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe
