If I have posted my own &quot;homebrew&quot; content on RPG.SE, and plan to publish it (after revising based on feedback), what credits am I required to give? I have posted numerous homebrew features on Role-playing Games Stack Exchange, and I have used advice gotten from that site to balance most of them. If, one day, I publish the subclass, would I be required to give any or all of the following credits? To the RPG.SE website as a whole To the individual users that gave feedback Just to the users whose feedback I used Or would I not be required to give any credit?
It's complicated You still own your own posts First off, you own everything that you originally created. Posting it on Stack Exchange doesn't affect your rights to your own content. Incorporating suggestions If you copy any of the text from posts that were created by others, you must comply with the CC BY-SA license. The exact version will depend on when the content was posted, and can be viewed by clicking the &quot;Share&quot; link or viewing the post's timeline via the clock icon on the left. Currently, new posts are licensed under CC BY-SA 4.0, which requires you to (basically) provide attribution with the creator's name, a link back to the content, and an indication of whether changes were made. A more detailed description of the exact requirements is here. You would also be required to license the work that you incorporated it into under the same license. However, game mechanics aren't copyrightable. If you merely used mechanics suggested in the posts without actually using the actual creative expression (for instance, names or description text) from the posts, you would not be required to provide any attribution or use any particular license, because you didn't use any copyrightable material from the post. A thank-you would still be nice All that said, it's still a nice thing to do to provide some sort of informal thanks to those who provided valuable assistance, even when you're not legally required to do so.
I believe the author has published it online. I agree. It is posted at his publisher's website. However, I am unsure if I'm allowed to read it. This answer assumes you are in jurisdiction whose copyright laws is based upon the Berne convention (i.e. the civilized world + USA). Assuming it was the author published it online, it is perfectly legal to read it. Technically, the author is performing his work by putting it online, and by reading it, you are just enjoying his performance. Also, if you are in a jurisdiction with an explicit exception from copyright for personal use, or where fair use allows making copies for personal use, it would also be legal to download it, or to print it on paper (but for personal use only). As for downloading and printing for non-personal use - that is not legal in Berne jurisdictions.
You automatically have copyright protection for what you create. A collection of numeric answers to math equations probably would not qualify (lack of requisite creativity), but certainly anything that counts as a "paper" is protected.
I believe you have just misunderstood what you paid for. Blizzard's End User License Agreement says: Your use of the Platform is licensed, not sold, to you, and you hereby acknowledge that no title or ownership with respect to the Platform or the Games is being transferred or assigned and this Agreement should not be construed as a sale of any rights. It also says: Blizzard may change, modify, suspend, or discontinue any aspect of the Platform or Accounts at any time, including removing items, or revising the effectiveness of items in an effort to balance a Game. Blizzard may also impose limits on certain features or restrict your access to parts or all of the Platform or Accounts without notice or liability.
Can a system include such information? it is surely technically possible. Would it be a violation of copyright? That depends. First of all, any such information can be included if the copyright holder has granted permission, probably in the form of a license. But in that case this question would probably not have been asked. I therefore assume that no permission has been granted. (It doesn't matter if a request was made and the answer was &quot;no&quot;, a request was made but ignored, or no request was ever made. No permission is still no permission.) The names of fictional locations are nor protected by copyright. Including, say, &quot;Rivendell&quot; or &quot;Hobbiton&quot; in the selection list for a timezone setting would not infringe the copyrights held by the Tolkien estate. But a map is a different thing. If the OS includes and can display a map of a fictional region, one that is copied from or based on a map published with the fiction, or by some third party, then that would almost surely be copyright infringement, and the copyright holder could choose to sue for infringement. S/he might choose not to sue, but that is a risky gamble to take. If this is in the US, statutory damages could be awarded, and could intheory go as high as $150,000, although they are not likely to be as high as that, that is just the maximum legal limit (per work infringed, not per copy). The standard is whatever amount the court thinks &quot;just&quot;, up to the maximum. (If proof of willful infringement is not made, the upper limit is $30,000, still a sizable sum.) If the OS designer created the map independently, using names from the fiction, but not otherwise basing it on the fiction, and in particular not imitating any map created by anyone else, then it may well not be infringement, but it would still be wise to consult a copyright lawyer. The question would be more helpful if it made clear just what would be hypothetically included in the OS, and to what extent it would be based on someone else's work. There is also the question of why someone would want to include fictional places, but that really doesn't change the legal issue.
I'm wondering whos responsible for this code if people start using it? The user. Can the people using it that think its under GPL in any way get in trouble for it or be made to remove it from their projects? Yes, they can be sued (successfully) for copyright violation. It’s not enough that you think you have permission from the copyright holder - you actually have to have permission. The law places the onus on the copier to seek out and get permission from the copyright holder. In theory, someone deceived in this way could sue the repo poster(s) for misrepresentation, however, there are practical issues about finding them, having them in an accessible jurisdiction and if they are judgement proof. Copyright law was created to protect physical books and paintings - it doesn’t really fit with digital methods of reproduction but it is the law. It doesn’t matter that complying with it can be hard bordering on impossible - comply with it you must.
In general this kind of brief literary reference is not unlawful, and such things occur in both novels and commercial games with some frequency. Making such a reference a major part of the plot, such as by using a name from a previous work as a major character, particularly if other aspects of that character are also used, is far more likely to cause a problem. In the united-states this would be a matter of fair use. In general, when only a very small part of the source work is used, such a a single name; where the use is &quot;transformative&quot;, that is used for a rather different purpose than in the source work; where the use does not harm the market for the original work; and where the use does not serve as a replacement for the original, it is likely to be held to be fair use. But fair use decisions are always fact-dependent, and are made case-by-case, so it is hard to be absolutely sure of one in advance. But the kind of literary reference described in the question is very unlikely to be held to be copyright infringement.
In Germany, there is no concept that corresponds directly to public domain. You automatically hold the Urheberrecht (~ copyright) for all creative works that you make, and it can't be given up or transferred (§29 UrhG). The work only enters the Gemeinfreiheit (~public domain) 70 years after your death. You can however license Verwertungsrechte (economic usage rights). When you make creative works in the course of employment (see §43 UrhG), your employer automatically gets the Verwertungsrechte necessary in the context for the work, which is typically an exclusive right (no one else, not even you, can use the work). Your are not in an employment relationship with your school, so it has no rights to your works and cannot prevent you from publishing them on copyright grounds. When you see advice on the internet to check with your school first, that is U.S.-specific advice. Since you're still a minor (7–17), you only have limited capacity to enter contracts or legal transactions (bedingte Geschäftsfähigkeit). While you are able to make transactions involving your own means (e.g. buying something with your pocket money) or make transactions that are only to your benefit (such as accepting a gift), other transactions are schwebend unwirksam (~ pending ratification), until your parents agree. The relevant law is in §107 and §108 BGB. This is a problem with open source licenses. If you publish software under a license, this license is schwebend unwirksam. Someone might start using the software under the license. But then if your parents refuse ratification, the license would be invalid, and everyone would have to stop using your software and destroy any derivative works they made. This is a bit of a problem, especially since open source licenses are otherwise assumed to be irrevocable. So if you want to offer a license (including open source licenses), please give legal certainty to the recipients of the license and ask your parents for their consent first, possibly even in writing. Per §107 BGB, the license you offer with their consent will be valid.
