Is it infringement to give a link to a copyrighted file? Does posting a link to a copyrighted file, such that accessing the linked file would constitute infringement, but where the file itself is not on my servers, constitute any sort of crime or infringement?
In Canada, no: linking does not reproduce any part of the original. In Sweden, Spain and according to the EU, no: communicating a link does not communicate anew the work to the public. In the US, it isn't as clear, but generally, linking is not per se infringement, usually because no copying happens.
Wikipedia and you likely have no contract. If you don't have to click "I agree" to access the data, its likely there is no contract. Therefore this is a pure IP law question. The ONLY IP law issue that I see is copyright. The DATA is not subject to copyright. Only the expression of that data. So copying the html and selling that IS potential copyright infringement. Copying the data in some other format and using that is not. Finally, even if you do copy the full html (i.e. full expression), this MAY be licensed by their terms of use (as you suggested they have licensed some content). That is a more particularized legal question that I can't answer here.
No. The images are copyrighted, and you are using them in a way that would leave you with virtually no argument for fair use. The factors for fair use are set out in 17 USC 107, and they indicate that the courts would reject your use: The purpose and character of the use, including whether it is of a commercial nature or for nonprofit educational purposes: There's no indication that your use would be for nonprofit or educational purposes. The nature of the copyrighted work: Works of fiction and art are highly creative works at the heart of the policy for copyright protection. The amount of the portion used in relation to the copyrighted work as a whole: You are apparently copying entire images, though I suppose you could argue that each image is just one small portion of a larger book or website. The effect of the use upon the potential market for or value of the copyrighted work: You are trying to create a board game, putting yourselves basically in direct competition with the makers of D&amp;D. I generally prefer a pretty liberal interpretation of what constitutes fair use, but this just has virtually nothing that would make me comfortable arguing in your favor.
Of course it's legal. Hyperlinking to an unaffiliated website in no way &quot;determine[s] the means and processing of data.&quot; The person who makes these determinations is the person running the website. If I link to Microsoft's website, that doesn't give me any control over how Microsoft processes data on the website.
If you are using just the names, there is no issue - you can't copyright a fact. If you are using actual images (you appear to say you are not, but you also asked "Am I allowed to include images of Google Maps) - then the answer is still yes within your usage case - provided you attribute them to Google. If you look at this link it specifies that you are OK to use this in Reports and Presntations, Books which are not guidebooks and which have less then 5000 copies and presentations. If you are using them online, you need to use the imbedded versions (ie you can't just screenshot them - you need to link to them). If you are still unsure, you can contact streetview-academic@google.com to request specific permission.
No This is not a copyright issue as you are not making a copy (save for a transient one in your cache which is allowed). You are allowed to record it for personal time-shifting as that is fair use/dealing. The broadcaster either owns the copyright (unlikely) or has a contract with the copyright holder that allows them to broadcast it. Assuming the broadcaster chooses or is not permitted to subsequently stream it, if you miss it, you miss it. Your contract with the broadcaster is over. Their obligation was to make the broadcast available to you, yours was to pay for it - nobody is obliged to watch it. You can, of course, seek the content from any other legal sources, complying with their terms including payment if necessary.
If users were to copy dictionary definitions, for instance Oxford or Cambridge) and make the word lists public, is it a copyright infringement? If the dictionary entries are protected by copyright then your user has infringed that copyright by posting the dictionary entries. Am I responsible for this activity? No. But you may be responsible for removing it if you get a request. Can dictionary owners charge me against copyright issue? If you follow the procedures outlines in the DMCA you can be protected from liability.
Unfortunately, the "but everyone does that" (BEDT) argument doesn't hold water as evidenced by prosecutions of looters. Would uploading this video be a copyright infringement? It would be hard to answer this part of the question without knowing where and from whom the clips had come from. If the clips came from a company like ESPN or a YouTuber that doesn't give you permission to be able to use their clips then yes this might be a copyright infringement. If you use video/clips that are labeled as creative commons then nt it wouldn't be an infringement. YouTube has a feature for this. Would my actions be fair use? First, we'll need to understand what fair-use is. Fair use is the ability to use copyright material under certain circumstances without permission. To best determine if using copyright-protected material in your work you should weigh it against the four factors of fair use. The purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes; The nature of the copyrighted work; The amount and substantiality of the portion used in relation to the copyrighted work as a whole; The effect of the use upon the potential market for or value of the copyrighted work.
