Hi @AaronF ! :-) Thanks for your answer and explanation. That is exactly my question. Is metadata a copyright infringement? Your suggestion is an interesting and good solution. But I explicitly wanted to avoid that for several reasons. Regardless: I don't really understand about the hash though. Why should I only store a hash? Or do you think I should encode it to decode it again on request?
@AaronF Good Morning. Thank you for asking! You asked about the data handling of the scraped metadata. I store them in my database. I do not store the thumbnail on my server. Here I only use the link to the thumbnail which I have read from the metadata. I have edited my question in this regard.
To be honest, it always strikes me that the old copyright law (offline) has difficulties with the nature of the internet. What I mean to say is that it is difficult to counter copyright problems on the internet in the old copyright pattern. And by difficult, I mean technically difficult.
Thank you for the answer. And yes, my question could have been a bit more precise. Thanks also for the tip. Your answer seems plausible. Now I wonder what the legal situation is with the search engines. They scan the content of the page and store it in their database to present it on their site. That's what I had in mind. Is there consent through the robots.txt?
