While I was uploading some original works, I got an idea about the original tag: make it a copyright tag.
Let's start with the basics. We already know that the term "copyright" is an imperfect term and that it's used to mark certain tags, generally tags of shows (gundam), major brands or concepts (vocaloid) or otherwise strongly recognizable terms (os).
I think that every image should ideally have a copyright tag. If you think about it, the copyright tag basically tells you "this thing (or these things) is where this image is coming from". That's the function of the copyright tag for fanart images. But that's also the function of the original tag: it tells you "this image isn't 'from' anything, it's an original image by the artist." I think it has the same value, and should be highlighted in the same way.
The main advantage of doing this is that you can immediately look for the copyright tag on any image. Not only is this nice in general when browsing, it will make images with no copyright tag at all by definition incompletely tagged. Perhaps we could even enhance the mouseover prompt (which I currently find hard to read at times, due to the many tags that are only sorted alphabetically) so display the artist and copyright tags first, or an "artist missing/copyright missing" if either or both are missing.
What do you think, good idea? Terrible?
