Creative Commons
If you publish an article or book, or make a video or similar, that you want to make publicly available, you can mark it with a so-called Creative Commons license. This is a way of tailoring your copyright based on the extent to which you wish to permit others to share and use your work.
CC licenses often allow a larger degree of use and sharing, but it depends on the individual license. Therefore, if you want to use a work with a CC license, you must check the license of the work in question. This is Creative Commons own list of the individual licenses.
You can try to tailor your Creative Commons license based on this Swedish Internet guide to Creative Commons.
