Here we discuss the various intellectual property (IP) laws that can be relevant to the use of content for TDM activities. In some cases, exceptions to these laws apply, making it possible to re-use others’ content for TDM without needing specific permission from rights holders. In other cases, however, the law does not allow TDM without permission from rights holders. And even in cases where legal exceptions allow for TDM without explicit permission from rights holders, there may be scope for some aspects of a licence or contract to limit how you may use content for TDM. In these guidelines, we will discuss what you should be aware of when licensing content for use in TDM.
