Data License
The legal terms that govern how a dataset may be used, shared, and redistributed.
Definition
A data license is the set of legal terms that govern how a dataset may be used, copied, modified, shared, or sold. It can permit broad reuse, restrict use to research or non-commercial purposes, or impose attribution and share-alike requirements. For AI development, license terms determine whether data can legally enter a training corpus, making them an important factor in data sourcing and compliance.
