Licensing your data will specify how, or not, your data can be re-used. It can specify terms and conditions, and access rights for re-use. Some licenses are non-exclusive, meaning that data bearing one license might also hold other licenses. This can happen when there is one license for commercial use, and another for non-commercial use. If your data has commercialization possibilities, please check with Versitech or HKU's Technology Transfer Office for their suggested licensing. Specific funders may have specific requirements on intellectual property rights, and thus determine which license you must use. Specific repositories where you deposit data may require a certain license only.
