Other questions about data ownership have to be discussed, for example around the topics of derivative products and data persistence. Data portals might ease the pain of granting access to data streams but if new intellectual property (IP) is added to a raw dataset, the derived works could be considered to be a new, independent product, with its own associated rights and permissions. Here an appropriate language in a data use/exchange agreement is critical between the original data generator and vendor.
Establish a ‘chain of custody’ to transparently link the owner of the data to the user of the data. Once this ‘chain of custody’ is established it will be important for data generators to understand how long their data might reside within a derivative data product. An give the option to the farmer to add or subtract users of their data.
