1. A computer-implemented method to license datasets, comprising:
under control of one or more computer systems configured with executable instructions:
providing a dataset with license tags attached to data items in data rows in the dataset, wherein each data row for the data items comprises a license tag and the license tags identify at least one license that is associated with the each data row for the data items, using a processor;generating a license file having a selected license tag, using the processor;generating a digital signature for the license file, wherein a hash value is calculated for the license file and the hash value is signed with a key;receiving the license file with a query;authenticating the license file by verifying the digital signature, using the processor;running the query against the dataset, using the processor; andfiltering out data items in data rows that do not have the selected license tag attached to produce a resultant set, using the processor.
