Abstract
Methods and apparatus, including computer program products, implement techniques for repurposing digital information. One or more repurposing constraints are associated with information in an electronic document. A digital signature is associated with the repurposable information and the repurposing constraints. The repurposable information can be repurposed and represented as signed information subject to the repurposing constraints.
