This document includes a set of use cases and requirements, compiled by the Permissions & Obligations Expression (POE) working group, that motivate the expression of statements about digital content usage. All use cases provide realistic examples describing how people and organisations may (or want to be able to) specify statements about digital content usage. The requirements derived from these use cases will be used to guide the development of the POE WG recommendation deliverables for the Information Model, Vocabulary and Encodings.
