The OAI-rights effort, initiated in collaboration with project RoMEO, have announced the release of their guidelines for conveying rights expressions about metadata in the OAI-PMH framework. Andy Powell was a member of the team that contributed to this effort. The guidelines specify a mechanism for including rights expressions that pertain to the contents of the <metadata> parts of records in OAI-PMH responses and the design has been guided by the need for simple and clear semantics that will allow service-providers to make harvesting and use decisions based on these rights expressions.
