COAR is leading a community project called Notify to "...develop a standard and interoperable approach that will link reviews and endorsements from different services with the research outputs housed in the distributed network of preprint servers, archives, and repositories."
Antleaf is developing and maintaining infrastructure to support the COAR Notify project. This includes the technical documentation for the specification as well as an experimental Linked data Notification "inbox" to support the development and testing of Notify implementations.
