The SHARE initiative is developing a Notification Service to facilitate the preservation, access, and reuse of research outputs. They have been working on building the prototype Notification Service, which will provide structured reports of research release events like published articles and datasets to interested parties. The Center for Open Science is helping to harvest metadata from various sources to include in over 40,000 reports. The next steps include expanding the prototype and recruiting subscribers for a public beta release in early 2015 and full release in fall 2015. Challenges include encouraging the adoption of identifiers and dealing with scale, but benefits could include keeping researchers and institutions better informed of impacts.
