With many thanks to everyone who commented on the draft version, I'm happy to say that our Recommended Practice, RP-19-2020, Open Discovery Initiative: Promoting Transparency in Discovery, is now published and freely available for use by the information community.
Index-based discovery services are one of the main channels through which users discover and access content. NISO's Open Discovery Initiative provides technical recommendations for the exchange of data, in order to provide a way of assessing content providers' participation in discovery services and to ensure fair and unbiased indexing and linking. The updated Recommended Practice provides a more detailed treatment of Abstracting and Indexing (A&I) content products, and supports better metadata sharing (including information about open access material) and record display, as well as improved tracking of usage statistics and authentication mechanisms. It also includes advice on systems, training, and communication for libraries that configure and upgrade their discovery systems.A big thank you to the ODI Steering Committee members for their work on this!
