hasdai is a pilot infrastructure for preservation of scientific annotation. It was developed by Data Futures with partners Bodleian Libraries and CERN after RDA Plenary nº11, and supports redelivery of existing research data from legacy technologies, as well as new projects, with long-term support using Core Trust Seal repositories. Annotation trials from additional research domains discussed at RDA Plenary nº12 are now being developed, and a Preservation of Scientific Annotation Working Group (PSA) is being established under the RDA Preservation Tools, Techniques and Policies IG.
