In early April 2011 the Party Infrastructure Project team will complete the migration of our data format from EAC 2004 to Encoded Archival Context - Corporate Bodies, Persons and Families (EAC-CPF). Once the migration is complete we will no longer support EAC 2004 (always a beta format) via SRU and OAI as previously advised in the SRU server documentation and the Party Infrastructure Description document. We are also working on mappings from RIF-CS 1.2 to EAC-CPF and will make these publicly available upon completion. Further information about the data migration and EAC-CPF will be provided in the near future.
