    abstract =  {In the Resource Public Key Infrastructure (RPKI), certificate authorities publish certificates, including end entity certificates, and CRLs to repositories on repository servers. Relying Parties (RP) retrieve the published information from the repository and MAY store it in a cache. This document specifies a delta protocol which provides relying parties with a mechanism to query a repository for changes, thus enabling the RP to keep its state in sync with the repository.},
