  • Translating an EAD that describes an archival collection as a whole into well-formed Hydra/Fedora objects
    • Creating the set object that represents the entire collection
    • Creating intermediate set objects that represent the EAD hierarchy
    • Creating "item" objects that represent nodes in the hierarchy that describe individual objects
  • Translating item level information into well-formed (per Hydra) Fedora objects
    • Required datastreams and child objects
    • EAD to MODS mapping
  • Address the born digital materials
    • Recognizing what in the EAD describes "Born digital" content
    • Enriching the digital objects with file-level information

EAD only goes down to the single "Born digital" series description, with no details expressed at lower levels. A rationalized directory structure and FTK output are intended to support a direct translation into Hypatia objects for both unprocessed and processed views without an intermediary EAD.
