Indiana University and WGBH recently presented their plans for the grant funded HydraDAM 2 project. Some interesting bullets from their presentation:
- HydraDAM 1 came from a need for WGBH to migrate off the vendor product Artesia which was heading in a new direction
- Indian University’s use case is to ingest 10 Terabytes per day for 4 years for a total of 6.6 Petabytes of master and use copy video files along with associated files for preservation into HydraDAM 2
- HydraDam 1 is too slow for ingest so ingest is handled externally
- HydraDam2 will use two different storage system models with Fedora 4 managing both online/nearline and offline tape copies
- Out of region copies are out of scope for the size of the collection going in, however, IU is a DPN member and plans to use that for high risk items. Currently they are in the process of setting policies and preservation levels associated with the content.
- Preservation services to be offered in HydraDam2 include:
- Storage and retrieval of files
- Scheduled fixity checks and file characterization on demand
- Auditing based on Fedora 4
- Media migration (from one storage solution to another storage solution)
- Format migration for risk of obsolescence
- There is a working version of Avalon using Fedora 4
This was a preliminary presentation. IU and WGBH will be giving a detailed presentation at the upcoming Open Repositories conference in June.
