All of Hagley’s publicly available digital content is stored and accessed via Hagley’s Islandora platform hosted on Amazon’s AWS service and backed up via daily snapshots in Amazon. The back-up is audited and tested annually to ensure restoration in the event of failure. In addition, hi-resolution files and metadata - as they were immediately prior to ingest into Islandora – are managed locally on a high volume external storage device (as of 2016, we are using DROBO devices). All of this content is being sent annually to Amazon’s Glacier service to protect from a local failure. These two copies will serve as a backup in the very unlikely event that Amazon AWS experiences a catastrophic failure.
Hagley has rights to duplicate and disseminate these items online as the creators donated their collections, along with rights.Hagley has deep experience and a strong track record in the area of rights and reproductions and in the nine years of the Hagley Digital Archive. We have never received a request to remove an item due to contested rights claims.
Hagley uses Zeutschel Omniscan OS 12000 equipment. Nearly all of the items we scan are flat and within the dimensional limits of our equipment (58 cm x 83 cm). Oversized items are scanned in parts and stitched into a single image using Photoshop. Our digitization standards are as follows: black and white items at 400 dpi, grayscale, 8-bit; color items at 400 dpi, RGB, 24-bit; all saved as TIFF, no compression for archival copies; with compressed JPEGs deployed in our Digital Archives. Video digitization is done using an OpenCube DCP/SD 2.11.0. Preservation video follow the Libray of Congress standards for video (JP2/MXF preservation files.) Metadata follows METS/MODS standard and is managed along with the preservation and access copies of digital objects.
