Harvard Library collections include image sequences, a format used primarily in motion picture film scanning, that will be preserved in the Library’s preservation and access repository - the Digital Repository Service (DRS). As a first step towards providing support for this material in the DRS, the Library contracted AVPreserve in late 2015 to assist with the analysis. The goals of the analysis were:

  • Recommended image sequence formats to accept and prefer for the DRS
  • Recommended technical metadata schema(s) to use for image sequence file formats
  • DRS content models for these objects
  • Recommendations for enhancing Harvard Library’s FITS tool to better support these objects

The driving principles of this work were to:

  • Provide interoperability with the existing metadata schemas and workflows of the DRS
  • Provide sufficient metadata for long-term preservation of image sequence objects
  • Adhere to existing standards where possible
  • Propose simpler models over more complex ones where possible

Specifically the analysis was conducted in three areas: formats, metadata and tools. The work is ongoing. The deliverables from this analysis are included on this page.
