Stanford Digital Repository
Archive Ingest & Handling Test (AIHT)
•Devise workflow for real world digital archive
•Incorporate the assessment process into ingestion
•Expand scope
•Automate
•Test utility & efficacy
•Record outcome in metadata
Then came along the AIHT project, which offered Stanford a substantial opportunity to:
-- design an ingestion workflow for a real world digital archive,
and
-- build on our previous format research and test our assessment methodology
 and
-- by incorporating the assessment process into the workflow, begin to consider how to generate and record pertinent metadata

The test’s subject – the 9/11 archive -- was a true “off the street” collection. Its heterogeneous nature required us to expand the scope of our assessment tool to include a number of format types.

Also, We recognized the need to automate the assessment tool. Automation, we presumed, would enable the methodology to scale sufficiently, would provide more realistic and trustworthy data for technical assessment, and therefore would help us maintain more control over workflow.

It would at the same time allow us to treat a heterogeneous collection as a more manageable set of object classes, enabling directed investment in preservation actions and the possibility of levels of service beyond bit preservation for select classes.
