Improvements/Avalon

From Archivematica
Jump to navigation Jump to search

This page will document potential areas of improvement in Archivematica that will allow for better workflows with Avalon.

Project Thesis

Artefactual and Avalon will seek to create:

  • support for activities such as file characterization and preservation metadata extraction:
    • digitized and born-digital AV materials.
  • Integration with Archivematica or its components into Avalon ingestion workflows to provide:
    • preservation metadata
    • better packaging for long-term digital preservation activities

Use Cases

In scope

Two clear use-cases based on previous discussion (up to 8 March 2018), for which we can focus on and keep scope narrow. These are:

  • Avalon first
    • Process in Avalon and then send the package to Archivematica to generate an AIP

Questions

- Do we ignore the Fedora metadata entirely? - Do we transfer Fedora metadata as a digital object, but perform no special conversion mapping - Out-of-scope: Mapping/cross-walk to try and see Fedora metadata mapped into Archivematica

  • AM first
    • Collection of assets described in a batch manifest and they are processed and then picked up by Avalon

Two useful phrasings, that could be considered nuances on these, that came from the same meeting:

  • As an user of Avalon send the output of a project to a repository and have institutional digital preservation policies applied to that collectionffor long-term preservation
  • As a preservation specialist, in a catastrophic scenario, be able to round-trip from AM back into an instance of Avalon**
    • NB Recognised that there is no hard-requirement to round-trip back into Avalon from Archivematica, though it was noted that it would be possible to learn quite a lot.

Out of scope

Versioning This is a very broad summary, but because of the potential for work to continue being completed on a 'unit' in Avalon, data will become out of date, and there may be a wish to see that updated in Archivematica. This is one example of where data might need updating or to be re-versioned. Others:

  • AIP Update following updated in Avalon
  • Data supplied as an asset to Avalon/Archivematica, e.g. VTT Subtitle Information, (addition of other languages/corrections, etc.)
  • Other cases

What do we need?

- Northwest to work with Sarah to discuss use-cases - Do we need more sample files/batches of data? - Understand the current transfer issue being experienced with the initial setup - In progress.

Questions

METS

  • Is it required that the metadata in the batch ingest manifest is represented in the AIP METS file (in dmdSecs for example?)
  • Will users have a need to populate the batch ingest manifest with metadata entered into Archivematica?
    • Descriptive metadata?
    • Rights metadata?
  • When Avalon is being used to disseminate different quality files, which file(s) should be stored in the AIP?
    • How should mulitple versions be modeled in the METS?
  • Should the structure of files be modeled in the METS when structure XML files are included?
    • Or is describing the presence and use of structure files sufficient?
  • How should the presence of caption files be noted in the METS?

Exploration of Archivematica

  • Progress and first impressions
  • Ingest progress
  • Exploration of the AIP generated from Avalon Batch Packages
  • Immediate observations:
    • Workflow questions
    • Perceived or real gaps
    • Questions Artefactual can answer about what Archivematica is doing/should be doing
  • Relationship between Archivematica and Avalon, e.g position in workflow, pre-Avalon? post-Avalon? Something else?
