Automated DIP generation
The tasks related to this phase of development are:
- change workflow so that the ‘upload DIP’ choice can be preconfigured.
- update AIP reingest workflow to allow uncompressed AIPs to be reingested.
- enhance the callback functionality in the Storage Service, to notify third party apps when a DIP is ready to be used.
These developments are necessary for research data management to meet use cases when research data is stored without the expectation that it will be re-used, but then subsequently a need for re-use arises and/or is approved by the creator of the data.
Workflow
- Access request is initiated through a staff alert to RDMonitor
- Request for DIP sent to Storage Service
- If DIP exists already in storage, return DIP
- If DIP does not exist, send wait response and initiate AIP re-ingest in Archivematica pipeline
- When DIP stored by Archivematica,return DIP message goes to RDMonitor
- If DIP creation/storage fails, failure message sent to RDMonitor.

Multiple checksum algorithms
Enhance PRONOM integration
Priorities for this phase are (in order of priority):
1. Provide report of non-identified files in a SIP or AIP, with access to the file identification tool output
2. Provide direct access to the PRONOM submission form from within Archivematica
Alternatives being discussed:
- Post tool output and optionally a sample file to the FPR, making that available publically and to PRONOM
3. Allow a user to manually assign pronom IDs to non-identified files; record manual selection in the AIP METS file
Automation tools documentation
Archivematica has features that enable quite a bit of automation and interaction from 3rd party applications, but most of that functionality is hidden and not well documented. The goal of this part of the work on improving Research data management workflows is about adding documentation, in written form and as screencasts/videos, aimed at developers, and other technical users of Archivematica. This will make it easier for developers working on other applications to integrate Archivematica into their organizations digital preservation workflows.
