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.
