17. Storage AIP access and delivery

18. Storage Metadata iRODS can store metadata for data objects 18 AVUs defined for dataObj bac186cd-4d11-48ac-bb1d-4ab2cd7593cc.tar: attribute: uuid value: bac186cd-4d11-48ac-bb1d-4ab2cd7593cc units: ---- attribute: producerID value: DE-MUS-019910 units: ---- attribute: submissionID value: DE-MUS-019910-201505131006 units: ---- attribute: checksum value: sha2:E4dMTd7/J4z9qg36CSjSzdXXIa4ltgAak+MKfSuPKww= units: ---- attribute: lastFixityCheck value: 2015-05-13T08:06:16Z units: ---- attribute: type value: AIP units:

19. Storage Abstraction AIPs managed by iRODS need to be accessed through front end Retrieval: – AIP-uuid in iRODS metadata – reference in RELS-EXT of AACO 19

21. Wrap up

22. Conclusion New data model – added support for different user views on a preservation item New Islandora-module – (Basic) iRODS access 22

23. Future development Trigger preservation workflow actions from Islandora – migration – fixity check – metadata amendment Reporting – Total Objects – occupied storage Managing iRODS (resources) 23
