5. Archivematica – EPrints Integration Proposal Rationale
Continue to use EPrints for depositor/ingest and access normalization
No need to develop software to process and ingest Archivematica DIPs
EPrints is designed as an open access system
Use Archivematica for creating preservation copies AIPs
Include eprint identifiers to be able to find AIPs by eprint ID.
Archivematica is designed for preservation

7. Archivematica – EPrints Integration
eprint Moves to "Repository" or is Updated
eprint is prepared for digital preservation export
digital preservation export is ingested
preservation workflow creates AIP with new METS file
AIP is stored in Archival Storage

8. Digital Preservation Export Structure
repositoryid-eprintid-lastmoddate folder (for example library _ )
data
revisions
1.xml
2.xml
derivatives
Folder # on disk (<pos>)
filename
metadata
EP3.xml
DublinCore.txt

9. Digital Preservation Export Structure
Folder# (<pos>)
fileid-xxxxx
files
documentid-xxxxx
Documents
eprintid-xxxx
data
eprintid-XXXXXX
documents
documentid-XXXXX
fileid-XXXXX
folder#-on-disk (“<pos>”)
filename

10. Example

11. Example - Bagged

12. Transfer -> Ingest -> Archival Storage

13. Example -> AIP files
migrated files

14. New AIP Metadata METS file from SIP Transfer manifest METS file
Format identification Logs
New manifest

15. METS.xml

16. METS.xml

17. Challenges Exporting derivatives Efficiency Source location on disk
Metadata
How to reference programmatically?
Efficiency
Each modification to metadata would cause a new AIP to be archived – inefficient (duplication)
