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

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

Digital Preservation Export Structure repositoryid-eprintid-lastmoddate folder (for example library-981471-2016-11-05_05-20-53) data revisions 1.xml 2.xml derivatives Folder # on disk (<pos>) filename metadata EP3.xml DublinCore.txt

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

Example https://spectrum.library.concordia.ca/981471/

Example - Bagged

Transfer -> Ingest -> Archival Storage

Example -> AIP files migrated files

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

METS.xml

METS.xml

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)
