Policy
Preservation and persistent identifiers
How records are kept available for the long term.
Identifiers
Every record receives a DOI. Proceedings volumes and books also carry ISBNs. Identifiers are never reassigned and always resolve, even for withdrawn records.
Storage
Files are checksummed on upload and replicated to a second location. Records in open formats (PDF/A, CSV, plain text) are preferred. A preservation plan describes how content would be transferred to another repository should AEX CONTINUUM ever cease operation.
