METS Export Profiles (SIP / AIP / DIP)

Overview

Heratio's per-record METS download supports three OAIS-standard profile shapes from the same exporter. The profile controls how much metadata and which file groups end up in the downloaded XML.

Profile Use case What it contains
SIP Submission Information Package - hand a record off to an external preservation system or partner archive Minimal Dublin Core, rights + source administrative metadata, original master file only
AIP Archival Information Package - the internal preservation master with full forensic trail Full Dublin Core, full PREMIS event chain, master plus preservation plus access files
DIP Dissemination Information Package - sanitised public download Full Dublin Core, rights only (PREMIS suppressed), access copies only

The PROFILE attribute on the root <mets> element changes per profile so downstream consumers (Archivematica, RODA, dArceo) can tell at a glance which package shape they received.

How to download a specific profile

  1. Open the archival description show page.
  2. In the right-hand action bar, choose METS export under the Linked Data heading.
  3. The default download is AIP. To grab SIP or DIP instead, append ?profile=sip or ?profile=dip to the download URL:
/informationobject/{slug}/export/mets             - AIP (default)
/informationobject/{slug}/export/mets?profile=sip - SIP
/informationobject/{slug}/export/mets?profile=dip - DIP

What each profile leaves out

SIP

  • Subjects, places, languages, creators - the SIP descriptive metadata stays deliberately minimal so downstream systems can re-derive their own descriptive layer.
  • PREMIS event history - submission packages predate the preservation chain.

AIP

  • Nothing. The AIP is the complete picture and should never be exposed publicly without a separate access decision.

DIP

  • The PREMIS event history (digiprovMD entries). Forensic data, staff agent identities, and migration trails are removed.
  • The sourceMD administrative section, for the same reason.
  • Master and preservation files - only access copies are referenced.

Use cases

  • Hand-off to Archivematica or RODA - SIP.
  • Internal preservation snapshot or archival backup - AIP.
  • Public data dump / open access download - DIP.
  • See docs/reference/mets-phase-4-profiles-sparql.md for the developer reference (API signature, PROFILE URIs, file layout).
  • The PROV-O JSON export (/informationobject/{slug}/export/provo) is the JSON-LD companion to the PREMIS chain inside the AIP.
  • The SPARQL endpoint at /admin/sparql lets you query the PROV-O graph for a single record - see the developer reference for query examples.
