Workflow

  • Metadata ingest: Metadata will be created outside of Archivematica prior to ingest and added to the metadata folder of the transfer. See Metadata, below.
  • Metadata validation: Archivematica should include a micro-service to validate metadata on ingest, using something like xmllint. Sample validation command: xmllint --schema ddi:instance:3_1 metadata/CCRI-CDN-Census1911V20110628.xml.
  • Normalization:Some datasets may require manual normalization: see https://projects.artefactual.com/issues/1499.


Metadata

METS and DDI/FGDC

  • DDI is Data Documentation Initiative, a metadata specification for the social and behavioral sciences; see http://www.ddialliance.org/.
  • FGDC is Federal Geographic Data Committee Metadata Standard [FGDC-STD-001-1998]; see http://www.fgdc.gov/metadata/csdgm/
  • DDI and FGDC are considered descriptive metadata (mdSec) in METS. From http://www.loc.gov/standards/mets/METSOverview.v2.html: "Valid values for the MDTYPE element [in mdSec] include...DDI (Data Documentation Initiative), FGDC (Federal Geographic Data Committee Metadata Standard [FGDC-STD-001-1998]."
    • In the Archivematica METS file, a DDI or FGDC file could be referenced from the mdSec using mdRef, for example as follows: <mdRef LABEL="CCRI-CDN-Census1911V20110628.xml-73b93b28-be1b-433f-861e-03bc321dfe7e" xlink:href="metadata/CCRI-CDN-Census1911V20110628.xml" MDTYPE="DDI" LOCTYPE="OTHER" OTHERLOCTYPE="SYSTEM"/>.
