This page documents ingest of TRIM exports based on requirements for VanDocs ingest at City of Vancouver Archives.


TRIM export contents

A TRIM export consists of

  • 1 or more containers
  • A manifest of the transfer (manifest.txt)
  • XML schema documentation for all xml files in the transfer (container, location and document xml metadata)
  • Location metadata (Location.xml)
  • Container metadata (ContainerMetadata.xml)
  • Document metadata (eg DOC_2012_000100_Metadata.xml)
  • Documents (eg DOC_2012_000100.docx)

Processing a TRIM export

Parsing contents to the SIP

  • Each container becomes a single transfer OR each transfer is broken into one SIP per container
  • manifest.txt is copied to metadata/submissionDocumentation/
  • Location.xml is copied to metadata/
  • All schema documentation is copied to metadata/
  • The relevant ContainerMetadata.xml is copied to metadata/
  • The relevant document metadata files are copied to metadata/
  • All documents are copied to objects/


A SIP generated from a TRIM export


Verifying manifest

The contents of the transfer must be verified against the manifest.txt file during the "Verify transfer compliance" micro-service.

Verifying checksums

Each document metadata file contains an md5 checksum for the document:

These checksums must be verified during the "Verify transfer checksums" micro-service.


The AIP METS file

dmdSecs

  • Each container will have one dmdSec consisting of Dublin Core metadata derived from the TRIM export metadata
  • Each file will have one dmdSec consisting of Dublin Core metadata derived from the TRIM export metadata

<TitleFreeTextPart> <dc.title> <unittitle> Title proper Remove structured part from TitleFreeTextPart
n/a n/a <c> Level attribute Level of description Level of description will be obtained from METS StructMap div TYPE

<Notes> n/a <note> General note
<RecordNumber> <dc.identifier> <unitid> n/a AtoM adds an identifier field to archival descriptions

amdSecs

  • Each container will have an amdSec consisting of:
    • A rightsMD with an xpointer reference to the AccessControl element in metadata/ContainerMetadata.xml
    • A digiprovMD with an xlink reference to metadata/ContainerMetadata.xml
    • A digiprovMD with an xlink reference to metadata/Location.xml


Sample amdSec for a container


  • Each file will have an amdSec consisting of:
    • A rightsMD with an xpointer reference to the AccessControl element in the relevant document metadata xml file
    • A digiprovMD with an xlink reference to the the relevant document metadata xml file
    • A techMD and digiprovMDs generated by Archivematica during processing


Sample amdSec for a file


fileSec and structMaps

  • Each METS file will have two structMaps, the Archivematica default structMap and a logical structMap for hierarchically arranging the container into a file and its child items
  • The container and file div TYPE elements will map to the RAD Level of description field in AtoM
  • The structMap contains the links between containers and files and their relevant dmdSecs
  • The structMap also contains the link between the container and its amdSec
  • The files are linked to their amdSecs in the fileSec
