*The container metadata file (ContainerMetadata.xml) has two fields whose values will be used to populate the PREMIS rights entity in the SIP (in the METS <rightsMD> element), DateClosed and RetentionSchedule. Examples are:
 +
**<DateClosed>2012-08-17T16:13:31-08:00</DateClosed>
 +
**<RetentionSchedule>EV2.3.A</RetentionSchedule>
 +
*The DateClosed field will be used to populate the termOfRestriction startDate in the PREMIS rights entity
 +
*The DateClosed and RetentionSchedule fields will be used to calculate the termOfRestriction endDate in the PREMIS rights entity. For the examples provided above, Archivematica would calculate 5 years from the end of 2012-08-17 and then to the end of the calendar year, for a result of 2017-12-31.
 +
*The closure period would also be captured as a standardized free text entry in the rightsGrantedNote field of the PREMIS rights entity, for example: Closed until 2012-12-31.
 +
*Other PREMIS fields would be auto-populated for every VanDocs ingest as shown in the screenshot below.

==DIP upload==

 +
*Upon DIP upload to AtoM, the container will become a file-level description, with level of description populated by the structMap div label for the container ("file"). Each object in the DIP will become a child level with the level of description populated by the structMap div label for the object ("item").
 +
*Descriptive metadata in RAD will be populated by the appropriate dmdSec for each container and object (see container and document metadata mapping, above).

This page is no longer being maintained and may contain inaccurate information. Please see the Archivematica documentation for up-to-date information.

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

TRIM export contents[edit]

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)


VanDocs1g.png


Processing a TRIM export[edit]

Parsing contents to the SIP[edit]

  • 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[edit]

The contents of the transfer must be verified against the manifest.txt file during the "Verify transfer compliance" micro-service. Associated PREMIS event: manifest check. See below for details.

Verifying checksums[edit]

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

These checksums must be verified during the "Verify transfer checksums" micro-service. Associated PREMIS event: fixity check

The AIP METS file[edit]

dmdSecs[edit]

  • Each container will have one dmdSec consisting of Dublin Core metadata derived from the TRIM export metadata (ContainerMetadata.xml)
  • Each file will have one dmdSec consisting of Dublin Core metadata derived from the TRIM export metadata (eg DOC_2012_000100_Metadata.xml)

n/a Level of description: Item



amdSecs[edit]

  • Each container will have an amdSec consisting of:
    • A digiprovMD with an xlink reference to metadata/ContainerMetadata.xml


Sample amdSec for a container


  • Each file will have an amdSec consisting of:
    • A rightsMD populated with PREMIS rights (see Flagging closed AIPs, below)
    • 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[edit]

  • 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 in the logical structMap 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


StructMapg.png


Flagging closed AIPs[edit]

  • The container metadata file (ContainerMetadata.xml) has two fields whose values will be used to populate the PREMIS rights entity in the SIP (in the METS <rightsMD> element), DateClosed and RetentionSchedule. Examples are:
    • <DateClosed>2012-08-17T16:13:31-08:00</DateClosed>
    • <RetentionSchedule>EV2.3.A</RetentionSchedule>
  • The DateClosed field will be used to populate the termOfRestriction startDate in the PREMIS rights entity
  • The DateClosed and RetentionSchedule fields will be used to calculate the termOfRestriction endDate in the PREMIS rights entity. For the examples provided above, Archivematica would calculate 5 years from the end of 2012-08-17 and then to the end of the calendar year, for a result of 2017-12-31.
  • The closure period would also be captured as a standardized free text entry in the rightsGrantedNote field of the PREMIS rights entity, for example: Closed until 2012-12-31.
  • Other PREMIS fields would be auto-populated for every VanDocs ingest as shown in the screenshot below.

DIP upload[edit]

  • Upon DIP upload to AtoM, the container will become a file-level description, with level of description populated by the structMap div label for the container ("file"). Each object in the DIP will become a child level with the level of description populated by the structMap div label for the object ("item").
  • Descriptive metadata in RAD will be populated by the appropriate dmdSec for each container and object (see container and document metadata mapping, above).
