UM DSpace exports 0.8

Archivematica can act as a "dark archive" for a DSpace repository - i.e. providing back-end preservation functionality while DSpace remains the user deposit and access system. Archivematica has been tested using exports from DSpace 1.7.x. Ingest has not been tested on exports from DSpace 1.8.x; however, there were no changes in the DSpace AIP export structure between 1.7.x and 1.8.x so it is anticipated that performance will be identical.

1. The transfer should be structured similar to the one in Archivematica's sample data at sampledata/SampleTransfers/DSpaceExport (figure 1). This is a standard DSpace export with one DSpace AIP for the collection-level description and one for each of the deposited objects.
   • The inclusion of the collection level export (eg aip_1314.zip) is not mandatory.
2. A typical zipped item folder will contain the uploaded object plus a license file, a METS file and possibly an OCR text file. Figure 2 shows an example:
   • bitstream_39691_txt = the OCR text file
   • bitstream_8272.pdf = the object deposited in DSpace
   • bitstream_8273 = the license file
   • mets.xml = the METS file for the item
3. To process, copy the transfer to Dspace1.7 in the left-hand panel of the file browser.
4. At the normalization step, choose "Preservation only"
5. The METS file for the AIP will show fileGrps for the different file types: original, submissionDocumentation (the mets.xml files), preservation, license and text/ocr. It also contains Xpointers to descriptive and rights metadata in the original mets.xml files exported from DSpace. (figure 3).
