This page analyzes the structure of DSpace exports from an uncustomized (i.e. out of the box) DSpace installation.

Collection export

Used the following command (from DSpace user documentation) to export a two-item collection with the handle 123456789-6:

./dspace packager -d -a -t AIP -e <user name> -i 123456789-6 calamy.zip

This results in the export of three zipped packages: one for the collection and one for each of the items:

The extracted contents of each zipped file are shown in this screenshot:

Collection-level mets.xml file

The mets.xml file for the collection is structured as follows:

<mets ID="DSpace_COLLECTION_123456789-6" OBJID="hdl:123456789/6" TYPE="DSpace COLLECTION" PROFILE="http://www.dspace.org/schema/aip/mets_aip_1_0.xsd" xsi:schemaLocation="http://www.loc.gov/METS/ http://www.loc.gov/standards/mets/mets.xsd">
<metsHdr>
<dmdSec> (contains MODS metadata for collection-level description)
<dmdSec> (contains DSpace Intermediate Metadata (DIM) for collection-level description; all mapped to dc; some overlap with MODS metadata)
<amdSec> (contains information on DSpace users and groups associated with the collection)
<fileSec> (references the collection's logo, if there is one)
<structMap> (links the collection to its logo, if there is one, plus its two child items)
<structMap> (links the collection to the DSpace Community)

<metsHdr>
<dmdSec_1> (contains MODS metadata for item)
<dmdSec_2> (contains DIM metadata for item; all mapped to dc; some overlap with MODS metadata)
<amdSec> (contains rights metadata)
<amdSec> (contains rights metadata)
<amdSec> (contains PREMIS object metadata; rights metadata; DIM metadata for the item)
<amdSec> (contains rights metadata)
<amdSec> (contains PREMIS object metadata; rights metadata; DIM metadata for the licence)
<fileSec> (links the item to the license)
<structMap> (links the bitstream to the logical object)
<structMap> (links the item to the collection)

Requirements:

Map the elements of the DSpace AIPs to the Archivematica AIP
Structure the Archivematica mets.xml file to point to the relevant sections of the DSpace mets.xml files
Index the metadata in all the xml files

The digital objects get placed in the objects directory
The license.txt files get placed in the metadata/submissiondocumentation directory; the text is parsed to the <rights> container in the PREMIS metadata
The mets.xml files get placed in the metadata/submissionDocumentation directory

Archivematica mets file	DSpace mets file	Description/notes
<dmdSec>	n/a	DC metadata added during transfer/ingest; collection-level only
<dmdSec>	<dmdSec><mdWrap MDTYPE="MODS"> in collection-level mets.xml.	Use mdRef to point to the MODS metadata in the collection-level mets.xml file.
<dmdSec>	<dmdSec><mdWrap MDTYPE="MODS"> in item-level mets.xml	Use mdRef to point to MODS metadata in the mets.xml file. Repeat this <dmdSec> for each object in the AIP
<amdSec>	n/a	PREMIS metadata
<amdSec>	<amdSec><rightsMD>	rightsMDs are scattered all over the DSpace mets.xml files. I don't really know how to map them.
<fileSec>	n/a	Lists all the files in the AIP
<structMap
