DSpace exports

Main Page > Development > Development documentation > DSpace exports

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 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:

• calamy.zip
• ITEM@123456789-7.zip
• ITEM@123456789-8.zip

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)

Item-level METS file

• <metsHdr>
• <dmdSec> (contains MODS metadata for item)
• <dmdSec> (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)
