- Bitstreams and Bundles are second-class archival objects; they are recorded in the context of an Item.
- BitstreamFormats are not even second-class; they are described implicitly within Item technical metadata, and reconstructed from that during restoration
- EPeople are only defined in Site AIP, but may be referenced from Community or Collection AIPs
- Groups may be defined in Site AIP, Community AIP or Collection AIP. Where they are defined depends on whether the Group relates specifically to a single Community or Collection, or is just a general site-wide group.
What is NOT in AIPs
DSpace Site configurations (\[dspace\]/config/ directory) or customizations (themes, stylesheets, etc) are not described in AIPsWiki Markup - DSpace Database model (or customizations therein) is not described in AIPs
- Any objects which are not currently in the "In Archive" state are not described in AIPs. This means that in-progress, unfinished submissions are never included in AIPs.

mets/dmdSec
element(s)- By default, two
dmdSec
elements are included for all AIPs:- object's descriptive metadata crosswalked to MODS (specified by
mets/dmdSec/mdWrap@MDTYPE="MODS"
). See #MODS Schema section below for more information. - object's descriptive metadata in DSpace native DIM intermediate format, to serve as a complete and precise record for restoration or ingestion into another DSpace. Specified by

. See #DIM (DSpace Intermediate Metadata) Schema section below for more information.
- object's descriptive metadata crosswalked to MODS (specified by
- For Collection AIPs, additional
dmdSec
elements may exist which describe the Item Template for that Collection. Since an Item template is not an actual Item (i.e. it only includes metadata), it is stored within the Collection AIP. The Item Template'sdmdSec
elements will be referenced by adiv @TYPE="DSpace ITEM Template"

@TYPE

attribute which names the crosswalk that produced (or interprets) that metadata, e.g.DIM

mets/amdSec
element(s)- One or more
amdSec
elements are include for all AIPs. The firstamdSec
element contains administrative metadata (technical, source, rights, and provenance) for the entire archival object. AdditionalamdSec
elements may exist to describe parts of the archival object (e.g. Bitstreams or Bundles in an Item).techMD
elements. By default, two types oftechMD
elements may be included:PREMIS
metadata about an object may be included here (currently only specified for Bitstreams (files)). Specified bymdWrap@MDTYPE="PREMIS"

rightsMD
elements. By default, there are four possible types ofrightsMD

For the Site Object, the following fields are translated to the DIM schema:
Metadata Field | Value | |
---|---|---|
<ac:structured-macro ac:name="unmigrated-wiki-markup" ac:schema-version="1" ac:macro-id="0359be53-c8c9-4e14-b0cf-3180431cb817"><ac:plain-text-body><![CDATA[ | dc.identifier.uri dc.identifier.uri | Handle of Site (format: |
dc.title | Name of Site (from dspace.cfg 'dspace.name' config) |
MODS Schema
...
By default, all DSpace descriptive metadata (DIM) is also translated into the [MODS Schema|http://www.loc.gov/standards/mods/] by utilizing DSpace's {{MODSDisseminationCrosswalk
}}. DSpace's DIM to MODS crosswalk is defined within your {{\[dspace
\]/config/crosswalks/mods.properties
}} configuration file. This file allows you to customize the MODS that is included within your AIPs.
For more information on the MODS Schema, see http://www.loc.gov/standards/mods/mods-schemas.html
In the METS structure, MODS metadata always appears within a dmdSec
inside an <mdWrap MDTYPE="MODS">
element. For example:
...
Metadata Field | Value |
---|---|
dc.identifier.uri | Handle of Community |
dc.relation.isPartOf | Handle of Parent Community (as a URN) |
AIP Technical Metadata for Site
.relation.isPartOf | Handle of Parent Community (as a URN) |
AIP Technical Metadata for Site
Metadata Field | Value |
---|---|
Metadata Field | Value |
dc.identifier.uri | Site Handle (format: |
PREMIS Schema
At this point in time, the PREMIS Schema is only used to represent technical metadata about DSpace Bitstreams (i.e. Files). The PREMIS metadata is generated by DSpace's PREMISCrosswalk
. Only the PREMIS Object Entity Schema is used.

If a Group name includes a Community or Collection _Internal ID_ (e.g. "COLLECTION_45_SUBMIT"), and that Community or Collection no longer exists, then the Group will be renamed to a more generic, random name of the format: "GROUP\_\[random-hex-key\]\_\[object-type\]\_\[group-type\]" (e.g. "GROUP_123eb3a_COLLECTION_ADMIN"). The reasoning is that we were unable to translate an _Internal ID_ into an _External ID_ (i.e. Handle). If we are unable to do that translation, re-importing or restoring a group with an _old_ internal ID could cause conflicts or instability in your DSpace system. In order to avoid such conflicts, these groups are renamed using a random, unique key. |
