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.

...

aip.disseminate.dmd = MODS, DIM

The MODS metadata is included within your AIP primarily as to support interoperability. It provides a way for other systems to interact with or ingest the AIP ( without needing to understand the DIM Schema). You may choose to disable MODS if you wish, however this may decrease the likelihood that you'd be able to easily ingest your AIPs into a non-DSpace system (unless that non-DSpace system is able to understand the DIM schema). When restoring/ingesting AIPs, DSpace will always first attempt to restore DIM descriptive metadata. Only if no DIM metadata is found, will the MODS metadata be used during a restore.

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.

In the METS structure, PREMIS metadata always appears within a techMD inside an <mdWrap MDTYPE="PREMIS"> element. PREMIS metadata is always wrapped withn a <premis:premis> element. For example:

  <amdSec ID="amd_2209"> 
      ...
      <techMD ID="techMD_2210">
         <mdWrap MDTYPE="PREMIS">
            <premis:premis>
              ...
            </premis:premis>
         </mdWrap>
      </techMD>
      ...
  </amdSec>

Each Bitstream (file) has its own amdSec within a METS manifest. So, there will be a separate PREMIS techMD for each Bitstream within a single Item.

By default, PREMIS metadata is always included in AIPs. It is controlled by the following configuration in your dspace.cfg:

aip.disseminate.techMD = PREMIS, DSPACE-ROLES

PREMIS Metadata for Bitstream

The following Bitstream information is translated into PREMIS for each DSpace Bitstream (file):
