The following tables describe how various metadata fields schemas are populated (via DSpace Crosswalks) in the METS file for an AIP.

DIM

...

(DSpace Intermediate Metadata) Schema

DIM Schema is essentially a way of representing DSpace internal metadata structure, which is essentially very similar to a Qualified Dublin Core. However, DSpace's metadata allows for custom elements, qualifiers or schemas to be created. These custom fields/schemas may or may not be able to be translated into normal Qualified Dublin Core.

In the METS structure, DIM metadata always appears within a dmdSec inside an <mdWrap MDTYPE="OTHER" OTHERMDTYPE="DIM"> element.

DIM Descriptive Elements for Item objects

As all DSpace Items already have user-assigned DIM (essentially Qualified Dublin Core) metadata fields, those fields are just exported into the DIM Schema within the METS file.

DIM Descriptive Elements for Collection objects

For Collections, the following fields are translated to the DIM schema:

For Communities, the following fields are translated to the DIM schema:

DIM Descriptive Elements for Site objects

For the Site Object, the following fields are translated to the DIM schema:

AIP Technical Metadata Schema (AIP-TECHMD)

The AIP Technical Metadata Schema is a way to translate technical metadata about a DSpace object, into a DIM Schema. It is kept separate from DIM as it is considered technical metadata rather than descriptive metadata.

In the METS structure, AIP-TECHMD metadata always appears within a sourceMD inside an <mdWrap MDTYPE="OTHER" OTHERMDTYPE="AIP-TECHMD"> element. For example:

  <amdSec ID="amd_2191"> 
      ...
      <sourceMD ID="sourceMD_2198">
         <mdWrap MDTYPE="OTHER" OTHERMDTYPE="AIP-TECHMD">
         ...
         </mdWrap>
      </sourceMD>
      ...
  </amdSec>
