IDEALS uses registered Media Types (or MIME Types) to display information about file formats. MIME Types are automatically added to any file in a format recognized by the DSpace software.

See a complete list of MIME Type formats.


IDEALS uses a subset of the Dublin Core DCMI Type vocabulary with some modification to names for the dc.type field. These are:

  • Audio
  • Dataset / Spreadsheet
  • Image
  • Text
  • Video
  • Other


Each item that is deposited into IDEALS automatically receives a handle identifier, which can be thought of as the item's permanent home address.

It is also possible to link to other versions of the item through Digital Object Identifiers (DOIs), Archival Resource Keys (ARKs), or other standardized uniform resource identifiers (URIs). It is preferable that the additional identifier be clickable; that is, it should direct a user to a web page.
