Story (A paragraph or two describing what happens)

Derivative Objects are needed in DSpace to support dissemination of the original content in alternate formats. Cases where derivative formats are needed:

  • Text extraction for full text search
  • Thumbnail and preview image rendering for User interface
  • Alternative Image formats for preview tools (JPEG2000, @MIRE Image Zoom Tiles)
  • Alternative Audio / Video formats ( Ex: Flash and MPEG conversion for streaming purposes)

  1. This would be very useful.  We have also encountered a need to generate a directory of derivative assets for a single original bitstream.  It would be useful to have a mechanism to handle such a situation.  See FlexPaper Document Viewer for XMLUI

  2. Just a note that this may be related to Structure - Relationships between objects.

    If a "derivative" was actually a new type of object, or even just an alternative bitstream, there may be a better way of using an enhanced "relationship model" to describe how it relates back to the original.
