Preservation Policy

The University of Texas Digital Repository is committed to responsible and sustainable management of submitted works.

  1. Digital preservation is an evolving field; therefore, UT Digital Repository’s long-term access strategies are shaped by the Open Archival Information System (OAIS) reference model (ISO 14721:2012) and informed by relevant international standards and emerging best practices. 
  1. Prudent efforts will be employed to preserve work in any digital format submitted to UT Digital Repository, however submission in a recommended file format is strongly encouraged in order to facilitate long-term preservation.  Please see Recommended File Formats for a list of preferred formats

    For files in formats other than those listed in Recommended File Formats, a derivative file in a more stable format might be created.  In such cases, resources permitting, the original file as well as the derivative will be preserved, along with associated descriptive and administrative metadata for both files.

  1. UT Digital Repository will provide long-term access to submitted works, as well as associated descriptive and administrative metadata, by employing a strategy combining the following:

    •     Secure backup
    •     Storage media refreshment
    •     File format migration (including possible migration to standard formats during submission)

    At this time, UT Digital Repository is committed to preserving the bitstream (the binary form of the data).  Further practical measures to preserve as much functionality (“look and feel”) of the original as possible will be employed as resources permit.    

  1. All works submitted to UT Digital Repository will be assigned a persistent URL.
  1. This policy and related preservation activities will be reviewed regularly to ensure practices remain current as technology and institutional practices evolve.
