Info

The integrity features in the 1996 Preserving Digital Information report that were adopted for us in OAIS include:

  • Content: preserve “intellectual substance” of content as defined by significant properties 

  • Fixity: identifiable as a “whole and singular work” and any changes are recorded

  • Reference: uniquely identify and specifically refer to a digital object in relation to other digital objects across time 

  • Provenance: traceable to its origin, i.e., its point of creation, or, at minimum, from the point of deposit

  • Context: preserve technical dependencies, linkages with other objects, dissemination means and restrictions, and social environment (policies and norms)

The 2012 revision of the OAIS Reference Model added Access Rights to the list of integrity features, but otherwise retained the original set that was captured in the 1996 report.

Check with your organization about what descriptive, administrative, technical, rights, and preservation metadata for your digital content. There are both automated and manual methods of extracting and creating metadata. Metadata for digital content may be produced in different parts of an organization and some of that metadata may be duplicative. A tool can also create or extract the same metadata as another because of their similar purposes. The COPTR website is a good place to look for and learn about metadata tools.

Question for your team/organization: What are your DP services provider’s metadata requirements for the digital content they will be working with you to preserve? Does the transfer / Ingest tool create some of the technical and preservation metadata? TDL members contact TDL for more information and assistance.
