DIGITAL PRESERVATION POLICY DEVELOPMENT

Preconditioning Policy

“…describe the limits of change that can be introduced to digital content from the time it is brought within the control of Archives or the Library to its acceptance into the preservation system.”

PRECONDITIONING POLICY RULES

• The action will not affect the intellectual content of the file

• All changes must be reversible

• All changes must have “a system-based provenance note that clearly describes the change that has been made to the file”

Sample Provenance Note

<section id="event"> <record> <key id="eventIdentifierType">Indigo</key> <key id="eventIdentifierValue">Indigo_1</key> <key id="eventType">CREATION</key> <key id="eventDescription">Provenance Note from Indigo</key> <key id="eventDateTime">Wed Mar 18 12:47:24 NZDT 2015</key> <key id="eventOutcome1">SUCCESS</key> <key id="eventOutcomeDetail1">002_File extension was added: The file was submitted by the donor without a file extension. On the recommendation of the Preservation Analyst, a .wpd extension was added to this filename by the Digital Archivist as it has been identified as WordPerfect for Windows, version 5.1. </key></record>
