To provide tailored access to different groups of materials, we will need first to have them categorized based on their security status. We can do this using metadata collected in the description stage and in the preparation phase for ingest. If collected properly, our metadata should allow us to clearly map any content that should be considered “sensitive.” Archival data may be sensitive because of legal, security, or personal considerations. Marking material as “sensitive” may imply limited use (e.g., on-site only, closed, or conditional access).
