The Digital Preservation Network working groups have provided an overview of the types of metadata to consider while preparing deposits for DPN. Several areas are addressed:
- DPN-specific metadata, especially DPN-specific metadata, DPN’s BagIt specification, Tag Directories and Bag Structure.
- DuraCloud-specific metadata, while they do not restrict metadata they "indicate that local policies should be used to define metadata approaches". Each snapshot contains four DuraCloud-created files: checksums (md5, sha265), a content properties file, and a collection-snapshot file
- Core descriptive metadata records. The DPN Preservation Metadata Standards Working Group examined minimal metadata records from a variety of member institutions to find common metadata schemas. This resulted in a “core record,” or the "minimum level of information needed in order to understand digital assets at a later date," shown in a clear chart.
- Significant properties of content. "In order for digital files to be usable and accessible in the long-term, it is important to recognize the importance of significant properties and to ensure that the properties of your digital materials are being documented in some form." They list content types, with examples of common significant properties.
