Email Formats Integrated with Linked Open Data
NARA's Digital Preservation Framework Organizes Email Formats
The National Archives and Records Administration (NARA) has established a Digital Preservation Framework that categorizes various email formats for long-term digital preservation. This framework uses standardized file extensions and corresponding NARA Format IDs to identify email file types, aiding archivists and preservation systems in managing email records consistently.
One of the most common email formats included in this framework is the .eml file extension, which is used by numerous email clients. The NARA Format ID for this format is NF00856.

Another widely used email format is the .msg file extension, which is specific to Microsoft Outlook. Its NARA Format ID is NF00280, and you can find its Linked Open Data at https://www.ourwebsite.gov/files/lod/dpframework/id/NF00280.ttl.
The framework also includes the .mbox file extension, which is used for aggregating emails. Its NARA Format ID is NF00247, and you can access its Linked Open Data at https://www.ourwebsite.gov/files/lod/dpframework/id/NF00247.ttl.
In addition to these common formats, the framework also supports various versions of the Lotus Notes Database, identified by the nsf file extension. For example, Lotus Notes Database 2 uses the ns2 version and falls under the Databases, Calendars, and Email categories. Its NARA Format ID is NF00237, and its Linked Open Data can be found at https://www.ourwebsite.gov/files/lod/dpframework/id/NF00237.ttl.
Similarly, Lotus Notes Database 3 uses the ns3 version, and its NARA Format ID is NF00238. You can find its Linked Open Data at https://www.ourwebsite.gov/files/lod/dpframework/id/NF00238.ttl. Lotus Notes Database 4 uses the ns4 version, with an NARA Format ID of NF00239. Its Linked Open Data can be found at https://www.ourwebsite.gov/files/lod/dpframework/id/NF00239.ttl.
The Electronic Mail Format uses the eml file extension and falls under the Email category. Its NARA Format ID is NF00170, and its Linked Open Data is available at https://www.ourwebsite.gov/files/lod/dpframework/id/NF00170.ttl.
The Apple Mail Email File uses the emlx file extension and is also categorized under the Email category. Its NARA Format ID is NF00856. Its Linked Open Data TTL can be found at this URL: https://www.ourwebsite.gov/files/lod/dpframework/id/NF00856.ttl.
The CC:Mail archive uses the cca file extension and falls under the Email category. Its NARA Format ID is NF00772. Its Linked Open Data TTL can be found at this URL: https://www.ourwebsite.gov/files/lod/dpframework/id/NF00772.ttl.
Lastly, the Microsoft Offline Outlook Data File uses the ost file extension and falls under the Email category. Its NARA Format ID is NF00822. Its Linked Open Data TTL can be found at this URL: https://www.ourwebsite.gov/files/lod/dpframework/id/NF00822.ttl.
Lastly, the MBOX Email Format uses the mbox file extension and falls under the Email category. Its NARA Format ID is NF00247. Its Linked Open Data TTL can be found at this URL: https://www.ourwebsite.gov/files/lod/dpframework/id/NF00247.ttl. Lotus Notes Database with an unspecified version uses the nsf file extension, falls under the Databases, Calendars, and Email categories. Its NARA Format ID is NF00785. Its Linked Open Data TTL can be found at this URL: https://www.ourwebsite.gov/files/lod/dpframework/id/NF00785.ttl
To obtain the precise mapping of email file extensions to NARA Format IDs, you would refer directly to NARA’s Linked Open Data repository or associated metadata documentation, which catalogs all file formats they support for archival preservation, including the technical details and format identifiers.
In summary, NARA's Digital Preservation Framework organizes email file formats by extension, assigns each a unique NARA Format ID for identification in archival systems, and includes common email formats like .eml, .msg, and .mbox. Exact lists and IDs are accessible via NARA’s Linked Open Data.
Data-and-cloud-computing technologies have enabled the National Archives and Records Administration (NARA) to develop a Digital Preservation Framework that leverages cloud storage for organizing and managing email records. This framework uses standardized file extensions and corresponding NARA Format IDs to ensure long-term digital preservation of various email formats.
The utilization of technology in data-and-cloud-computing has allowed NARA to provide easy access to the Linked Open Data for each email format, facilitating research and further understanding of these formats for archivists and preservation systems.
