Expanding Digital Designs and Vector Graphics with Linked Open Data
NARA's Digital Design and Vector Graphics Preservation Plan
The National Archives and Records Administration (NARA) has outlined a comprehensive preservation plan for Digital Design and Vector Graphics records. This plan emphasises the use of open, well-documented, and stable formats for long-term preservation and format transformations.
Adobe Illustrator, a popular vector graphics editor, falls under this category. NARA has assigned the following Format IDs to various versions of Adobe Illustrator:
- Adobe Illustrator 1.0/1.1: NF00668
- Adobe Illustrator 3.0/3.2: NF00669
- Adobe Illustrator 11.0: NF00824
- Adobe Illustrator 12.0: NF00825
- Adobe Illustrator 13.0: NF00826
- Adobe Illustrator 14.0: NF00827
These RDF Turtle files can be found on NARA's website and can be opened in any text editor.
Other software falling under the Digital Design and Vector Graphics category includes Autodesk's 3DS Max, which is assigned the Format ID NF00100.
The preservation plan encompasses several key processes:
- Normalization or transformation: This involves converting original or at-risk formats into preservation-friendly formats. For example, converting proprietary vector format files into SVG or PDF/A.
- Validation and quality control checks: After transformation, it's crucial to confirm the integrity and fidelity of the digital object.
- Documentation and metadata capture: This step involves documenting transformation processes and technical characteristics of the resultant files to aid future accessibility and authenticity.
While NARA does not explicitly detail its internal tools and processes for format transformations, general good practice in this domain often involves the use of specialized digital preservation tools and workflows, adherence to FAIR data principles, and continuous monitoring and reviewing of guidelines and adherence to international standards for format sustainability and preservation.
For instance, command line tools like ImageMagick for images or open source vector graphics editors like Inkscape can be used for batch transforming and validating files.
NARA makes its Linked Open Data available in Resource Description Framework Terse RDF Triple Language (RDF Turtle) .ttl files. The Linked Open Data TTL files for various software and formats can be found on NARA's website. For example:
- Adobe Illustrator 1.0/1.1: https://www.our website.gov/files/lod/dpframework/id/NF00668.ttl
- Adobe Illustrator 3.0/3.2: https://www.our website.gov/files/lod/dpframework/id/NF00669.ttl
- Adobe Illustrator 11.0: https://www.our website.gov/files/lod/dpframework/id/NF00824.ttl
- Adobe Illustrator 12.0: https://www.our website.gov/files/lod/dpframework/id/NF00825.ttl
- Adobe Illustrator 13.0: https://www.our website.gov/files/lod/dpframework/id/NF00826.ttl
- Adobe Illustrator 14.0: https://www.our website.gov/files/lod/dpframework/id/NF00827.ttl
- 3DS Max: https://www.our website.gov/files/lod/dpframework/id/NF00100.ttl
The Digital Design and Vector Graphics Preservation Plan can be used as test criteria for tools and processes used in format transformations. However, for specific NARA tools or software names, direct consultation of NARA's internal archives preservation documentation or technical guidance may be required.

The Digital Design and Vector Graphics Preservation Plan by NARA seeks to leverage technology and data-and-cloud computing for long-term preservation of digital records, with a focus on tools like Adobe Illustrator and Autodesk's 3DS Max. General practice often involves using specialized digital preservation tools, like Inkscape or ImageMagick, for format transformations, adhering to FAIR data principles, and following international standards for format sustainability and preservation.
