Digital format standards

There are lots of different kinds of digital format standards out there and it can be confusing to know which one to choose. We recommend digital format standards that follow these principles:

• Quality: A good format is lossless (retains all the information captured) and creates an accurate version that is flexible for future re-use.
• Interoperable: A good format can be used by different software and hardware platforms and migrated to different carriers over time.
• Widely supported: A good format follows a widely supported open or industry standard.
• Self-contained: A good format supports a unique identifier and the ability to embed metadata according to a standard metadata schema.

Continued usability in different environments and contexts is central to good practice, and all standards where possible should support this. We have identified some standards that we consider meet this test.
