| Format Support Policy | top |
During the IDEALS pilot phase, formats are only categorized as known or unrecognized. Known items are those that we are currently analyzing further in terms of their support level. Unlisted formats are just unrecognized at this time. IDEALS accepts all formats (whether known or unrecognized).
Further details regarding file format recommendations will be made available during the pilot phase.
The current IDEALS Preservation Policy and Format Support is available in our "About IDEALS" section.
