# Revision History

##### Document Revision History

The OSCAL revision history requires one FedRAMP extension to meet FedRAMP’s revision history requirements.

The revision history’s author information is derived from FedRAMP’s `party-uuid` flag, which points to a metadata `party` UUID value. The published field accepts the NIST OSCAL data type format. For details, see date-time-with-timezone on the NIST website.

<div class="callout">
<i><b>Note:</b></i> FedRAMP OSCAL requires only the publication date, not the time. You may replace the time portion with all zeros.
FedRAMP tools should present only the date in a user-friendly format.
</div>

The `remarks` field is a Markup multiline format, which enables formatting of text and requires special handling.
