User Story

As a FedRAMP OSCAL content generator, I need clear and consistent guidance on when to uses specialized FedRAMP OSCAL extensions versus when to use generalized core OSCAL props and values, and a clear understanding of the constraints around all extensions.

Goals

• Review each FedRAMP extension and determine which of the following treatments apply:
• Keep extension as-is (do nothing)
• Deprecate the extension (no longer needed)
• Transition to core OSCAL approach; deprecate FedRAMP extension
• Propose new OSCAL allowed value(s); deprecate FedRAMP extension

By reviewing each extension and determining the required approach, this will result in clear requirements that when implemented will:

• Eliminate namespace collisions
• Ensure consistency across all artifacts (e.g., extensions registry, values, validations rules, OSCAL guides, and OSCAL templates)

Acceptance Criteria

• Comprehensive listing of all FedRAMP extensions including
  • Model(s) the extension applies to
  • Name
  • Description
  • Approach (keep, deprecate, transition, transition w/ proposed change
  • Constraints
  • Where changes are required (registry, values file, OSCAL guides, OSCAL templates, other)

Other information

This issue is focused on conducting the analysis so that the requirements are clarified. Subsequent issue(s) will implement the necessary updates.
