Add properties required by FDA certification

[AlexanderYukhanov]

FDA requires (https://www.fda.gov/media/119933/download) suppliers to provide two additional attributes:
"

• The software level of support provided through monitoring and maintenance from the
  software component manufacturer (e.g., the software is actively maintained, no longer
  maintained, abandoned); and
• The software component’s end-of-support date.
  "

It would be beneficial to create taxonomy containing 4 additional attributes to meet this requirement:
fda:lifecycle:suport_level
fda:lifecycle:suport_level_comment
fda:lifecycle:end_of_support
fda:lifecycle:end_of_support_comment

The comment attributes are required to provide the justification for the provided attributes or the conducted effort description if those attributes were not detected

Is this not covered already?
see https://github.com/CycloneDX/cyclonedx-property-taxonomy/blob/main/cdx/lifecycle.md

[AlexanderYukhanov]

No, it's required to provide the level of support and justification both for level of support and the end of support date. Probably, we can extend cdx:lifecycle instead of declaring new fda:lifecycle like

cdx:lifecycle:suportLevel
cdx:lifecycle:suportLevelComment or cdx:lifecycle:suportLevelJustification
cdx:lifecycle: endOfSupportComment or cdx:lifecycle: endOfSupportJustification
?

Is there a definition of support level?

See also: Common Lifecycle Enumeration.

[AlexanderYukhanov]

No, there is no formal definition or additional guidance from the FDA on this. That's why including a justification field alongside the support level is beneficial. It allows vendors to apply their own criteria (for example, using the OSSF Scorecard's 'Maintained' score).

The Common Lifecycle Enumeration currently covers different use-cases and is not well-suited for describing the support levels of dependencies, especially OSS one.
