Why Cite XFIDs

Permanence

XFIDs are content-based identifiers. They don't change when issuers move or remove documents. A citation using an XFID will resolve years after the original URL breaks.

Reproducibility

Two researchers citing the same framework with an XFID are provably referencing the same document. The identifier is computed from the content itself.

Version Tracking

If a document is revised, the new version gets a different XFID. Your citation locks to the exact version you analysed, even if the issuer updates it later.

Identifier Formats

Prefix	Entity	Example	Resolves at
`XF`	Document	`XF-A3B7K2M-9`	xframework.id/XFA3B7K2M9
`XP`	Person (analyst)	`XP3VN7Q7TV`	xframework.id/XP3VN7Q7TV
`XO`	Organization	`XO7KN83X7F`	xframework.id/XO7KN83X7F

The display format (with dashes: XF-A3B7K2M-9) and the compact format (without: XFA3B7K2M9) both resolve to the same page.
