Uniform Resource Identifier (URI): Generic Syntax

Generic syntax and resolution rules for URI references.

Identity and normative owner

Record: uri; record authority: Modeling. Normative owner of subject: IETF. Resource reference: https://www.rfc-editor.org/rfc/rfc3986 Registration is for discovery, not adoption, endorsement, or transfer of normative ownership.

Editions

  • RFC 3986: published RFC; updates/errata not reverified. Named edition for identification, not a claim that it is the newest edition.

Distributions and references

  • uri-documentation — documentation, text/html, en. Rights are assessed per distribution in the record. Unassessed rights do not imply permission to redistribute.

Verification scope

  • metadata-observed (2026-09-17): Primary-source page metadata observed; no distribution bytes, legal clearance, current-latest guarantee, or implementation conformance was verified.

Cautions

  • Separate identity from a current access location; preserve base URI for relative reference resolution.
