Identifier Relationships
Beyond composition (one identifier containing another), PubID models relationships between separate identifiers. These capture how documents relate to each other across their lifecycle.
Overview
Relationships are expressed in parenthetical annotations on the identifier. A single document may have multiple relationships:
ANSI N42.18-2004 (Reaffirmation of ANSI N42.18-1980; Redesignation of ANSI N13.10-1974)Relationship Types
Revision Of
A new edition that replaces a previous version of the same document.
| Example | Meaning |
|---|---|
IEEE Std 802.3-2018 (Revision of IEEE Std 802.3-2015) | 2018 edition revises the 2015 edition |
Reaffirmation Of
A document confirmed as current without technical change.
| Example | Meaning |
|---|---|
ANSI N42.18-2004 (Reaffirmation of ANSI N42.18-1980) | 2004 edition reaffirms the 1980 edition |
ANSI C57.12.22-1993 (R1998) | 1993 edition reaffirmed in 1998 |
Supersedes
A document that replaces a previous, possibly differently-numbered document.
| Example | Meaning |
|---|---|
IEEE Std X-2020 (Supersedes IEEE Std Y-2010) | New document replaces the old one entirely |
Incorporates
A document that includes the content of another standard.
| Example | Meaning |
|---|---|
IEEE Std 1234-2020 (Incorporates IEEE Std 5678-2015) | Standard includes content from another |
Adoption Of
A publisher's version of another organization's standard.
| Example | Meaning |
|---|---|
IEEE Std C37.60-2005 (Adoption of IEC 62271-111) | IEEE adopts the IEC standard |
Redesignation Of
A document renumbered under a new identifier.
| Example | Meaning |
|---|---|
ANSI N42.18-2004 (Redesignation of ANSI N13.10-1974) | Same content, new number |
Previously Designated As
The inverse of redesignation — the old name for a renamed document.
| Example | Meaning |
|---|---|
IEEE Std X-2020 (Previously designated as IEEE Std Y-2010) | Formerly known by a different number |
Multiple Relationships
A single identifier can carry multiple relationships, separated by semicolons:
ANSI N42.18-2004 (Reaffirmation of ANSI N42.18-1980; Redesignation of ANSI N13.10-1974)This document is simultaneously a reaffirmation of one standard and a redesignation of another.
Publisher Support
| Publisher | Revision | Reaffirmation | Supersedes | Incorporates | Adoption | Redesignation |
|---|---|---|---|---|---|---|
| IEEE/ANSI | Yes | Yes | Yes | Yes | Yes | Yes |
| ISO | Via edition tracking | — | — | — | — | — |
| IEC | Via edition tracking | — | — | — | — | — |
IEEE maintains the richest set of explicit relationships, tracked as structured data in the PubID model.
