AO2

AO2 is a generic alphanumeric designation used by many organizations to label items, versions, or categories. There is no universal definition for the term; its meaning is determined by the context, schema, or system in which it appears. As such, AO2 functions as a label rather than a concept with a single, inherent meaning.

In information technology and data management, AO2 often appears as a suffix or component within file names, databases, or configuration identifiers to indicate a revision, variant, or subcomponent. The exact interpretation—such as what constitutes a revision or which component is being labeled—depends on the project's metadata and naming conventions.

In libraries, archives, or cataloging systems, AO2 can serve as a collection or shelfmark code, aiding item retrieval and tracking. The designation is defined by the catalog's schema and may encode information about provenance, sequence, or physical location. Users should refer to the specific cataloging guide to understand its scope and meaning in that context.

Other domains, including manufacturing, logistics, or research projects, may employ AO2 as a workflow step label, location code, or subtype designation. Because the label lacks inherent meaning, interpretation relies on local documentation.

If you can specify the domain or dataset for AO2, a more precise definition can be provided.
