Identifiers

ABI — AkademBase Identifier

The persistent identifier for every object in the ecosystem (work, author, source, topic).

What ABI is

ABI (AkademBase Identifier) is a permanent, stable identifier that names every object consistently across the ecosystem. Links don't change — the ABI is preserved even if the object moves.

Structure

An ABI looks like this: it consists of a namespace, a collection and an id.

ABI

ABI:AkademIndex/openalex/2025.article.000007

Format: ABI:Namespace/collection/id

Resolution

Every ABI resolves through the API. The relevant endpoint is called depending on the object type:

HTTP

GET /v1/works/{abi}
GET /v1/authors/{abi}

Soon

Future: DOI mapping

DOI mapping is added as an overlay: ABI remains the primary identifier, with DOI as a complement (shown where available).
