Identifiers.org: Compact identifier resolution services
The Identifiers.org system is a central infrastructure for findable, accessible, interoperable and re-usable (FAIR) data. It provides a range of services to generate, resolve and validate persistent Compact Identifiers to promote the citability of individual data providers and integration with e-infrastructures.
The Identifiers.org registry contains hundreds of manually curated, high quality data collections, with each assigned a unique prefix. A combination of the prefix and a locally assigned database identifier (accession) forms a Compact Identifier, [prefix]:[accession]. The Identifiers.org resolver provides a stable resolution service for these Compact Identifiers, taking into consideration information such as the uptime and reliability of all available hosting resources. As Compact Identifiers and the resolving mechanisms of identifiers.org are generic, identifiers.org aligns well with other identifier systems and emerging requirements in the PID ecosystem.
