A common example of a useful identifier is the Digital Object Identifier (DOI) which is guaranteed by the DOI specification to be globally unique and persistent. DOIs provide an additional service, under principle A1, of being able to direct calls to the source data to the location of that data, even if the identified data moves. This ensures that identifiers are stable and valid beyond the project that generated them. In some circumstances, again with DOIs being an example, third-party persistent identifiers may also provide support for principle A2 (that metadata exists beyond the lifespan of the data) since these identifiers may still be responsive to Web calls, and be capable of providing metadata, even if the source resource is no longer active. For a discussion on identifiers see doi:10.1371/journal.pbio.2001414 and doi:10.5281/zenodo.3267434 .

Examples of metadata schemata can be found in FAIRsharing (https://fairsharing.org/standards/, doi:10.1038/s41587-019-0080-8, [McQuilton et al. Data Intell. DI-2019-0028, 2019]) and include for instance the Data Documentation Initiative (DDI) (https://doi.org/10.25504/FAIRsharing.1t5ws6), the HCLS Dataset Descriptors (https://fairsharing.org/FAIRsharing.s248mf), and many domain-specific “minimal information” models that have been invented.

An example of a technology that provides this link is FAIR Data Point (doi:10.1162/dint_a_00031), which is based on the Data Catalogue model (DCAT, https://www.w3.org/TR/vocab-dcat/) that provides not only unique identifiers for potentially multiple layers of metadata, but also provides a single, predictable, and searchable path through these layers of descriptors, down to the data object itself.

An example of a generic searchable resource that supports manual exploration is Google Dataset Search (https://toolbox.google.com/datasetsearch); however, this suffers from several of the problems mentioned above, in particular, that it indexes only certain types of metadata (schema.org) and the search cannot be automated under the Google Terms of Service, and therefore cannot be implemented within FAIR software.

The most common example of a compliant protocol is the HTTP protocol that underlies the majority of Web traffic. It has additional useful features, including the ability to request metadata in a preferred format, and/or to inquire as to the formats that are available. It is also widely supported by software and common programming languages.
