FAIR Guiding Principle F4: 

(meta)data are registered or indexed in a searchable resource

Interpretation of F4

Principle F4 states that digital resources must be registered or indexed in a searchable resource (e.g., a search engine). The searchable resource provides the infrastructure by which a metadata record (made accessible with a GUPRI, F1) can be discovered, using either the attributes in that metadata (F2) or via the identifier of the resource itself (F3) [21].

This interpretation of F4 is based on 'FAIR Principles: Interpretations and Implementation Considerations'. Jacobsen et al, Data Intelligence 2020; 2 (1-2): 10–29. doi: https://doi.org/10.1162/dint_r_00024
