A unique key to link annotations (via 'evidence' attributes) to evidences. Describes the source of the data using a database cross-reference (or a 'ref' attribute when the source cannot be found in a public data source, such as PubMed, and is cited only within the UniProtKB entry). Describes the source of the evidence, when it is not assigned by UniProt, but imported from an external database.
