calculateStatementFideId

Calculate a Fide ID for a Statement from its RDF triple components. Creates a statement Fide ID by hashing a canonical JSON representation of the subject-predicate-object triple. The resulting Fide ID always has type and source both set to Statement (0x00...).

calculateStatementFideId(subjectFideId, predicateFideId, objectFideId)

Parameters

subjectFideIdstring*
The Fide ID reference (format: did:fide:0x... or 0x...)
predicateFideIdstring*
The Fide ID reference (format: did:fide:0x... or 0x...)
objectFideIdstring*
The Fide ID reference (format: did:fide:0x... or 0x...)

Returns

const result = await calculateStatementFideId(

);

calculateFideId

Calculate a Fide ID for an entity from its type, source type, and raw identifier. Generates a unique identifier by creating a SHA-256 hash of the raw identifier, then constructing a Fide ID with type and source characters followed by the last 38 hex characters.

extractFideIdFingerprint

Extract the 38-character fingerprint from a Fide ID. The fingerprint comprises the last 38 hex characters after the type and source bytes, representing the last 19 bytes of the SHA-256 hash used to create the Fide ID.
