Validates perceptual hash instances with gUFO foundational constraints.
Focus nodes of this shape (cacontology-detection:PerceptualHash) can have the following properties:
| PROPERTY | DESCRIPTION | MIN | MAX | VALUE TYPE | OTHER CONSTRAINTS |
|---|---|---|---|---|---|
| cacontology-detection:hashAlgorithm | The specific algorithm used for perceptual hashing (e.g., 'pHash', 'aHash', 'dHash'). sh:message Hash algorithm must be from the allowed list |
1 | 1 | xsd:string |
sh:in
pHash, aHash, dHash, wHash, colorHash, blockHash
|
| cacontology-detection:perceptualHashValue | The perceptual hash value as a hexadecimal string. sh:message Perceptual hash value must be a hexadecimal string (8-128 characters) |
1 | 1 | xsd:string |
sh:pattern
^[0-9A-Fa-f]+$
sh:minLength
8
sh:maxLength
128
