Subject: Multiple fingerprints
As the spec stands, the result.fingerprints property is a JSON object, where the property values are computed fingerprints, and the property names are arbitrary values that identify the fingerprints.
Yekaterina, I understand that SCA needs multiple fingerprints so that it can recompute a fingerprint (perhaps if the algorithm changed?) and still keep the old value around. If that is your scenario, do you need each fingerprint to be associated with an identifier (the property name, in the current design), or would it be enough if result.fingerprints were an array?
Michael et al, is there any other scenario for multiple fingerprints than SCA’s? That is, is there any other reason to prefer an object over an array, or vice versa, for result.fingerprints? As the spec stands, it suggests that you could use the property names to identify different fingerprinting algorithms, and a result management system could choose among them to decide which sets of results were logically identical.
