Persistent errors for user description. about ocfl-py HOT 4 CLOSED

Hi @johnguirgis :

"fixity": null is not valid in the inventory, you should omit the fixity key unless it has a JSON object value (reason for E056a)

The address value should be a URI, thus mailto:[email protected] and not [email protected] (reason for W009)

from ocfl-py.

@zimeon "fixity": null is valid JSON. If it is forbidden, the spec should make that clear.

from ocfl-py.

@pwinckles - I think it is clear in https://ocfl.io/1.0/spec/#fixity "The fixity block MUST contain keys corresponding to the controlled vocabulary given in the digest algorithms listed in the Digests section, or in a table given in an Extension." -- this implies a JSON object but if we want to add further clarification then that would be a spec issue

from ocfl-py.

Right, but I would interpret that to mean that if there is a fixity block then it must have those properties. The fact that fixity is null, to me, means that it does not have a fixity block. Serializing missing fields to null is typical, and often configurable, for some JSON serializers.
