JSON lists are inherently ordered. The RDF-based metadata use mostly properties which does not preserve orderings. We could use RDFS list semantics, but those are (imo) mostly unneeded for the metadata as is.
Are (explicit) orderings necessary or can they be omitted?
For the JSON-String we decided for an explicit ordering to improve readability.
I'm not sure if this is necessary for RDF as well.
If it is easy to implement I would always suggest ordered metadata strings.
