Hi Henk, answers below...
1.) Is there an example or a proposal how to express an arc such as
"verifiedUsing" in JSON?
Since hashes are not an element they would typically be serialized as an
in-line array, for example:
{
...
"verifiedUsing": [
{
"type": "Hash",
"algorithm": "SHA512",
"hashValue": "A1B2C3..."
}
]
}
2.) Is there an example or a proposal how to express an arc, such as
"element", in JSON?
Good question, in the diagram I used the closed diamond shape which is
composition, however, now that both document and package can contain
elements, and they can also stand alone this should be a hollow diamond
indicating aggregation instead. Typically this would be serialized
something like this:
{
"elements": [
{
"type": "File",
"id": "some-id-a"
},
{
"type": "File",
"id": "some-id-b"
},
{
"type": "Package",
"id": "some-id-c",
"elements": [ "some-id-a", "some-id-b" ],
"rootElements": ["some-id-a"]
]
}
3.) Is there still the notion to use json-ld generics here, e.g. object
always include members, such as @comment and @id?
The logical model is indifferent to this. If we define a JSON-LD
serialization format for the specification then that would describe how the
fields map to JSON-LD constructs.
