remove rdf:JSON if it doesn't meet the requirements of an RDF datatype

[pfps]

If rdf:JSON does not meet the requirements of an RDF datatype then it should be removed from RDF concepts.

[IS4Code]

Thesis please?

[pfps]

There are requirements for RDF datatypes in RDF Concepts. The description of rdf:JSON does not meet these requirements.

[domel]

Which fragment of the RDF Concepts spec does define these requirements?

[pfps]

https://w3c.github.io/rdf-concepts/spec/#section-Datatypes

[domel]

I can't find a relevant quote in this fragment that would support your opinion.

For example, "A JSON Array is mapped to a list by performing this mapping on each array value." is inadequate because it does not say how the list is constructed.

A large part of specifications is taking what might appear to be obvious and writing it down so that there can be no misunderstandings.

The value space is has ordered maps. What is the order? How is it supposed to be "ignored"?

"A JSON String is mapped to a string." What is the string?

And more.

For example, "A JSON Array is mapped to a list by performing this mapping on each array value." is inadequate because it does not say how the list is constructed.

You may quibble with the wording, but the spec does address how to map a JSON Array to a list:

A JSON Array is mapped to a list by performing this mapping on each array value.

Rather than saying that it does nothing, you might instead suggest how this definition can be improved. Perhaps by being even more exploit by saying "... by creating a new list which each value of that list is created by performing this mapping on that value and placing it at the same index within the target list." IMO, the meaning is already pretty clear.

A large part of specifications is taking what might appear to be obvious and writing it down so that there can be no misunderstandings.

The value space is has ordered maps. What is the order? How is it supposed to be "ignored"?

From the definition of map equality, order doesn't matter, thus it can be ignored.

A JSON Object is mapped to a map by transforming each object member into a map entry with the key taken from the member name and value taken by performing this mapping to the member value. Map entries are treated as being unordered.

Also, IMO, the last sentence doesn't add any value as order never comes into any operation on this component.

"A JSON String is mapped to a string." What is the string?

More wording could be taken from, say, Turtle on the specific mapping:

A JSON string is used with escape sequences unescaped to form the RDF string of the lexical form.

Please make (or respond to) suggestions for improving the wording rather than trow bricks at the entire effort.
