Christian,

Can you give an example of how to convert JSON data to atomic XQuery items (sepecifically strings, numbers and booleans)?  Is it as simple as removing the curly brackets to bound an object?

    Hi Maurice,

    Depending on the chosen format, different outputs will be generated by
    json:parse. Traditionally, it is true that only XML was generated by
    this function, but in newer versions (and in alignment with the XQuery
    3.1 specs and the fn:parse-json function), it is also possible now to
    convert JSON data to atomic XQuery items (maps, arrays, strings,
    numbers and booleans) [1,2]. The resulting representation will be more
    memory-efficient, and access to XQuery maps is blazing fast, but it
    won’t be possible to store this representation to a database.

    Hope this helps, greetings,
    Christian

Aside from XQuery and BaseX converting JSON, because JSON is not just objects, I think there could be a problem with the concept of converting JSON to maps, also. For example, these JSON documents aren’t map-like:

1. true
2. ["a", "a", "a", "x"]
