What is "jsoniq"

JSONiq is a query and functional programming language that is designed to declaratively query and transform collections of hierarchical and heterogeneous data in format of JSON, XML, as well as unstructured, textual data.

JSONiq is an open specification published under the Creative Commons Attribution-ShareAlike 3.0 license. It is based on the XQuery language, with which it shares the same core expressions and operations on atomic types. JSONiq comes in two syntactical flavors, which both support JSON and XML natively.

1. The JSONiq syntax (a superset of JSON) extended with XML support through a compatible subset of XQuery.
2. The XQuery syntax (native XML support) extended with JSON support through a compatible subset (the JSONiq extension to XQuery) of the above JSONiq syntax.
