Re: ANN: XML Schema to JSON Schema XQuery transform

The library module relies on XQuery 3.1 due to the use of maps.  

It can be used in MarkLogic with the version of ML that incorporates maps.

It can also be run in eXist-db.

To run this from the command line would be:

java -cp saxon9ee.jar net.sf.saxon.Query -q:load-xsd.xqy -s:schema2translate.xsd -o:translated-schema.json

NOTE:
 I have also added a flag for preserving namespace prefixes in the JSON Schema

Create an XQuery file called load-xsd.xqy with the following:

xquery version "3.1";
import module namespace xsd2json="http://easymetahub.com/ns/xsd2json" at "xsd2json.xqy";
declare namespace map = "http://www.w3.org/2005/xpath-functions/map";
declare namespace output = "http://www.w3.org/2010/xslt-xquery-serialization";
declare namespace xs="http://www.w3.org/2001/XMLSchema";
declare option output:method "json";
declare option output:indent "yes";
xsd2json:run(.//xs:schema, map { ‘keepNamespace’: Fn:true() } )
