Free tools for use with CDFPrototypes

[JDziurlaj]

This thread is to describe current efforts to allow users to use free or open source software to use the prototypes developed so far.

• All Schematron rulesets require a schema-aware processor
• xml2json requires schema-aware processor, XSLT3
• json2xml requires XSLT3

AltovaXML Community Edition Version 2013 rel. 2 is the last known free, schema aware processor. However, it only supports XSLT2. Saxon supports XSLT3, but the open source version does not support the required fn:json-to-xml and fn:xml-to-json functions.

AltovaXML does not support extension methods in either Java or .NET.
It may be possible to write a pure XSLT polyfill for xml-to-json, then use AltovaXML to transform.
