<div dir="ltr">Hi everyone,<div><br></div><div>I'd like to introduce my open-source JS library, Jsonix (<a href="https://github.com/highsource/jsonix">https://github.com/highsource/jsonix</a>) which - in my opinion suits very well for OWS needs.</div>
<div><br></div><div>Jsonix stands for "JSON interfaces for XML" and allows converting between JSON and XML in certain schema with no pain.</div><div>Here's a small code example to demonstrate what it looks like:</div>

<span class="">});</span></pre></div><div><br></div><div>You can try it online in JSFiddle: <a href="http://jsfiddle.net/lexi/LP3DC/">http://jsfiddle.net/lexi/LP3DC/</a></div><div><br></div><div>Jsonix is schema-driven. You can basically take an XML Schema and compile it into JSON-XML mappings.</div>
<div>Jsonix will then be able to unmarshal XML into JSON which is very easy to process in JavaScript programs.</div><div>You can also marshal JSON into XML so you're getting the full XML<->JSON rountrip for free.</div>
<div><br></div><div>Java developers out there will defintely recognize similarities to JAXB. Jsonix is basically a JAXB analog for JavaScript.</div><div><br></div><div>I wrote Jsonix with OGC Schemas in mind.</div><div>Here's a WMS demo: <a href="https://github.com/highsource/jsonix/tree/master/demos/wms">https://github.com/highsource/jsonix/tree/master/demos/wms</a></div>
<div>Here's a sample WPS project: <a href="https://github.com/highsource/jsonix/tree/master/nodejs/tests/wps">https://github.com/highsource/jsonix/tree/master/nodejs/tests/wps</a></div><div><br></div><div>So if you need a reliable, schema-driven, strongly-typed and structured XML-JSON conversion for you target OGC spec, you can take Jsonix, compile your schema and save all those gory XML-to-JSON-and-back details, just concentrate on your payload in a neat predictable JSON form.</div>
<div><br></div><div>Jsonix works in most browsers (browser protability is ~ OpenLayers).</div><div>Works with node.js. Works with RequireJS. No conflicts with OpenLayers.</div><div>Open-source (3-clause BSD), no strings attached.</div>
<div>Heavily tested.</div><div><br></div><div>I'd be very glad if you consider using Jsonix for OWS. I'd be happy to provide support and help as much as I can.</div><div><br></div><div>Best wishes,</div><div>Alexey Valikov</div>
