You are most welcome to contribute to the project.  You can start by download the source code, compile and use the library.  If you make any changes, you can create a ticket in the Issue Tracker with your suggested changes and we can look at making you a developer.

Hi Saripalli,

Sorry for the delay in responding.  You can download the free Ocean Template Designer from the product release page at  Using archetypes downloaded from the openEHR Clinical Knowledge Manager,, you can create a template using the Template Designer.  You can export an Operational Template XML file using the Template Designer, which can then be used in conjunction with the openEHR.NET library by deserialising an OperationalTemplate instance using the OperationalTemplateXmlReader. A Composition constructed from the openEHR.NET RM classes can be validated using OperationalTemplate.Definition.ValidValue.  You can walk the OperationalTemplate Definition tree and call DefaultValue on each CObject if you want assistance in constructing the RM class prototypes.

I am sorry I haven't had a chance to provide any documentation or sample code, but you can look at, it is a working windows application developed using openEHR.NET, Temaplates and openEHR archetypes..

Is it possible for you to give us an overview on how to read and template and navigate and render it .  I am planning to use OpenEHR to render the templates in HTML5

Two ways I suggest you can try, use the Operational Template XML output from the Ocean Template Designer and apply an XSL Transform to render as required. If you have created the transform using the Open.NET API then you should use the OperationalTemplateXmlWriter to generate the XML instead.

The second approach is to read the Operational Template XML using OperationalTemplateXmlReader and traverse the resulting Archetype Object Model instance to render as required. 

Good luck, let us know when you have it going.
