EtherCIS (Ethereal Clinical Information System) is an Open Source platform compatible with the openEHR standard. It is design to allow simple interactions with clients using RESTful API and persist clinical data in a separate DB engine. Clinical data are exchanged using different formats:
FLAT JSON: which is a flatten representation of access path along with the corresponding field value
Canonical XML: representing an openEHR composition in standard XML
For more details on data representation in openEHR see this page
