EtherCIS is a DB centric openEHR compliant SOA platform. It exposes a RESTful API handling OpenEhr entities under three formats (Flat json, AQLPath json and XML). The motivation of EtherCIS has been to provide an open, scalable yet secure clinical data repository that can be queried using different languages (AQL and SQL). SQL querying is performed using standard tools, as recent progresses in DB developments now allow combinations of relational and schema-less data structures. We will discuss our experiences (and failures) with previous persistence approaches, pros and cons of the current one and future perspectives in line with major DB engines developments.
Implementation of an openEHR repository using a Graph Database (Samar El Helou)
Building openEHR repositories is challenging since it requires a thorough grasp and implementation of the openEHR Reference Model (RM) that has numerous classes in a tree-structure with deep hierarchy. Moreover, a mismatch between the database model and the RM can lead to high development time and cost. The graph model shares many semantic similarities with the definitions of the openEHR RM making it a potential fit for its representation and implementation. We will propose a method for implementing an openEHR repository by a graph database employing the labeled property graph model. We will also discuss some limitations and opportunities of persisting openEHR data with Neo4j.
