Overview of how OpenCRVS uses best-practice technology standards

Because OpenCRVS is a core component of Digital Public Infrastructure, we are obsessed with conforming to good, existing standards.

CR Standards: Digital Convergence Initiative

OpenCRVS are a Standards Committee Member of the Digital Convergence Initiative, CRVS and SP-MIS interfaces. We helped author these standards and interoperate with social protection systems such as OpenSPP.

Centre for Digital Public Infrastructure - G2PConnect

OpenCRVS has contributed to and conforms to the G2PConnect standardised API using the DCI payloads above.


By using FHIR as a standard for our NoSQL datastore, Hearth and the OpenHIE standard interoperability layer OpenHIM, OpenCRVS seamlessly connects civil registration to health services and other systems. We can receive birth and death notifications from the hospital setting and expose registration events to any other technical system, such as National ID, via our FHIR standard API gateways.

FHIR was created by Health Level Seven International (HL7), a not-for-profit, ANSI-accredited, standards organization dedicated to providing a comprehensive framework and related standards for the exchange, integration, sharing and retrieval of electronic health information that supports clinical practice and the management, delivery and evaluation of health services.

We have extended FHIR's model to include custom codes and extensions that assist the Civil Registration context. To understand more about how and why we use FHIR, click here.


Systems can interoperate with OpenCRVS using FHIR or via Webhooks which follow WebSub process and standards. Our friends at MOSIP have demonstrated ease of integration with OpenCRVS using these methods.
