The Health Worker Registry serves as the central authority for maintaining the unique identities of health workers within a country. The Health Worker Registry is a database containing a minimum dataset of details of all health workers working in both the public and private sectors. With multiple and disparate sources of data on health workers, it is a complex task to pull together and maintain a master and canonical list of all health workers in a country. The health worker registry seeks to reduce the complexity of this task by: - Pulling the minimum dataset of health workforce information from the various source data systems. - Merging the source data systems into an authoritative registry of health workers according to a data governance policy. - Allowing queries of health worker information by client systems. https://guides.ohie.org/arch-spec/openhie-component-specifications-1/openhie-health-worker-registry-hwr
