International Metrology Resource Registry


Developed in a collaboration between ODI and ITL and hosted by BIPM, the IMRR is a web-based service that allows national metrology institutes and their designated institutes to publish information about their data holdings, data services, standards documents, metrology-related software, websites, and about their organizations themselves.  The goal of the IMRR is two-fold:  expose the services and capabilities of the national metrology institutes to a broad community of researchers, industrial partners, and government agencies, and allow the NMIs to better coordinate their research and development efforts through increased visibility of each other’s activities.  The IMRR officially opened for contributions from the NMIs worldwide in January 2018.
