The CMS Run Registry: Data Certification and Publication System tool

The Run Registry of the Compact Muon Solenoid (CMS) experiment at the LHC is the central tool to keep track of the results from the data quality monitoring scrutiny carried out by the collaboration. Recently it has been upgraded for the upcoming Run3 of LHC to a new web application which will replace the current version successfully used during Run1 and Run2. It consists of a Javascript web application frontend which connects to an PostgreSQL database in the backend. The data quality information is recorded for each Lumi Section, which corresponds approximately to 23 seconds of data taking at CMS. The new platform incorporates user feedback on shortcoming and support for new use cases like Machine Learning and interfaces. In this presentation we describe the architecture and the the commissioning of the service over the past months and the rest of long shutdown 2.
