CMS Run Registry: Data Certification Bookkeeping and Publication System

The Run Registry of the CMS experiment at the LHC is the central tool for the tracking of the data quality monitoring and data certification workflows and the bookkeeping of the results. It consists of a Java web application frontend which connects to an Oracle database in the backend. The current production version 2 of the Run Registry application, was deployed in the beginning of the year 2010, before the LHC data taking started, and has since then undergone a number of full release cycles. In this note we describe the architecture and the experiences from the first year of datataking.
