The GEOMAGIA50 database stores 3798 archeomagnetic and paleomagnetic intensity determinations dated to the past 50,000 years. It also stores details of the measurement setup for each determination, which are used for ranking the data according to prescribed reliability criteria. The ranking system aims to alleviate the data reliability problem inherent in this kind of data. GEOMAGIA50 is based on two popular open source technologies. The MySQL database management system is used for storing the data, whereas the functionality and user interface are provided by server-side PHP scripts. This technical brief gives a detailed description of GEOMAGIA50 from a technical viewpoint.
