AB: The Magnetics Information Consortium (MagIC) is commissioned to implement and maintain an online portal to a relational database populated by both rock and paleomagnetic data. The goal of MagIC is to archive all available measurements and derived properties from paleomagnetic studies of directions and intensities, and for rock magnetic experiments (hysteresis, remanence, susceptibility, anisotropy). MagIC is hosted under EarthRef.org at http://earthref.org/MAGIC/ and will soon implement two search nodes, one for paleomagnetism and one for rock magnetism. Currently the PMAG node is operational. Both nodes provide query building based on location, reference, methods applied, material type and geological age, as well as a visual map interface to browse and select locations. Users can also browse the database by data type or by data compilation to view all contributions associated with well known earlier collections like PINT, GMPDB or PSVRL. The query result set is displayed in a digestible tabular format allowing the user to descend from locations to sites, samples, specimens and measurements. At each stage, the result set can be saved and, where appropriate, can be visualized by plotting global location maps, equal area, XY, age, and depth plots, or typical Zijderveld, hysteresis, magnetization and remanence diagrams. User contributions to the MagIC database are critical to achieving a useful research tool. We have developed a standard data and metadata template (version 2.3) that can be used to format and upload all data at the time of publication in Earth Science journals. Software tools are provided to facilitate population of these templates within Microsoft Excel. These tools allow for the import/export of text files and provide advanced functionality to manage and edit the data, and to perform various internal checks to maintain data integrity and prepare for uploading. The MagIC Contribution Wizard at http://earthref.org/MAGIC/upload.htm executes the upload and takes only a few minutes to process tens of thousands of data records. The standardized MagIC template files are stored in the digital archives of EarthRef.org where they remain available for download by the public (in both text and Excel format). Finally, the contents of these template files are automatically parsed into the online relational database, making the data available for online searches in the paleomagnetic and rock magnetic search nodes. During the upload process the owner has the option of keeping the contribution private so it can be viewed in the context of other data sets and visualized using the suite of MagIC plotting tools. Alternatively, the new data can be password protected and shared with a group of users at the contributor's discretion. Once they are published and the owner is comfortable making the upload publicly accessible, the MagIC Editing Committee reviews the contribution for adherence to the MagIC data model and conventions to ensure a high level of data integrity.
