Updates and future plans at the World Data Centre for Geomagnetism, Edinburgh

The World Data Centre for Geomagnetism, Edinburgh (WDC) is a long-standing repository of geomagnetic data and data products. Its holdings include geomagnetic observatory time-series data, magnetic survey records, geomagnetic indices and models. Analogue records in the form of paper magnetograms, observatory yearbooks and other publications are also archived. The WDC is a member of the World Data System and is currently applying for Core Trust Seal status. The data held on behalf of the geomagnetic community are freely accessible and openly shared. The first step toward FAIR data principles is to make the data Findable for both humans and computers. Recently the WDC has been working with the European Plate Observing System (EPOS) to develop a metadata schema for geomagnetic observatory data. A metadata database has been populated and a webservice allowing programmatic access has been developed. The internal systems and user interface of the WDC have been updated to utilise this database. The new metadata database will be described and examples of its use given. The WDC aims to continue to improve the services offered to the geomagnetism community. Future plans to develop support for historic digitised data sets and a new monthly mean database will be introduced.
