The Geomagnetism community will offer a broad portfolio of "web services". Geomagnetism work under EPOS will also see the creation of a community resource for Geomagnetic Observatory metadata, a system that will support a number of the data services. The metadata system is at the design phase and comments about its suitability are sought from the community.
EPOS will provide data, data products, software, models and, in some cases, computational facilities to its users. Collectively these are known as services. Each scientific work package in EPOS has decided which services to offer.
