The Geomagnetism community offers a broad portfolio of "web services". Geomagnetism work under EPOS has also seen the creation of a community resource for Geomagnetic Observatory metadata, a system which supports a number of the data services. The metadata system is still being developed. Further input from the community will be needed to finalise the system.
EPOS provides data, data products, software and models to its users. Collectively these are known as services. Each scientific domain in EPOS has decided which services to offer.
