The CDGP [https://cdgp.u-strasbg.fr], Data Center for Deep Geothermal Energy, was created in 2016 by the LabEx G-Eau-Thermie Profonde (continuing now in ITI GeoT) [https://geot.unistra.fr/], to archive the high-quality data collected in the Upper Rhine Graben geothermal sites and to distribute them to the scientific community for R&D activities, taking Intellectual Property Rights into account. It manages seismological (catalogues, waveforms, focal mechanisms), seismic, hydraulic, geological, and other data related to anthropogenic hazard from different phases of a geothermal project. Up to now, data are related to Soultz-sous-Forêts, Rittershoffen, Vendenheim and Illkirch.
The CDGP was designed (1) as a store to archive and distribute isolated data and (2) as a gateway to access data handled by another datastore. Indeed, other data can be found elsewhere: in official national stores like Minergies [http://www.minergies.fr/en]or InfoTerre [https://infoterre.brgm.fr/], in academic or project-related stores like BCSF-Renass [https://renass.unistra.fr] or GFZ Data Services [https://dataservices.gfz-potsdam.de/portal/], or even using an internal data service like the one provided by the EOST’ seismological data center CDS [https://eost.unistra.fr/plateformes/cds].
A major objective is to give access to data – even outside the CDGP; they are described in metadata records, where links to the resource are set. Access rights can be controlled and granted either by the destination store, or - if requested - by the CDGP. In this latter case, access rules are defined by the center providing data, and access is validated by the CDGP and request is made only if it is granted. Another advantage is to avoid data duplication and therefore disk space, follow-up of updates, access rights management. If possible, these remote data are also provided as the local data to the EPOS Anthropogenic Hazard platform [https://tcs.ah-epos.eu/]
This feature is useful for users who do not need to search for data on several different sites. It is also useful for data providers and centers who wish to make their data known while keeping control of data access, or need to do special actions before giving access to their data.
