UKRI All rights reserved EPOS Vision EPOS vision is that the integration of the existing national and trans-national research infrastructures will increase access and use of the multidisciplinary data recorded by the solid Earth monitoring networks, acquired in laboratory experiments and/or produced by computational simulations. The establishment of EPOS

will foster worldwide interoperability in the Earth sciences and services to a broad community of users. [https://www.epos-ip.org/about/what-epos] UKRI All rights reserved EPOS Mission EPOS mission is to integrate the diverse and advanced European Research Infrastructures for solid Earth science, and build on new e-science opportunities to monitor and understand the dynamic and complex solid-Earth System. EPOS will identify existing gaps and promote implementation plans with environmental, marine and space science to help solve the grand challenges facing the Earth and its inhabitants.

Sarah is a project PI and part of the DeepNL program. She wants to create a model with the purpose of simulating the surface subsidence above the Groningen Gas field for the next decades. The task: Bring together numericalThe model requires input from: Geoscience data and a) Satellite-based surface services

fromsubsidence across data from the past 30 years Europe in a way that b) Location, time,them magnitude, focal mechanism allows to beand easily of earthquakes in the area combined. c) A geological model of the subsurface based on The goal: seismic and

Make our data Interoperable Integrate = "ability of a system to work with or use the parts or equipment of another system [Merriam-Webster] Data interoperability addresses the ability of systems and services that create, exchange and consume data to have clear, shared expectations for the contents, context and meaning of that data.

EPOS FAIR Data - Findable 1. (meta)data are assigned a globally unique and eternally persistent identifier. 2. data are described with rich metadata. 3. (meta)data are registered or indexed in a searchable resource. 4. metadata specify the data identifier. [https://www.force11.org/group/fairgroup/fairprinciples] UKRI All rights reserved EPOS FAIR Data - Accessible 1. (meta)data are retrievable by their identifier using a standardized communications protocol. A. the protocol is open, free, and universally implementable. B. the protocol allows for an authentication and authorization procedure, where necessary.

2. metadata are accessible, even when the data are no longer available. [https://www.force11.org/group/fairgroup/fairprinciples] UKRI All rights reserved EPOS FAIR Data - Interoperable 1. (meta)data use a formal, accessible, shared, and broadly applicable language for knowledge representation. 2. (meta)data use vocabularies that follow FAIR principles. 3. (meta)data include qualified references to other (meta)data. [https://www.force11.org/group/fairgroup/fairprinciples] UKRI All rights reserved EPOS FAIR Data - Reusable 1. meta(data) have a plurality of accurate and relevant

attributes. A. (meta)data are released with a clear and accessible data usage license. B. (meta)data are associated with their provenance. C. (meta)data meet domain-relevant community standards.
