www.epos-ip.org EPOS is a long-term plan to facilitate integrated use of harmonized data, data products, and facilities from distributed research infrastructures for solid Earth science in Europe. Funded by the Horizon 2020 ESFRI-Research Infrastructure Programme of the European Commission EPOS is developing a holistic, sustainable, multidisciplinary research platform to provide coordinated access to harmonized and quality controlled data from diverse Earth science disciplines, together with tools for their use in analysis and modelling.

Make the EPOS service platform operational EPOS Timeline 2002 2008 2010 2014 2015 2019 2015 EPOS PP - agreement on: (1) technical design of the EPOS architectural framework (2) Legal governance and financial models Make the EPOS service platform operational Sustainability as EPOS ERIC (European Research Infrastructure Consortium) Funded by member fees of participating countries The EPOS Preparatory Phase was key for the implementation of the pan-European research infrastructure for solid Earth science that EPOS will become. The EPOS Preparatory Phase project had the ambitious goal of creating the conditions for the integration of existing and future national and international research infrastructures (RIs) in Europe with the final goal of improving access to data, products and services. EPOS PP achievements: the technical design of the Thematic and Integrated Core Services has been shared and agreed with the communities, successfully engaged during the preparatory phase; the legal, governance, and financial models have been discussed and agreed with the governmental representatives and research institutions successfully engaged during the preparatory phase; It succeeded in integrating the solid Earth European scientific community providing a global perspective and an effective possibility to exploit results;

EPOS functional architecture NRI: National Research Infrastructures (disciplinary): main data providers TCS: Thematic Core Services: disciplinary, integration of NRI and other data ICS: Integrated Core Services: Central Hub (ICS-C) and Distributed Services (ICS-D) ECO: Executive Coordination Office

The EPOS Implementation Project concept and approach Disciplinary Workpackages (10/17): Seismology Near-Fault Observatories GNSS Data & Products Volcano Observations Satellite Data Geomagnetic Observations Anthropogenic Hazards Geological Information & Modeling Multi-scale Laboratories Geo Energy Test Beds for Low Carbon Energy

TCS Thematic Core Services Community-driven Disciplinary (development of standardised disciplinary metadata if not yet existing) Harmonisation of metadata within the workpackages (which data are interesting and suitable for EPOS?) Harmonisation across workpackages describing the same type of data (e.g. near-fault observatories have seismic data) Metadata exchange with ICS required (central or distributed servers with API)

ICS Integrated Core Services The heart of EPOS: ICS Central user interface/ Web Portal for data discovery and access to data, data products, software and services including access to external services like HTC computing facilities and visualisation services (ICS-D) the user interface (or web portal), where the integrated set of DDSS provided by TCS, the computational and visualization tools, and the collaborative functionalities are made available and accessible to end-users (i.e. scientists, policy maker, citizens); the API layer, which ensures programmatic access to EPOS ICS-C functionalities by providing a machine-to-machine interface; the Metadata Catalogue, which contains all the information needed to run the EPOS ICS-C system (i.e. metadata about Users, Software, Resources, Data). The metadata catalogue is the view of the ICS-C system over the outer world; the system management software is a set of software modules (e.g. system orchestrator, message bus and others) that provide the functionalities required to satisfy users requests; the interoperability layer is a set of technologies, partially provided by TCS (e.g. web-services to access TCS data or data products) and partially provided by ICS (e.g. connectors to map TCS web services response to the ICS metadata catalogue), that enable the ICS-TCS communication and in particular the exchange of metadata and other information. Such layer is also intended to integrate visualization and computational resources from ICS-D (see next section).

Challenges for EPOS To manage heterogeneity in data access across disciplines (i.e. data streams vs. data files) To harmonise data and metadata standards To harmonise vocabulary To bridge the gap between different maturity of data management and data curation across the diciplines

Example: TCS Seismology ORFEUS: Observatories and Research Facilities for European Seismology, EIDA: European Integrated Data Archive; EMSC European-Mediterranean Seismological Centre; EFEHR European Facilities for Earthquake Hazard and Risk, Fully standardised data and metadata, large data streams Global intitiatives (e.g. FDSN) NRIs: ORFEUS (including EIDA), EMSC, EFEHR Products and Services: Data Services: e.g. seismic waveforms (including strong-motion) and metadata from permanent and temporary networks and from ocean-bottom seismometers, etc. Product Services: locations, magnitudes and other parametric earthquake information collections for recent and historical earthquakes, etc. Earthquake Hazard and Risk Services: access to data products, results, computation tools and support, including hazard maps, risk maps, scenarios and basic geological and geotechnical data Computational Seismology services: access to IT platforms allowing computational workflow definition and execution for data- and CPU-intensive processing, massive data mining, and visualization …

Example: TCS Multiscale Laboratories Multi disciplinary: paleomagnetics, analogue modelling, rock mechanics, geochemistry, etc. Only static, mostly small data („long-tail“) Few disciplinary metadata portals or NRIs Workflow: Development of metadata standards for each discipline if not existing Development of a central TCS „Portal“ with API for communication with ICS Integration of metadata of data products via an XML Metadata Editor or scripts Data access via DOI-referenced data publications in data repositories Data and Products: analytical and experimental data and data products on volcanic ashes and magmatic rocks, experimental data and data products on rock properties, paleomagnetic data, and data on analogue modelling materials and experiments Physical Access: transnational access to experimental and micro-analytical facilities

Challenges for EPOS - 2 Provide a user interfaces that seamlessly integrates different types of data Integrate different types of services provided by the TCS communities (HPC-access, visualisation and others) General organisation: standardisation, harmonisation, quality control „Types of data“= groß & klein ; kontinuierliche Datenströme und Dateien
