1 EUDAT - Open Data Services for Research Johannes Reetz EUDAT operations Max Planck Computing & Data Centre Science Operations Workshop 2015 ESO, Garching 24-27th November 2015 EUDAT receives funding from the European Union's Horizon 2020 programme - DG CONNECT e-infrastructures. Contract No

2 Research Infrastructures Where are we going? Research Infrastructure trends & challenges Internationalisation Diversification Increasingly relying on ICT Data deluge Complexity Trust, Authenticity Citation, Credits Open Access Open Data European RIs: Around billion investment middle age 19th century 20th century 21st century 2

3 An e-infrastructure solution for pan-european Research Data Challenges All Research communities and RIs are facing similar data challenges Where to store (big) data? How to keep-it meaningful over time? How to share data? How to publish it? How to register data objects? How to connect them? How to find it? How to access it? How to transfer it? Solutions needed at global level collaboration needed Exploitation of synergies Some services are common to many communities / research domains Reduce investment and operational cost Collaborate on optimizing standards for APIs, MD, DO Identity profiles, policies 3

4 EUDAT consortium (2011, 2015) EUDAT offers common data services, supporting multiple research communities as well as individuals, through a geographically distributed, resilient network of 35 European organisations e-science Data Factory 4

21 Example: Safe Replication The ideal solution to: eudat.eu/b2safe replicate research data into secure data stores archive and preserve research data in the long-term bring data permanently close to powerful compute resources co-locate data with different communities benefit from economies of scale Features: large-scale storage robust and highly available permanent PIDs 21

23 Who? Groups, Communities and Centres who want to make their data referencable in a stable way What? Follows policies to register data and make it long term refer- and citable Reliability through mutual PID mirroring, Handle Prefix Registrars from epic or other DONA MPAs are partners of EUDAT. Provides the abstraction layer between a globally unique persistent identifier and physical location of data objects Machine readable via HTTP RESTful API Why Handles? Stable globally unique IDs, stable cross-links Technology Agnostic Simple Integration Development activity Develop policies for the B2HANDLE service (e.g. PID namespace mngmt) Consolidate the PID record profile for the CDI Define PID Information Types for data, metadata, collection records Integrate with Data Type Registry service Consolidate B2HANDLE API library with EUDAT API library 23

24 Worldwide PID system, a DNS for Data being built DONA dona.net Representatives from all continents Stewards of the Handle System Worldwide MPAs with RAs IDF, epic, CNRI, etc. A worldwide system to register digital objects via Handles similar to the assignment of FQDNs to compute resources having IP-addresses. Need to be able to identify and test integrity and authenticity of data, relations to meta data, apps, services etc. The Handle System offers a powerful solution. DONA is a foundation under Swiss law to make the Handle System independent from CNRI. Federation of Multi-primary Prefix Administrators (MPA) and Prefix- Registration Authorities are being established. 24
