eInfraCentral – Helping users discover and access Europe’s e-infrastructure services
Author:Jelena Angelis
Affiliation: European Future Innovation System (EFIS) Centre

Abstract: 

eInfraCentral (EIC) is a coordination and support action funded from the European Union’s Horizon 2020 research and innovation programme. Its mission is to ensure that by 2020 a broader and more varied set of users discovers and accesses the existing and developing e-infrastructure capacity. The underlying idea is to create a marketplace. 

The project has three-fold objections. First, to structure an open and guided discussion between e-infrastructures to consensually define a common service catalogue. Second, to develop a one stop shop/single-entry point portal for users to browse the service catalogue and enhance the monitoring of key performance indicators that focus on availability and quality of services and user satisfaction. Third, to draw policy lessons for a future European e-infrastructure market place as an extension of the common service catalogue and portal (incorporating a larger number of e-infrastructures).
The poster to be presented during the DI4R is targeted at three audiences: the e-infrastructure services providers (pan-European, regional and national, monothematic or poly-thematic, uni-disciplinary or multi-disciplinary, etc.), b) virtual research environments (VREs), and c) potential users of the e-infrastructure services. 
 The poster aims to answers to some potential questions from the users: 
 “How eInfraCentral project will respond to the need of the European researchers on digital services?”
 “What are we developing in the context of the European Open Science?” 
“What will be offered?”

Data Curation and Provenance for the EUDAT Collaborative Data Infrastructure
Author: Alexander Atamas
Affiliation: Data Archiving and Networked Services (DANS), The Hague, Netherlands

Abstract: 

Data curation plays a significant role in research data management and includes selection, preservation, maintenance, collection and archiving of digital data. Practically, data curation involves establishing and developing long-term storage repositories of digital assets for processing by scientists and other communities. Therefore, data curation within the EUDAT Collaborative Data Infrastructure (CDI) is of great interest for the research community. The presented work describes policies for digital data management as prospective candidates of machine-executable services for EUDAT B2SAFE platform. Data curation policies for two use cases have been developed and mapped to requirements of HERBADROP and GEOFON research projects. It has been demonstrated that the developed policies are strong candidates for implementation in the two use cases. Furthermore, a gap analysis has been carried out against the SCAPE catalogues of policies. 

Provenance of research data is important for tracking origins, ownerships and modifications of data over the data lifecycle. The concept of provenance guarantees that the data sets made available for sharing and exchange are reliable and hence all data transformations and results obtained using the data sets could be reproduced. A HTTP template-based service collecting provenance is developed in our work package to be used by any service from the EUDAT CDI portfolio. The service defines an API for the clients to generate provenance data based on particular templates (Notation3 format) based on the PROV Ontology (PROV-O), which are made available by its operator. The gathered provenance data then can be queried by any interested EUDAT service by using HTTP protocol. The provenance API is demonstrated by applying it to two use cases: the process of persistent identifier (PID) generation in the B2SAFE service; the workflow of the B2SAFE replication.
 
Nowadays, research data often undergo rather intensive lifecycle. Individual data sets for one reason or another are modified, updated or recalculated. Hence, in the scientific community, there is a need for versioning functionality for proper data curation and provenance of research data. Research data sets can constitute a wide spectrum of different formats, for example, papers in PDF format, source codes, log files, images, and videos. Software version control systems like “git” are not able to deal efficiently with large size binary data sets. Therefore, in this work a versioning functionality has been designed and implemented on B2SAFE service. PIDs are employed to identify and access versions independently of physical storage location. In our implementation, a new version is made cross-linked with previous version for the sake of easy navigation between versions. 
 
Having well-designed and clearly expressed data policies including tools for the automated policies execution, as well as having provenance records of data acquisition, transformation and distribution is important for the promotion of data infrastructure platforms such as B2SAFE to the state of purposeful, trusted and well-managed IT services. The EUDAT Collaborative Data Infrastructure is expected to adopt approaches, techniques and tools for data curation developed by EUDAT projects, and to apply them for new research user communities in addition to those involved in EUDAT pilots.

ENES Climate Analytics Service (ECAS),  A Contribution to the EOSC-HUB
Author: Sofiane Bendoukha
Affiliation: Deutsches Klimarechenzentrum (DKRZ)

Abstract: 

Within the EOSC-HUB project,  an integrated catalogue of services, software and data from the EGI federation, EUDAT CDI,  INDIGO-DataCloud and major research e-Infrastructures will be delivered.  The  ENES Climate Analytics Service (ECAS)  is a thematic service, that will take part of the catalogue that constitutes the HUB of the future European Open Science Cloud.

 
The main objective of ECAS is to allow scientific end-users mainly from the climate data community to perform data analysis experiments on large volumes of climate data. 
ECAS follows a Persistent Identifier (PID)-enabled, server-side and parallel approach. Based on experiences within the climate data community, ECAS will open up processing capabilities also for use by other
disciplines.
 
 ECAS relies on different service and software components that proved their efficiency in terms of data management  and processing. 
 The essential components of the ECAS service are: B2HANDLE and Ophidia framework.  On the one hand, Ophidia is a mature, complete and stable service for data analytics, as a result of a long internal validation phase with end-users at Fondazione CMCC. On the other hand,  B2HANDLE is a distributed service, offered
by EUDAT and designed to contribute to data persistency by maintaining opaque,
globally unique Persistent Identifiers (PIDs).
The integration between Ophidia and B2HANDLE plays an important role within the ECAS ecosystem. 
It will enable basic data provenance tracking by establishing PID support through the whole chain, and thereby improving reusability, traceability, and
reproducibility. 
 
Besides B2HANDLE and Ophidia,  ECAS will also rely on other services from EUDAT service suite:
 
- B2DROP to synchronize data outputs between peers 
- B2ACCESS to authenticate and authorize  users 
- B2SHARE to store and share small data sets

Welcome DuraCloud Europe: Secure Storage in the Cloud
Author: Andrea Bollini
Affiliation: 4Science Srl

Abstract:

DuraCloud (http://www.duracloud.org/) is open technology developed by DuraSpace, released [1, 2] in 2010 as open source under the Apache 2.0 license, that makes it easy for organizations and end users to use content preservation services in the cloud. DuraCloud leverages existing cloud infrastructure to enable durability and access to digital content. It is particularly focused on providing preservation support for academic libraries, academic research centers, and other cultural heritage organizations. 
 
Digital preservation is a complex ecosystem. DuraCloud can serve as an important component of this ecosystem, supporting funder policy compliance and enabling best practices in data management to support reuse and data integrity, especially for research data. 
 
The service builds on expert cloud storage providers by overlaying the access functionality and preservation support tools that are essential to ensuring long-term access and durability. DuraCloud offers cloud storage across multiple providers and geographic regions, and offers compute services that are key to unlocking the value of digital content stored in the cloud. DuraCloud allows users to implement preservation policies and data curation strategies for research data providing services that enable digital preservation, data access, transformation, and data sharing.
 
Since 2011 the scholarly community has benefited from the DuraSpace managed DuraCloud service in the United States. To allow a broader world-wide access to these services with close time-zone support and storage proximity, in November 2017 4Science became the first member of the Certified DuraSpace Partner Program, delivering DuraCloud services [3]. Now, from the start of 2018, 4Science provides a managed DuraCloud Service in Europe allowing preservation and content storage service, complying with the European Commission General Data Protection Regulation (GDPR) and offering application support in additional time zones and languages. The DuraCloud service by 4Science provides affordable, transparent, vendor independent, and cost-predictable access to the cloud storage facilities in Europe making it easier for institutions to take advantage of the infinite scalability offered by the cloud.
