OpenAIRE in the European Open Science Cloud (EOSC)OpenAIRE
Openness is the success factor for EOSC. OpenAIRE has been working in delivering an open access scholarly communication in Europe for the past 10 years and we now present how our work fits into the EOSC core developments
The Ascent of Open Science and the European Open Science CloudTiziana Ferrari
Open science is becoming more and more part of the daily practice in conducting science. Around the world, researchers are increasingly aware of the value and importance of open science. As scientific research becomes highly data-driven and dependent on computing, scientists are conscious of the growing need to share data, software and infrastructure to reduce wasteful duplication and increase economies of scale. In an ideal world, every step of the research process would be public and transparent – the full methodology and all the tools used, as well as the data, would be accessible to the public and all groups without restriction, enabling reproducibility and refinement by other scientists.
This presentation will show case a number of success stories indicating how federated digital infrastructure, that have been sustained by the member states and the European Commission, have become an indispensable tool to enable collaboration ad sharing.
The European Open Science Cloud was launched by the European Commission in 2016 aiming to (1) increase the ability to exploit research data across scientific disciplines and between the public and private sector, (2) interconnect existing and new digital infrastructures in Europe and (3) support open science.
The presentation showcases how open data, open data analytics and open e-Infrastructures like EGI (https://www.egi.eu/) have been key enables of scientific discoveries from the discovery of gravitational waves with LIGO-VIRGO to drug design with the molecular modelling tools of WeNMR.
EOSC-hub (https://www.eosc-hub.eu/) - the first and the largest of the EOSC implementation projects of the H2020 funding programme, has succeeded in delivering some of the building blocks like the EOSC portal and Marketplace, tools and processes for federating data and services providers, harmonized policies, a federated AAI infrastructure, Competence Centres to support research infrastructures in their complex digital needs, interoperability guidelines and the Early Adopter Programme to provide expert support and service capacity to research projects.

Starting in 2023, the US National Institutes of Health (NIH) will require institutes and researchers receiving funding to include a Data Management Plan (DMP) in their grant applications, including the making their data publicly available. Similar mandates are already in place in Europe, for example a DMP is mandatory in Horizon Europe projects involving data.
Policy is one thing - practice is quite another. How do we provide the necessary information, guidance and advice for our bioscientists, researchers, data stewards and project managers? There are numerous repositories and standards. Which is best? What are the challenges at each step of the data lifecycle? How should different types of data? What tools are available? Research Data Management advice is often too general to be useful and specific information is fragmented and hard to find.
ELIXIR, the pan-national European Research Infrastructure for Life Science data, aims to enable research projects to operate “FAIR data first”. ELIXIR supports researchers across their whole RDM lifecycle, navigating the complexity of a data ecosystem that bridges from local cyberinfrastructures to pan-national archives and across bio-domains.
The ELIXIR RDMkit (https://rdmkit.elixir-europe.org (link is external)) is a toolkit built by the biosciences community, for the biosciences community to provide the RDM information they need. It is a framework for advice and best practice for RDM and acts as a hub of RDM information, with links to tool registries, training materials, standards, and databases, and to services that offer deeper knowledge for DMP planning and FAIR-ification practices.
Launched in March 2021, over 120 contributors have provided nearly 100 pages of content and links to more than 300 tools. Content covers the data lifecycle and specialized domains in biology, national considerations and examples of “tool assemblies” developed to support RDM. It has been accessed by over 123 countries, and the top of the access list is … the United States.
The RDMkit is already a recommended resource of the European Commission. The platform, editorial, and contributor methods helped build a specialized sister toolkit for infectious diseases as part of the recently launched BY-COVID project. The toolkit’s platform is the simplest we could manage - built on plain GitHub - and the whole development and contribution approach tailored to be as lightweight and sustainable as possible.
In this talk, Carole and Frederik will present the RDMkit; aims and context, content, community management, how folks can contribute, and our future plans and potential prospects for trans-Atlantic cooperation.
Data policy must be partnered with data practice. Our researchers need to be the best informed in order to meet these new data management and data sharing mandates.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

1. EERIS Network description. Scope of the
project
4. Reputation is the recognition by other
people/entities of some characteristic
or ability (Merriam-Webster
dictionary);
Few attributes are more important to
identity and trust than reputation
(Arun and Carmichael, 2017);
Reputation could be seen as a global
perception of an entity's behavior
based on the trust established by the
other entities in a system.
In order to guarantee an objective measurement of
reputation, a reputation management system has to be
designed:
- a possible approach is to establish a central authority to act
as the agent of trust, but such a solution does not eradicate
the root cause of mistrust
- another approach: a distributed reputation system based on
Blockchain; to measure an individual’s or an institution’s
propensity to do what they promise, data tracked for past
performance on a Blockchain could be used, while access to
the data on a Blockchain becomes a new verifiable basis for
reputation, which can visibly demonstrate trustworthiness to
their potential clients and partners.
2.1. Reputation
The Blockchain is a type of Distributed Ledger Technology (DLT), an append-only chain-like data
structure, made out of signed and timestamped blocks that contain the transactions (Holotescu
and Vasiu, 2020).
5. 2.2. Open Research
Our approach follows the principles of Open Research/Science recently defined by UNESCO
Recommendations on Open Science, European Union's Open Science policy, and Open Science
Knowledge Hub Romania.
UNESCO Recommendations on Open Science, published in November 2021:
“Open science increases scientific collaborations and sharing of information for the benefits of
science and society; also opens the processes of scientific knowledge creation, evaluation and
communication to societal actors beyond the traditional scientific community.”
Blockchain and Open Data share similar principles such as the promotion of transparency,
equality in information knowledge and access, as well as the reorganisation of data exchange
between a number of parties (data.europa.eu, 2018).
The decentralization brought by Blockchain enables researchers to build their own open
ecosystem for research data, metadata, and communication that follows the philosophy of
open research, thus everyone can openly participate, collaborate, and contribute to science.
The results of these activities, such as research data, processes, studies, and methods, are
freely available so that they can be reused and reproduced (Leible et al., 2019).
6. The implemented reputation mechanism aims to increase openness, impact, and technology
transfer of research infrastructures (RIs) and is designed not only to measure reputation, but also
to make it more visible and, above all, to provide an ecosystem for its growth.
The reputation mechanism designed and implemented consists of a Blockchain (Hyperledger
Fabric) infrastructure for EERIS - EERIS Blockchain Infrastructure (EBI), which communicates with
the platform through an API (Application Programming Interface).
The reputation factor will result by weighting the dynamics of the RI data stored on the
Blockchain, over time.
3. Blockchain-based Reputation Infrastructure
for Open Research: design and implementation
7. Proposed solution
The aim of the project is to create a reputation system which can be integrated with the
current EERIS platform without the need to redesign or revamp the whole platform, thus a
set of APIs which can be integrated with the current platform was proposed in 2 steps:
1. Integrate existing functionality on the platform with the designed Blockchain system to
build dynamism through the traceability of the activities of each RI based on which the
reputation is build.
2. Integrate certifications of data contributed through collaborations of the RIs and
multiparty contracts.
The storage of data (1) / interaction (2, 3, 4) of the research infrastructures (RI) on
Blockchain ensures:
1. immutability, transparency, traceability and audit of
data / collaborations stored for each RI at certain
periods of time or when changes appear for the
number of experts, equipment, services, and visits;
thus, the dynamics of each RI are retained
2. registration and dynamics of contracts for
technology transfer with other RIs and third parties
3. openness of research by publishing open data sets
for reuse in other projects by other RIs, entities
4. copyright protection / certification / licensing /
notarization – by storing certificates for articles,
data, projects, open educational resources, training,
internships, milestones, etc.
8. EERIS Blockchain Infrastructure (EBI)
- The PoC network consist of 2
organizations, each having their
own Certificate Authorities,
Peers, Orderers;
- The network runs a RAFT
ordering service and a channel
containing 2 chaincodes for the
RIs and separately for
certificates is being used.
- A service exposing endpoints
for interacting with the network
as well as managing identities
and IPFS pinning.
10. The implemented EERIS Blockchain Infrastructure (EBI) was presented, analyzed and piloted with
representatives of three universities:
a) Politehnica University of Timișoara (UPT) - Lecturer Dr. Vlad Mihăescu, Director of the Center
for Innovation and Technology Transfer – for creating and tracing a technology transfer
contract between the center and a company;
b) West University of Timișoara (UVT) - Lecturer Dr. Cristian Cira, coordinator of the
Postgraduate Program “Entrepreneurship in Blockchain” – for storage and verification of a
document on Blockchain, respectively of the certificate of completion of the postgraduate
program;
c) “Vasile Goldiș” University of Arad (UVVG) - Assoc. Prof. Antoanela Naaji, Director of the
International Relations Department – for storage and open access to technical or medical
research data for participants in international webinars.
The piloting has demonstrated the interest of the universities for the new EERIS facilities issued
by EBI and that they would be included in the current activities, for contracts with third parties,
research projects for open access to research data, programs for which the certificates of
completion are stored on the Blockchain.

• Existing resources: number of researchers,
equipment, services offered, data sets
(available and downloaded)
• Information update: first and latest update
• Impact on visitors: message threads, total
number of visits, latest visit
• Collaborations: value (interval) for contract,
duration of collaboration, rating of the
beneficiary/beneficiaries for the
Example 2:
• Resources: 10 researchers, 10 pieces of equipment, 10 different services offered,
10 open data sets available, 5 data sets downloaded
• Updates: added to platform – 10 years ago, latest update – 1 year ago
• Impact: 100 visits since creation, latest visit one month ago, 10 received
messages, 10 responding messages
• Collaborations:
• Contract 1: 5000 Euro, 12 Months, final rating: 4/5
• Contract 2: 15000 Euro, 24 Months, final rating: 3/5
• If all coefficients have the value 1, total:
• Resources = 1*10 + 1*10 + 1*10 + 1*10 + 1*5 = 45
• Updates = 1*120 – 1*12 = 108
• Impact = 1*100 – 1*1 +1*(10+10) = 119
• Collaborations = (10-3 * 5000 + 1 * 12 + 20 * 4) + (10-3 * 15000 + 1*24 + 20 * 3) = 97
+ 99 = 198
• Reputation total = 455
6.2. Modelling the Reputation factor –
updated version
18. The implemented reputation mechanism aims to increase openness, impact, and technology transfer of
research infrastructures (RIs) and is designed not only to measure reputation, but also to make it more visible
and, above all, to provide an ecosystem for its growth.
The EBI infrastructure is flexible and extensible, to which all or only a part of the research infrastructure (RIs)
can be connected, for piloting and familiarization. EBI could also be installed for individual or groups of
research or academic institutions.
EBI ensures the immutability, traceability, and audibility of RI data. In this way, the stored open research data
meets the principle of FAIR (Findable, Accessible, Interoperable, and Re-usable), and data storage and
management being performed according to the principle of TRUST (Transparency, Responsibility, User focus,
Sustainability, and Technology) (Lin et al ., 2020).
Future work requires a more extensive performance analysis based on a set of different network settings and
distribution of nodes.
Also, the implemented system can ensure open access to the scientific results (including data) of the RI, and in
the future, the mechanisms could be used also for the evaluation, classification, ranking, financing, and
matching partners.
For further expanding the network and bridging the information into other applications (eg. Brainmap – online
community for researchers), a SSI management system needs to be integrated for sharing identities across
platforms (eg. TrustID, Hyperledger Aries).
The activities towards open research/data on EERIS could contribute to the scientific portfolios of the
academics/researchers and be taken into account for promotion.
