Open Science is gradually becoming the modus operandi in research practices, affecting the way researchers
|
|
collaborate and publish, discover, and access scientific knowledge.
|
|
Scientists are increasingly publishing research results beyond the article, to share all scientific
|
|
products (metadata and files) generated during an experiment, such as research data, research software, experiments.
|
|
They publish in scholarly communication data sources (e.g. institutional repositories, data archives,
|
|
research software repositories), rely where possible on persistent identifiers (e.g. DOI, ORCID, Grid.ac, PDBs),
|
|
specify semantic links to other research products (e.g. supplementedBy, citedBy, versionOf), and possibly
|
|
to projects and/or relative funders.
|
|
By following such practices, scientists are implicitly constructing the Global Open Science Graph, where
|
|
by "graph" we mean a collection of objects interlinked by semantic relationships.
|
|
<br><br>
|
|
The OpenAIRE Graph includes metadata and links between scientific products (e.g. literature,
|
|
research data, research software, and "other research products"), organizations, funders, funding streams, projects,
|
|
communities, and (provenance) data sources - the details of the <a
|
|
href="https://zenodo.org/record/2643199#.XOqdstMzZ24" target="_blank">graph data model</a> can be found
|
|
in Zenodo.org.
|
|
<br><br>
|
|
The Graph is available and obtained as an aggregation of the metadata and links collected from ~70.000
|
|
trusted sources, further enriched with metadata and links provided by:</p>

The OpenAIRE Graph is operated and maintained at the <a

|
|
with the facilities and staff guaranteeing robust operation of the whole system.

Okeanos SuperComputer hosting the graph consists of 26016 cores in total providing 1082 Tflops/s.
|
|
Whole setup is energy efficient with 1.554 Gflops/Watts Power Efficiency resulting in 160th place on the
|
|
"Top500 by energy-eficiency" list (as of 2019).

ICM supports the continuous operation of the infrastructure including data aggregation, deduplication,
|
|
inference and provision ensuring seamless 24/7 system uptime and availability.
|
|
System administration activities cover hardware maintenance and provisioning of the new computational
|
|
resources, providing High Availability solutions to address resilience to failures by service-level
|
|
redundancy and Load Balancing to distribute workloads uniformly across servers.
|
|
The most crucial parts of the persisted graph are covered with backups along with well defined restore
|
|
procedures.
|
|
All the monitoring activities rely on an aggregated system-level monitoring accessible via various
|
|
dashboards giving the better overview of system stability and potential requirements for system elements
|
|
extension.
|
|
System level monitoring is supplemented with monitoring availability of all the publicly accessible
|
|
endpoints.
|
|
Hence, the offer of the public API of OpenAIRE to third parties, is of high-standards.

All the maintenance operations undertaken by experienced system administrators are founded on well

established routines and emergency maintenance procedures.
