+ The aggregation processes are continuously running and apply vocabularies as they are in a given moment of time.
+ It could be the case that a vocabulary changes after the aggregation of one data source has finished, thus the aggregated content does not reflect the current status of the controlled vocabularies.
+
+ In addition, the integration of ScholeXplorer and DOIBoost and some enrichment processes applied on the raw and on the de-duplicated graph may introduce values that do not comply with the current status of the OpenAIRE controlled vocabularies.
+ For these reasons, we included a final step of cleansing at the end of the workflow materialisation.
+ The output of the final cleansing step is the final version of the OpenAIRE Research Graph.
- The OpenAIRE graph operates based on a vast variety of hardware and software. As of December 2019, the - hardware infrastructure is the following: -
++ The OpenAIRE Research Graph is operated and maintained at the ICM cutting-edge Technology centre 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. +
