eLTER Cyber infrastructure - developing the Research Infrastructure technical backbone

We live in a world characterized by rapid social, economic, and ecological changes, facing important environmental challenges such as climate change, biodiversity loss, and pressures on natural resources. Addressing these issues requires world-class ecosystem research, driven by a well-connected, extensive community of experts, supported by advanced sites and facilities, and supported by openly shared and easily accessible data alongside capacity building programs. This is the mission of the eLTER Research Infrastructure (eLTER RI). Currently, in its preparatory phase, eLTER is on the path to becoming a fully-fledged Research Infrastructure. Central to this endeavor is the eLTER Cyber infrastructure (CI), which serves as the technical backbone for all data management and information services within eLTER RI.
The Cyberinfrastructures aim is to support workflows and processes with modern software and cloud solutions to accommodate the requirements of the eLTER RI. CI is involved in the entire data life cycle, from ingestion to preservation and is composed by different components targeting different users, including data providers, data managers, and data users, as well as other service providers and research infrastructures.
The primary requirement is the implementation of state-of-the-art data management, adhering to the FAIR principles. eLTER CI envisions various data management solutions and implementations, designed to be interconnected, forming a valuable collection of well-integrated tools and services. To this end, eLTER CI integrates EUDAT services, such as B2Share, to facilitate data integration workflows. Other solutions, like the Sensor Management System combined with a time series data management system, leverage the B2Inst registry for scientific instruments.
This work provides an overview of the current system architecture and planning, offering a comprehensive insight into how digital services within the European landscape can be integrated into complex research infrastructures.

我们所处的世界正经历着社会、经济与生态的快速变革，同时面临气候变化、生物多样性丧失、自然资源压力等严峻环境挑战。应对此类问题亟需顶尖的生态系统研究，其依托于互联互通、规模庞大的专家共同体、先进的观测站点与设施，辅以开放共享、易于获取的数据资源与能力建设项目。这正是eLTER研究基础设施（eLTER Research Infrastructure, eLTER RI）的使命所在。
目前，eLTER仍处于筹备阶段，正朝着成为成熟完备的研究基础设施迈进。此项工作的核心是eLTER网络基础设施（Cyber Infrastructure, CI），它作为eLTER RI内部所有数据管理与信息服务的技术支柱。
该网络基础设施的目标是借助现代化软件与云解决方案支撑各类工作流与流程，以适配eLTER RI的各项需求。CI覆盖数据从摄取、处理到留存的全生命周期，由面向不同用户群体的多个组件构成，服务对象涵盖数据提供者、数据管理者、数据使用者，以及其他服务提供商与研究基础设施。
其首要要求是落地顶尖水准的数据管理实践，并严格遵循FAIR原则（FAIR principles）。eLTER CI旨在打造各类数据管理解决方案与落地实践，实现各组件间的互联互通，最终形成一套高度整合的优质工具与服务集合。为此，eLTER CI集成了EUDAT服务（EUDAT），如B2Share，以优化数据集成工作流。其他解决方案则将传感器管理系统（Sensor Management System）与时序数据管理系统相结合，借助B2Inst注册表实现科学仪器的规范化管理。
本研究概述了当前的系统架构与规划方案，全面阐释了欧洲地区的数字化服务如何融入复杂的研究基础设施。
