The short versioneLTER is aligning its CSV-based data reporting format with Darwin Core and Frictionless data packages to make long-term ecological data more FAIR.

Overview

What this was about

Alessandro Oggioni presents the eLTER Research Infrastructure, a pan-European network of long-term ecological sites, and its Data Reporting Format: a zip of CSV tables (method, reference, station, event, sample, licence and data) described by a specification on Zenodo. To improve interoperability, eLTER built a vocabulary of its template terms mapped to Darwin Core where possible and an R function that converts reports into Frictionless data packages. In Q&A he said Darwin Core Data Package largely suffices, but the strong link between data and monitoring sites/facilities is missing.

Why it matters. Bridging long-term ecological monitoring data with biodiversity standards enables cross-infrastructure reuse.

Key ideas

In the room

  • eLTER RI studies structure, processes and functions of terrestrial, freshwater, coastal and transitional ecosystems; entered the ESFRI roadmap about 10 years ago.
  • Sites collect ecosystem, chemical, soil, atmospheric and biological parameters.
  • Data Reporting Format: relational-like CSV tables zipped together; specification published on Zenodo.
  • Vocabulary of template terms with Darwin Core matches and URIs where available.
  • R function generates Frictionless data packages from eLTER reports.
  • Future: automated publication workflows.

Bridging eLTER Data Reporting Format: enabling interoperable biodiversity and ecological data publication across research infrastructures

Alessandro Oggioni

Environmental and biodiversity research infrastructures increasingly face the challenge of mobilising heterogeneous observational data across domain-specific systems, harmonizing it into FAIR data products or digital twins, while preserving semantic richness and machine-actionable interoperability. Within the eLTER Research Infrastructure, ecological and environmental measurements are distributed through the Data Reporting Format (DRF), a structured, multi-table specification designed to support multi-domain standard observational workflows through different entities.

To strengthen semantic interoperability within the broader informatics landscape, a controlled vocabulary has been developed that provides labels and definitions for DRF data specification terms and aligns them with the Darwin Core standard where conceptual equivalence exists. This mapping preserves the native expressiveness of eLTER observational structures while enabling alignment with established biodiversity data exchange mechanisms and improving discoverability across infrastructures and other TDWG-compliant systems.

Building on this, an R-based workflow has been implemented that transforms DRF datasets into Data Packages. This packaging layer facilitates FAIR and machine-actionable (“robot-ready”) data publication, while enabling downstream integration into biodiversity data infrastructures without requiring convergence toward a single monolithic data model.

This work demonstrates how infrastructure-specific reporting standards can remain fit-for-purpose while participating in a coordinated biodiversity data ecosystem through explicit semantic alignment and reusable transformation workflows. The approach provides a practical contribution to strengthening interoperability.
