Common Ontology for Stable Isotope Data from Australian Research Collaboration

A common ontology for stable isotope data created by CSIRO, Geoscience Australia, ANSTO, and the National Measurement Institute. The ontology aims to facilitate the harmonization and integration of disparate stable isotope datasets, which are used to trace processes in natural, managed, and industrial systems. This project received investment from the Australian Research Data Commons as part of their Food Security Data Challenges program.

Use Cases

• Harmonizing disparate stable isotope datasets based on the common ontology framework
• Tracing environmental processes and flows in natural systems based on isotope measurements
• Integrating stable isotope data across scientific domains and applications for 'big data' analysis
• Increasing discoverability and accessibility of public sector stable isotope data for reuse

Strengths

• Developed by principal custodians and generators of stable isotope data in Australia: CSIRO, Geoscience Australia, ANSTO, and NMI
• Addresses a 550% increase in geoscience data holdings at Geoscience Australia from July 2018 to July 2024
• Published in a peer-reviewed journal (Applied Geochemistry, Volume 198, 2026)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and dataset size are unknown, which may limit suitability assessment
