FAIR Data in Chemistry: Standards, Workflows, and Tools

Principles

Findable: Persistent identifiers (DOI, InChIKey), rich metadata, indexed repositories.

Accessible: Open protocols (HTTPS), clear licenses, controlled access when needed.

Interoperable: Standard formats (SDF, mzML, JCAMP-DX), ontologies (CHEBI, CHEMINF).

Reusable: Provenance, versioning, and domain-specific quality metrics.

Data Types and Formats

Cover molecular structures, reactions, spectra (NMR, MS, IR), chromatograms, assay results, and computational outputs. Use machine-readable schemas and unit consistency (SI).

Metadata and Ontologies

Adopt MIAPE/MIABE-like minimal information sets. Use controlled vocabularies for instruments, conditions, and entities. Capture sample prep and calibration details.

Workflows and Repositories

ELN/LIMS integration with automated export

Deposition to domain repositories (e.g., Chemotion, MassIVE, Zenodo)

Data pipelines with validation and audit trails

Governance and Policies

Define ownership, access policies, retention schedules, and compliance (GDPR). Establish data stewards and review boards.

Automation and Tooling

Use identifiers (InChI, RInChI), templated metadata, and APIs for programmatic access. Validate with schema checkers and unit tests.

Examples

Example 1: FAIR NMR Dataset

Export JCAMP-DX with instrument metadata.

Assign DOIs and deposit in a repository.

Publish schema and validation scripts.

Example 2: Reaction Data Pipeline

Extract from ELN; normalize units and identifiers.

Validate with reaction schema; compute RInChI.

Expose API for internal and external reuse.

Frequently asked questions

How do I start a FAIR program?

Pilot with one dataset type, define schema, automate ingestion, and iterate.

Which repository should I choose?

Prefer domain repositories with DOIs and strong metadata support; fall back to generalist ones with clear schemas.

How to balance openness and IP?

Separate public metadata from restricted data; use embargoes and access controls.

What about proprietary formats?

Preserve originals, but provide open, validated exports for interoperability.

How to ensure data quality?

Define validation rules, run automated checks, and use curation workflows.

How to link publications and data?

Cross-reference DOIs in both directions; include ORCIDs and funding identifiers.

How to handle negative results?

Record with equal rigor; they reduce duplication and improve model training.

What licenses are recommended?

CC-BY or CC0 for data; ensure compatibility with downstream reuse.

How to make data machine-actionable?

Provide APIs, JSON-LD metadata, and documented schemas.

How to measure FAIRness?

Use maturity indicators and automated assessment tools; track over time.
