Maturity Indicator Identifier: MI-R1.3-faf3eea67a-PCHEM_CHEMICAL_COMPOSITION

This maturity indicator falls under the FAIR principle R1.3: (meta)data meet domain-relevant community standards

The ID of this MI is composed of the following segments (separated by hyphen):

  1. Acronym for "Maturity Indicator"
  2. The FAIR principle this maturity indicator belongs to
  3. The first 10 characters truncated from the SHA-256 hash of the primary reference DOI of this maturity indicator.
  4. A short name to distinguish the maturity indicator definition file

This MI is to indicate if "Chemical composition" is reported by the nano toxicity study data or not.

Maturity Indicator Name: The chemical composition is reported by the nano toxicity study

This maturity indicator is extracted from the following paper Title: Minimal analytical characterization of engineered nanomaterials needed for hazard assessment in biological matrices DOI: https://doi.org/10.3109/17435391003775266

To which principle does it apply?

R1.3

What is being measured?

If the chemical composition is reported by the nano toxicity study data or not.

Why should we measure it?

Chemical composition can be determined, but structural information is difficult to obtain due to complex measurements, ideally this would be provided by manufacturers.

What must be provided for the measurement?

If the value is measured and reported in the data, the following field(s) should appear in JSON-LD metadata:

Field Name Alternative terms
chemical composition chemical_composition,
chemical-composition,
ChemicalComposition

How is the measurement executed?

The chemical composition should be provided in a machine-readable format (JSON-LD) which can be queried using open universal protocol like HTTP.

What is/are considered valid result(s)?

The presence of the field "chemical composition" in the JSON-LD metadata means the measurement is reported which is the valid result.

For which digital resource(s) is this relevant? (or 'all')

For nano toxicity related datasets.

Examples of good practices (that would score well on this assessment)
