Maturity Indicator Identifier: MI-R1.3-99c4a218fe-LS_RHIZOSOMAL_EXTRACTABLE_ELEMENTS

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 water extractable elements (Si, Ca, Mg, Fe, Al, Mn) of the rhizosomal system (in liquid-surface exposure scenarios) is reported by the nano toxicity study data or not.

Maturity Indicator Name: The water extractable elements (Si, Ca, Mg, Fe, Al, Mn) of the rhizosomal system (in liquid-surface exposure scenarios) is reported by the nano toxicity study.

This maturity indicator is extracted from the following paper Title: Harmonizing Across Environmental Nanomaterial Testing Media for Increased Comparability of Nanomaterial Datasets DOI: https://doi.org/10.1039/C9EN00448C

To which principle does it apply?

R1.3

What is being measured?

If the water extractable elements (Si, Ca, Mg, Fe, Al, Mn) of the rhizosomal system (in liquid-surface exposure scenarios) is reported by the nano toxicity study data or not.

Why should we measure it?

Calculate ionic strength/divalent versus monovalent to determine colloidal stability, specific adsorption to NM and soil surfaces (PO4, Ca), nutrient availability, metal speciation.

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
rhizosomal system extractable elements rhizosomal_system_extractable_elements,
rhizosomal-system-extractable-elements,
RhizosomalSystemExtractableElements

How is the measurement executed?

The "rhizosomal system extractable elements" 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 "rhizosomal system extractable elements" 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)
