Maturity Indicator Identifier: MI-R1.3-88b52fa7b8-AGGLOMERATE_SIZE_QUALIFIER

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 the agglomerate size "qualifier" is reported by the nano toxicity study data or not.

Maturity Indicator Name: The agglomerate size qualifier is reported by the nano toxicity study

This maturity indicator is extracted from the following paper Title: Metadata Stewardship in Nanosafety Research: Community-Driven Organization of Metadata Schemas to Support FAIR NanoScience Data REF:

To which principle does it apply?


What is being measured?

If the agglomerate size qualifier is reported by the nano toxicity study data or not.

Why should we measure it?

This is one of the nano particle's (NP) agglomeration-related metadata relevant for delivered dose (DD) assessment as a means to facilitate correct interpretation of in vitro bioassays and support data reuse (case study value: Hydrodynamic diameter).

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
agglomerate size qualifier agglomerate-size-qualifier,

How is the measurement executed?

The "agglomerate size qualifier" 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 "agglomerate size qualifier" 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)
