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 nanomaterial's size distribution is reported by the nano toxicity study data or not.

This maturity indicator is extracted from the following paper Title: caLIBRAte nano risk governance D5.3 document on quality criteria for Data Reference Website: http://nanocalibrate.eu

Size distribution: a list of values which define the relative amounts of particles present, sorted according to size including modality, peak magnitude, minimum and maximum.

R1.3

If the nanomaterial's size distribution is reported by the nano toxicity study data or not.

Data completeness may be considered to include, amongst other kinds of data and metadata, the extent of nanomaterial characterization, both physicochemical and biological, under a specified set of experimental conditions and time points. It may also encompass the degree to which experimental details are described, as well as the availability of raw data, processed data, or derived data from the assays used for nanomaterial characterization. The caLIBRAte project determined minimum information checklists for the information that should be reported, including the one in this maturity indicator, to determine data usefulness for developing/testing computational models.

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

The nanomaterial's size distribution should be provided in a machine-readable format (JSON-LD) which can be queried using open universal protocol like HTTP.

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

For nano toxicity related datasets.
