The example below shows how the chemical composition can be specified for a substance instance:
{
"$schema": "Composition.schema.json",
"@context": "Composition.schema.json",
"@id": "https://example.org/material/no27_14",
"type": ["Substance"],
"composition": {
"type": ["ChemicalComposition"],
"components": [
{"type": ["Component"], "constituent": "Fe", "amount": {"type": ["MassFraction"], "value": 96.7, "unit": "PERCENT"}},
{"type": ["Component"], "constituent": "Si", "amount": {"type": ["MassFraction"], "value": 3.3, "unit": "PERCENT", "standard_uncertainty": 0.1}},
{"type": ["Component"], "constituent": "C", "amount": {"type": ["MassFraction"], "value": 120, "unit": "PPM"}}
]
}
}
It should result generic RDF representation:
