Regarding the UseCase of ChemicalSubstance, I would like to use it as a property of a hypothetical Crystallization Experiment BioSchema. Thus, I believe that by adding few properties (see below) to ChemicalSubstance, it could be used, with MANY cardinality as a Chemical Solution in other possible experimental BioSchema.

New proposed properties

  • concentration; The quantity of solute present in a given quantity of solution. ONE
  • unitOfMeasure; A named quantity in terms of which other quantities are measured or specified, used as a standard measurement of like kinds. ONE
  • CASnumber; A unique numerical identifier assigned, by the Chemical Abstract Service (CAS), a division of the American Chemical Society, to chemical compounds, polymers, biological sequences, mixtures, and alloys. ONE
  • molecularWeight; This is the molecular weight of the entity being described, not of the parent. Units should be included in the form. ONE
  • pH Quantity of dimension one used to express on a scale from 0 to 14 the amount-of-substance concentration of hydrogen ion of dilute aqueous solution, calculated as the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter. ONE

Example
{"ChemicalSubstance":

"CASnumber": "77-86-1"
}
]
}

Hi, thanks for opening the issue and get the discussion rolling. With @egonw and @meier-rene we recently discussed stuff around ChemicalSubstance.
Here are some (unsorted) thoughts:

Yours,
Steffen
