Should scattered_molecular_aggregate be a defined class?

    What are the arguments for and against?

    well, initially it was more of a question. Do you see classes being asserted underneath it? For example would blood serum, eluate, cell supernatant, chemical solution all not be scattered_moleculat_aggregates?

    Blood serum and other wholes would not be scattered aggregates by the current definiton: A scattered molecular aggregate is a material entity that consists of all the molecules of a specific type that are located in some bounded region and which is part of a more massive material entity that has parts that are other such aggregates.

    The aggregate of water molecules in a sample of blood would be a scattered aggregate, as would the the aggregate of CO2 molecules in a bottle of air.

    ok, so I assumed water would be a scattered_molecular_aggregate. However from the last bit of the defintion "..part of a more massive material entity that has parts that are other such aggregates." water could not be defined like this, as it has only (assuming pure) an aggregate of H20 molecules, not "other aggregates". Is this the intention?

    Discussed on 2016-10-24 OBI call. No driving use cases so far. Nothing inferred under it when changed to defined class. So, we decide to close it.
