  smiles_string:
    name: smiles_string
    description: A string encoding of a molecular graph, no chiral or isotopic information.
      There are usually a large number of valid SMILES which represent a given structure.
      For example, CCO, OCC and C(O)C all specify the structure of ethanol.
    title: smiles string
    comments:
    - a problematic set of structures to describe using SMILES notation is those which
      cannot be easily described using molecular graphs (see “Limitations of molecular
      graph representations” section), such as organometallic compounds and ionic
      salts.

      two different sub-properties of subclass of for two cases: (1) subtype_of, which
      connects grouping classes (e.g. alkane is_a hydrocarbon; alpha-amino-acid is_a
      amino-acid), (2) classified_by, which connects a specific element to a grouping
      class (e.g. methane is_a hydrocarbon; iron is_a metal; serine is_a amino-acid)'
