MongoChem Schema

This page describes the schema for the mongo database used by ChemData.

Molecules Collection

The data is stored in a format similar to Chemical JSON.

{ 
  "name" : "phenol"
  "atomCount" : 13,
  "heavyAtomCount" : 7,
  "formula" : "C6H6O",
  "inchi" : "InChI=1S/C6H6O/c7-6-4-2-1-3-5-6/h1-5,7H",
  "inchikey" : "ISWSIDIOOBJBQZ-UHFFFAOYSA-N",
  "descriptors" : {
    "tpsa" : 20.2,
    "xlogp3" : 0,
    "mass" : 94.11,
    "rotatable-bonds" : 0,
    "vabc" : 89.95
  },
  "annotations" : {
      ["john", Date(), "ran test #4 on phenol"]
  },
  "diagram" : BinData(0, "...")
}

The data is indexed by inchikey (unique) and heavyAtomCount (non-unique).
