What is the infotable format in javascript?

Here is a sample of setting a property of a thing using SetPropertyValues.

var myInfoTable = { dataShape: { fieldDefinitions : {} }, rows: [] };

myInfoTable.dataShape.fieldDefinitions["safety"] = {

     name: "safety",

     baseType: "BOOLEAN"

};

myInfoTable.rows=[{safety:true}];

Things["AquaponicsThing"].SetPropertyValues({

  values: myInfoTable

});

This can be done much more easily within a service by just doing:

Things["AquaponicsThing"].safety = true;
