Class: Quantity

name: Quantity
description: A structured object to represent an amount of something (e.g., weight,
  mass, length, duration of time) - including a value and unit.
comments:
- QuantityMeasure may be implemented as an Observation-like object that will let us
  capture any type of measure of the amount of some substance (e.g. "weight", "volume"),
  with distinct timestamps and methods associated.  It could be implemented as a "simple"
  observation (one measurement per instance, where the "code" fields is bound to a
  value set describing the different types of quantity measures allowed -  e.g. "weight",
  "volume", "concentration"),  or as "composite" observation (multiple measurements
  possible in a single instance, each captured as a component defined to hold a specific
  type of quantity measure - e.g.  "weight", "volume", "concentration").  The number
  of different quantity measures we anticipate needed to support, and the potential
  for data sparseness, are factors that determine whether a simple or composite Observation
  would be most appropriate.

  id:

    description: The 'logical' identifier of the entity within the system of record.  The
      simple value of this attribute stands for an identifier of this data object
      within the system, it can be used as a reference from other objects within the
      same system (i.e. primary and foreign keys), and it should be unique per type
      of object. The same data object copied to a different system will likely have
      a different "id" in the new system since "id" values are system specific and
      do not represent persistent business identifiers. Business identifiers are assigned
      outside the information system and are captured in the "identifier" field. The
      "id" field is more likely to be a serially or randomly generated value that
      is assigned to the data object as it is created in a system.
