Object Model for the Internet of Things

Here’s a first pass at an open source SCADA object model for the Internet of Things
The short story:
  • Devices are of a type, produce one or more Points (e.g. measurement), and are in a location.  These points are collected/pushed into a history on a periodic or demand basis. 
  • Each of these attributes can be virtual/calculated.
  • This model uses my standard lightweight metadata type system to avoid relying on a manufacturer/vendor-based structural standard.
  • It is intended for use with exabyte-quantity data stores
  • Some thought has been given to using IPv6 addresses as Point (and other entity) GUIDs
  • I release this design under the following license:
