Issue 72 - Getting Closure

Here is my quick attempt at summary of many of the issues raised in Issue 72:

Main Issue:

  *   DOM Events as opposed to or in addition to  subscriptions
  *   ondata versus subscribe
  *   on change versus subscribe

AdamC’s Summary of Main Issue:

  *   Dedicated handlers for each property
     *   vehicle.trip.onaveragespeedchange
  *
     *   I don’t believe this will work in the case of setting a specific signal. You would have to have separate attribute for set and onchange which would get confusing.
  *   Generic observers
     *   vehicle.trip.averageSpeed.onchange
  *
     *   May create lots of edge cases
  *   Specific observers
     *   vehicle.trip.averageSpeed.onaveragespeedchange
  *
     *   Dramatically increase the quantity of APIs on vehicle
  *   Existing pub sub
     *   Not considered web friendly
  *
     *   Inconsistent with other web technologies

Ancillary Issues:

  *   complexity of zone
  *   suffixing interfaces
  *   Vehicle versus Sensors
  *   Web socket or REST calls to expose vehicle data
  *   Units


Talk with you all tomorrow.
