Ruminating on Telematics standards

While creating training material for our internal staff on telematics, we found the below site that gives a very good introduction to novices on the basics of telematics -

I had covered the business benefits of telematics in this blog post. One of the fundamental challenge for the wide spread adoption of telematics has been the lack of standards around aggregating data from multiple TCU (Telematics Control Unit) vendors.

But now, the Association of Equipment Managers (AEM) and Association of Equipment Management Professionals (AEMP) have created a ISO standard to help systems
from different manufacturers all speak the same language - http://www.aemp.org/?page=AEMPTelematicsAPI

The AEMP 1.0 standard defined a XML data format that is available here.
An example of the AEMP REST API by John Deere is available here (in both XML and JSON formats) - https://developer.deere.com/content/documentation/aemptwo/fleet.htm#

The newer version (v 2.0) of the AEMP telematics standard is now an ISO standard (ISO 15143-3).
An example of ISO 15143-3 telematics API (with XML data format) is here.

As part of this standard, equipment makers would report the following data points and 42 fault codes using a standard protocol that will allow mixed equipment fleets to be managed from a single application.
