UN/CEFACT e-CMR - What it isn't




I was surprised to find that the one thing missing from the e-CMR specification is a digital CMR note. It made no sense to me. I hope you are puzzled too. I have spent months. Yes, months unravelling the published XSD message standard and have only just spotted this.


The UN/CEFACT approach and rigour they employ creating something like the e-CMR schema is a huge barrier to seeing and understanding the code. It's not just this one, the e-CMR, there are 100+ plus such specimens.


I am hoping this hard won "pearl of wisdom" will save you having to go through my pain.


Why isn't it there?


Here goes - what I think.


A paper CMR note does not fit in the UN/FACT digital world. There can be no such thing. In the rarified world of UML modelling it can not exist .... OK, it's also a multi-part paper form, but that would spoil the fun.


So why publish a UN/CEFACT e-CMR standard that doesn't have a paperless CMR?


The rationale is simple and I'm not saying it's right - but at the core of UN/CEFACT is "sending emails" as events happen - not to share documents.


Distinct data exchanges - not a single form with everything on it!! i.e. the same message with the same content passing back and fore being added to, it just doesn't fit.


The result is a recipe book of all the data and all the events you'd send emails about in the UN/CEFACT virtual reality of road haulage.


My thoughts. Is it a good thing the digital CMR note can't be found? "YES" Can you avoid a digital CMR note? "NO" Can you have a UN/CEFACT compliant digital CMR note? "YES".


Have a look if you don't believe me.
