Introduction

This is a Node.js libary to parse EPCIS documents. We try to translate it into a more useful javascript structure.

Currently ObjectEvent and AggregationEvent are implemented.

Required or Optional

Fields	ObjectEvent	AggregationEvent	TransactionEvent	TransformationEvent
eventTime	R	R	R	R
recordTime	O	O	O	O
eventTimeZoneOffset	R	R	R	R
sourceList	O	O	O	O
destinationList	O	O	O	O
bizStep	O	O	O	O
disposition	O	O	O	O
readPoint	O	O	O	O
bizLocation	O	O	O	O
bizTransactionList	O	O	R	O
action	R	R	R
epcList	O		O
quantityList	O		O
childQuantityList		O
parentID		O	O
childEPCs		O
ilmd	O			O
inputEPCList				O
outputEPCList				O
inputQuantityList				O
outputQuantityList				O
transformationID				O

TODO

epcList: If multiple items are listet, the event is valid for all of them. Thus, it can be split into individual events too.
If bizTransactionList is given, it maps to the objects identified in epcList and quantityList. This means we could still create individual events here. Right?

_	Retrospective ( at the time of the event)	Prospective (true until contradicted by subsequent event)
What	EPC, EPCClass + quantity
When	Time
Where	ReadPointID	BusinessLocationID
Why	BusinessStepID	DispositionID
BusinessTransactionList, Source/Destination, ILMD

The implementation is based on Typescript. To start development run:

npm install     # installs the dependencies
grunt           # runs the tsc compiler

This will watch the .ts files and compile them into .js files

mocha tests/test_aggregation.js

mocha --debug-brk tests/test_aggregation.js

Then attach a debugger, e.g. Visual Studio Code.
