Introduction

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

Impelementation Status

Currently ObjectEvent and AggregationEvent are implemented.

EPCIS Version 1.1 Specification (May 2014)

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

Different meanings of an "Action"

TODO

Notes

• 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?

General

_ | 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

Development

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

Tests

mocha tests/test_aggregation.js

Debugging

mocha --debug-brk tests/test_aggregation.js

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