epdnorway 0.3

Extract and organize datapoints from Epd Norway DataSet

epdnorway

Python module (pypi.org) to consume XML data from https://digi.epd-norge.no/ into any python project.

Requirements

python v3.7 xmltodict (xmltodict-0.12.0)

Usage

pip install epdnorway

Example usage:

	from epdnorway import *
	import pprint as pp

query dataset and show a json list result

	res = epdnorway.list_query("limtre")
	pp.pprint(res)

get a specific dataset, e.g. first of results

	dataset = epdnorway.DataSet(res[0]["uuid"])

To get a list of available Exchange Flows:

	dataset.availableFlows()

Correspondingly, to get available Impact Assessments:

	dataset.availableImpactAssessments()

Data Points are now accessible as dataset.impactAssessments and dataset.exchangeFlows Entire dataset is accessible in dataset.data

Possible Datapoints

Handled Datapoints are to be found in the following constants:

	pp.pprint(epdnorway.EXCHANGE_FLOWS)
	pp.pprint(epdnorway.LIFE_CYCLE_METHODS)

Data Points are stored as keys, and values in secondary keys in amounts List possible amounts for modules:

pp.pprint(epdnorway.KNOWN_MODULES)

Get specific datapoints

Example: get the numbers for Global warming potential

	>>> gwp = dataset.getImpact("GWP")
	>>> gwp.data
	{'id': '77e416eb-a363-4258-a04e-171d843a6460', 'name': 'Global warming potential', 'meanAmount': '0.0', 'unit': 'kg CO2-Äqv.', 'amounts': {'A1-A3': -679.0}}

get the reference flow of the dataset

	>>> dataset.referenceFlow.data
	{'id': '5ba9fce9-252d-457d-aea8-45d7d4c9a17d', 'name': 'Limtre', 'meanAmount': '1.0', 'resultingAmount': '1.0', 'version': '00.01.000'}

and the units for reference flow (if any):

	>>> dataset.referenceFlow.units
	[{'name': 'bulk density', 'desc': 'kilograms per cubic metre', 'unit': 'kg/m^3', 'value': '430.0'}]
