Project description

Build Status

WMO Core Metadata Profile Test Suite

This library implements validation against WMO Core Metadata Profile 1.3, specifically Part 2, Section 2.


python3 -m venv pywcmp
cd pywcmp
. bin/activate
git clone
cd pywcmp
pip3 install -r requirements.txt
python3 build
python3 install


From command line:

# fetch version
pywcmp --version

# abstract test suite

# validate metadata against abstract test suite (file on disk)
pywcmp ats validate --file /path/to/file.xml

# validate metadata against abstract test suite (URL)
pywcmp ats validate --url

# adjust debugging messages (CRITICAL, ERROR, WARNING, INFO, DEBUG) to stdout
pywcmp ats validate --url --verbosity DEBUG

# write results to logfile
pywcmp ats validate --url --verbosity DEBUG --logfile /tmp/foo.txt

# key performance indicators # note: running KPIs automatically runs the ats
pywcmp kpi validate --url --verbosity DEBUG

Using the API

# test a file on disk
>>> from lxml import etree
>>> from pywcmp.ats import ats
>>> exml = etree.parse('/path/to/file.xml')
>>> ts = ats.WMOCoreMetadataProfileTestSuite13(exml)
>>> ts.run_tests()  # raises ValueError error stack on exception
# test a URL
>>> from urllib2 import urlopen
>>> from StringIO import StringIO
>>> content = StringIO(urlopen('http://....').read())
>>> exml = etree.parse(content)
>>> ts = ats.WMOCoreMetadataProfileTestSuite13(exml)
>>> ts.run_tests()  # raises ValueError error stack on exception
# handle ats.TestSuiteError
# ats.TestSuiteError.errors is a list of errors
>>> try:
...    ts.run_tests()
... except ats.TestSuiteError as err:
...    print('\n'.join(err.errors))
>>> ...
>>> from pywcmp.kpi import WMOCoreMetadataProfileKeyPerformanceIndicators
>>> kpis = WMOCoreMetadataProfileKeyPerformanceIndicators(exml)
>>> kpis['totals']
