Python library for generating and parsing RFC 8141 compliant uniform resource names (URN).
To use this library in your project, install it with pip
pip install urnparseTo validate a given URN string against the RFC 8141 specification and construct
an URN object from it, use the URN8141.from_string() method:
from urnparse import URN8141
urn_string = 'urn:example:example.org:resources:'+\
'example%20resource?+res1=a'+\
'?=param1=test¶m2=test2#example.org'
urn = URN8141.from_string(urn_string)You can then access the specific URN components:
print(urn.namespace_id)
# example
print(urn.specific_string.decoded)
# example.org:resources:example resource
print(urn.specific_string.parts)
# ['example.org', 'resources', 'example resource']
print(urn.rqf_component.resolution)
# {'res1': 'a'}
print(urn.rqf_component.query)
# {'param1': 'test', 'param2': 'test2'}
print(urn.rqf_component.fragment)
# example.orgTo create an RFC 8141 formatted URN string for a certain resource, construct the URN object from the following components:
from urnparse import URN8141, NSIdentifier, NSSString, RQFComponent
nid = NSIdentifier('example')
nss = NSSString('example.org:resources:example%20resource', encoded=True)
rqf = RQFComponent(resolution_string='res1=a',
query_string='param1=test¶m2=test2',
fragment='example.org')
urn = URN8141(nid=nid, nss=nss, rqf=rqf)
print(urn)
# urn:example:example.org:resources:example%20resource?+res1=a?=param1=test¶m2=test2#example.org
