namespacelib

Utility library for the work with ontology namespaces.

Usage

The namespaces interfaces implemented in this package allow to get the URI as a class property. Implementation similar to rdflib, which has implemented popular ontologies, like prov:

import rdflib

print(rdflib.PROV.Agent)
# rdflib.URIRef('http://www.w3.org/ns/prov#Agent')

Note, that you may access these namespaces also through namespaclib as it just "forwards" to rdflib.

Other namespaces, like M4I can be accessed like this:

import namespacelib

print(namespacelib.M4I.Tool)
# rdflib.URIRef('http://w3id.org/nfdi4ing/metadata4ing#Tool')

Very helpful for scientific data are the unit vocabulary qudt:

import namespacelib

print(namespacelib.QUDT_UNIT.M_PER_SEC)
# rdflib.URIRef('http://qudt.org/vocab/unit/M-PER-SEC')

print(namespacelib.QUDT_KIND.Velocity)
# rdflib.URIRef('http://qudt.org/vocab/quantitykind/Velocity')

An URI, that does not exist will raise an error (Other than rdflib, which can raise an AttributeError but does not by default!:

import namespacelib

# will raise an AttributeError:
print(namespacelib.QUDT_UNIT.METER)

Available namespaces:

• M4I
• OBO
• QUDT_UNIT
• QUDT_KIND
• CODEMETA
• SCHEMA

Limitations

Some vocabularies are not complete because names start with a digit, include a "#" or are called "yield", "True" or "False" (see schema.org, for example). These are not implemented in this package.
