namespacelib 0.4.0

Utility library for the work with ontology namespaces.

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.
