Get names of individuals

I would like to get the name of all of the instances of a given class, but without the URI prefix. I think this is more of an RDFLib specific issue dealing with URIRef objects, but maybe there’s a solution inside ontospy that I haven’t found yet

import ontospy
test_ontology_url = "http://www.w3.org/TR/2003/PR-owl-guide-20031209/wine"
ont = ontospy.Ontospy(test_ontology_url)
for clz in o.classes:
    print(clz)
    for instance in clz.instances():
        print(instance)
        print(dir(instance))

Output:

<Class *http://www.w3.org/TR/2003/PR-owl-guide-20031209/wine#AlsatianWine*>
<Class *http://www.w3.org/TR/2003/PR-owl-guide-20031209/wine#AmericanWine*>
<Class *http://www.w3.org/TR/2003/PR-owl-guide-20031209/wine#Anjou*>

['__add__', '__class__', '__contains__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__gt__', '__hash__', '__init__', '__invert__', '__iter__', '__le__', '__len__', '__lt__', '__mod__', '__module__', '__mul__', '__ne__', '__neg__', '__new__', '__or__', '__radd__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__sizeof__', '__slots__', '__str__', '__subclasshook__', '__truediv__', 'capitalize', 'casefold', 'center', 'count', 'de_skolemize', 'defrag', 'encode', 'endswith', 'eq', 'expandtabs', 'find', 'format', 'format_map', 'index', 'isalnum', 'isalpha', 'isdecimal', 'isdigit', 'isidentifier', 'islower', 'isnumeric', 'isprintable', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'maketrans', 'md5_term_hash', 'n3', 'neq', 'partition', 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'toPython', 'translate', 'upper', 'zfill']

...

None of the functions listed with dir return what I want (I iterated through all them and ran them) What I’d like is simply a way to retrieve:

And make it a bit more general than splitting on the # character, since not all ontologies have to use a # to differentiate the base IRI and the members, correct? Thanks so much for the help!

Ok I’ll try to add that with the next release.

Added with v1.8.8. Sorry it’s taken so long! You can now do this:

for instance in class.instances:
    print instance.uri, instance.qname

Note: instances are extracted on demand (once the method is called) so to avoid unnecessary calculations due to metaclasses and the same object being at the same time an instance and a class.
