Hi all,
I'm a new-to-owlready2 user trying to load an ontology; unfortuantely owlready2 doesn't seem capable of following redirects for imports.
See this example in `Debt.rdf`, from
https://github.com/edmcouncil/fibo/blob/master/FBC/DebtAndEquities/Debt.rdf#L4````
<!ENTITY fibo-be-le-lp "
https://spec.edmcouncil.org/fibo/ontology/BE/LegalEntities/LegalPersons/">
````
In this case, the above redirects to another URL (can be seen with a wget):
wget
https://spec.edmcouncil.org/fibo/ontology/master/latest/BE/LegalEntities/LegalPersons/... redirects to
https://spec.edmcouncil.org/fibo/ontology/master/latest/BE/LegalEntities/LegalPersons.rdfIf I try to load this ontology:
Code to reproduce:
```
from owlready2 import *
o = get_ontology('
https://spec.edmcouncil.org/fibo/ontology/master/latest/FBC/DebtAndEquities/Debt/Debt')
o.load()
```
Then I get:
withproxy python test_owlready2.py
* Owlready2 * Warning: optimized Cython parser module 'owlready2_optimized' is not available, defaulting to slower Python implementation

https://spec.edmcouncil.org/fibo/ontology/master/latest/BE/LegalEntities/LegalPersons'!Possible cause:
- the the absence of "/" on the redirected URL (if you notice the stack trace's last line, the URL is missing the slash), this can be seen in
https://github.com/pwin/owlready2/blob/master/namespace.py#L1157NOTE: This issue was originally documented here :
https://github.com/edmcouncil/fibo/issues/1847 but determined not to be an issue with FIBO.
Let me know if you have any ideas!
