Some problem of the ontology and property among individuals


I download the “onotolgy dev” and the “DBpedia Ontology instance types” files. However, I met a problem when I try to use python library “owlready2” to load the ontology. Then, what I found out is that there are two “Things” classes in ontology. Besides, there are classes and properties with same URI which will result in metaclass conflict in python and some other problems.

Meanwhile, I found out instances in “DBpedia Ontology instance types” file only have “rdf:type” relation. Do they have any other object property or data property relation? I want files like format in “.owl”, “.ttl” or “.nt”.

Hope someone could give me some suggestions. Thanks a lot.
