How to create our own classes and object Properties using RDFLIB python?

[manojms...@gmail.com]

I want to create below tripples using RDFLIB in python and add it to apache jena database. I am not exactly getting how can I create classes and peoperties using RDFLIB. Please let me know regarding this.

```

State a rdfs:Class .

:City a rdfs:Class .

:locatedIn a rdf:Property .

:capitalOf rdfs:subPropertyOf :locatedIn . 

:capitalOf rdfs:domain :City .

:capitalOf rdfs:range :State .

```

and also for this

```

Example:UsedCarForSale    RDF:type    RDF:Class

Example:Price RDF:type RDFS:Property

Example:PastOwners RDF:Type RDFS:Property

```

See this code within an API of mine that generated RDF from content in a Postgres DB:

https://github.com/CSIRO-enviro-informatics/gnaf-dataset/blob/master/model/address.py#L716

You can see an rdflib in-memory graph is created (‘g’) and then Namespaces for it are declared and bound to it. Triples are then added to that graph using g.add(()).

To get and RDF file from the in-memory graph, just do g.serialize(format=‘turtle’) or whatever format you like.
