# Create catalog object
catalog = Catalog()
catalog.identifier = "http://example.com/catalogs/1"
catalog.title = {"en": "A dataset catalog"}
catalog.publisher = "https://example.com/publishers/1"

# Create a dataservice based on an openAPI-specification:
url = ("https://raw.githubusercontent.com/"
      "OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml"
     )
oas = yaml.safe_load(requests.get(url).text)
identifier = "http://example.com/dataservices/{id}"
oas_spec = OASDataService(url, oas, identifier)
#
# Add dataservices to catalog:
for dataservice in oas_spec.dataservices:
  catalog.services.append(dataservice)

# get dcat representation in turtle (default)
dcat = catalog.to_rdf()
print(dcat.decode())
