How to use

The package provides several backends implementations. After installing they are automatically available inside the tripper leveraging the entry-point system.

from tripper import Triplestore

ts = Triplestore(backend="fuseki", ...)

---

Backend specific details

Each backend may have its own configuration in the Triplestore class. This section provides usage examples for each of them

Stardog

from tripper import Triplestore

ts = Triplestore(backend = "stardog", 
                 base_iri = "http://example.com/myontology#", 
                 triplestore_url = "http://localhost:5820", 
                 database = "database",
                 uname = "some_username"
                 pwd = "some_pwd"
)

• base_iri: the base IRI to start with (if it is not defined)
• triplestore_url: the Stardog service endpoint
• database: the name of the database to use
• uname (optional): the username to log in
• pwd (optional): the password to log in

Fuseki

from tripper import Triplestore

ts = Triplestore(backend = "fuseki", 
                 base_iri = "http://example.com/myontology#", 
                 triplestore_url = "http://localhost:3030", 
                 database = "database"
