Basic concepts

Tripper provides a simple and consistent interface to a range of triplestore backends. It strives for simplicity and is modelled after rdflib (with a few simplifications).

In Tripper:

  • All IRIs are represented by Python strings. Example: ""

  • Blank nodes are strings starting with "_:". Example: "_:bnode1"

  • Literals are constructed with tripper.Literal. Example: tripper.Literal(3.14, datatype=XSD.float)

To make it easy to work with IRIs, provide Tripper a set of pre-defined namespaces, like XSD.float. New namespaces can be defined with the tripper.Namespace class.

A triplestore wrapper is created with the tripper.Triplestore class.

Advanced features

The submodules mappings and convert provide additional functionality beyond interfacing triplestore backends:

  • tripper.mappings: traverse mappings stored in the triplestore and find possible mapping routes.
  • tripper.convert: convert between RDF and other data representations.



Tripper has by itself no dependencies outside the standard library, but the triplestore backends may have specific dependencies.

The package can be installed from PyPI using pip:

pip install tripper
