A triplestore wrapper for Python.
Project description
Tripper
Triplestore wrapper for Python providing a simple and consistent interface to a range of triplestore backends.
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:
"http://emmo.info/emmo#Atom" -
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.
Documentation
- Getting started: See the tutorial
- Discovery of custom backends
- Reference manual
Installation
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
