Triplestore Abstraction Library

This library provides a unified interface for interacting with various RDF and GeoSPARQL triplestore backends. It allows developers to write code that is agnostic to the underlying triplestore implementation.

Features

• Common API for multiple triplestore backends
• Easy integration and backend switching
• Support for basic CRUD operations on triples
• GeoSPARQL support when provided by the selected backend
• Extensible for new triplestore implementations

Supported Backends

The library provides a unified abstraction layer for multiple triplestores.
Currently supported backends (alphabetically):

• AllegroGraph
• Apache Jena
• Blazegraph
• GraphDB
• Oxigraph
• QLever
• RDF4J
• Virtuoso

Installation

You can install the library along with all supported backends using:

pip install rdf-triplestore
# or
pip install rdf-triplestore[all]
pip install triplestore[all]

Alternatively, you can install the library with a specific backend only:

pip install rdf-triplestore[<backend>]

For example:

pip install rdf-triplestore[oxigraph]

GeoSPARQL-related dependencies are optional and can be installed separately with:

pip install rdf-triplestore[geo]

Usage

from triplestore import Triplestore

# Initialize with desired backend
store = Triplestore(backend="jena", config={...})

# Load triples
store.load(data_filename)

# Add a triple
store.add(subject, predicate, obj)

# Query triples
results = store.query("SELECT ?s ?p ?o WHERE { ?s ?p ?o }")
