kurra 0.6.2

A Python library of common code and CLI apps shared across Kurrawong projects and infrastructure.

Kurra Python Library

A Python library of RDF data manipulation functions.

This library uses the RDFLib under-the-hood to process RDF data and supplies functions to:

• upload it to RDF databases - "triplestores" - and query them
• manipulate it in a few commands - e.g. format conversion

This toolkit provides a command line interface (CLI) for doing all of this as well as presenting its functions in a library that other Python applications can use.

Command Line Interface

kurra uses a Command Line Interface that can be inspected. Once you have installed kurra (see below), you can ask it to tell you want commands it supports with --help, e.g.:

kurra --help

which will return something like:

╭─ Options ───────────────────────────────────────────────────────────────────────────────────────────────────────╮ │ --install-completion Install completion for the current shell. │ │ --show-completion Show completion for the current shell, to copy it or customize the installation. │ │ --help Show this message and exit. │ ╰─────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯ ╭─ Commands ──────────────────────────────────────────────────────────────────────────────────────────────────────╮ │ list Get a list of Fuseki datasets │ │ create Create a new Fuseki dataset │ │ query Query a Fuseki database │ │ upload Upload files to a Fuseki dataset. │ │ format Format RDF files using one of several common RDF formats. │ │ version Show the version of the kurra app. │ ╰─────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯

You can then run

kurra format --help

or

kurra create --help

etc. to get further help for the particular commands.

Installation

For use as a Python library, simple installation from PIP/Poetry:

pip install kurra

poetry add kurra

Then import it and use in your code, e.g. for the format functions:

from kurra.format import format_file, make_dataset, export_quads
