Kurra

A Python package of RDF data manipulation and data management functions that can be called from the command line or other software.

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

  • manipulate local RDF files
  • send commands to RDF databases "triplestores"
  • SPARQL query files or databases
  • SHACL validate or apply rules to RDF data

kurra is for convenience: the functions it provides are simple but kurra saves you having to reinvent wheels.

CLI app

kurra presents a Command Line Interface that can be used on Mac, Linux and Windows (WSL) command prompts.

Once you have installed kurra (see below), you can ask it to tell you what commands it supports by using the --help or just -h, command, e.g.:

kurra -h

which will return something like:

╭─ Options ─────────────────────────────────────────────────────────────────────────────────╮
│ --version             -v                                                                  │
│ --help                -h        Show this message and exit.                               │
╰───────────────────────────────────────────────────────────────────────────────────────────╯
╭─ Commands ────────────────────────────────────────────────────────────────────────────────╮
│ db       RDF database commands                                                            │
│ file     RDF file commands                                                                │
│ shacl    SHACL commands                                                                   │
│ sparql   SPARQL queries to local RDF files or a database                                  │
╰───────────────────────────────────────────────────────────────────────────────────────────╯

To find out more about the specific options within db, file, shacl & sparql, run the help command at the next level, like this:

kurra db -h

or

kurra file -h

etc. for shacl & sparql

To get further help for the particular commands. For db, you will see something like this:

 Usage: kurra db [OPTIONS] COMMAND [ARGS]...
                                
 RDF database commands
 
╭─ Options ─────────────────────────────────────────────────────────────────────╮

╭─ Commands ────────────────────────────────────────────────────────────────────╮

Installation

CLI App

The recommended way to manage and run Python CLI apps is to use the Python package uv which you will need to install first, see the uv installation instructions. then:

uv tool install kurra

Now you can invoke kurra anywhere in your terminal as long as ~/.local/bin is in your PATH.

See the uv documentation on installing tools for more information.

Library

You can also install kurra as a Python library for used of its functions in other applications

pip install kurra

Use the relevant command to add dependencies to your project if you are using a tool like uv, poetry, or conda.

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

from kurra.file import reformat, make_dataset, export_quads

Development

Install the Poetry project and its dependencies:

task install

Format code:

task format

Test:

task test

You can test the command like app while in development with:

uv tool kurra {COMMANDS}

With {COMMANDS} as per the usual kurra CLI.

Releasing

To build a new release:

  • format code: task format
  • pass tests: task test
  • update version in pyproject.toml
  • Git commit & push all updates
  • Git tag with release version
    • git tag 2.2.4
    • git push --tags
  • make GitHub release
    • this will trigger pypi.yml workflow to publish to PyPI
  • update version in pyproject.toml to next release alpha and push
    • with message 2.2.4 post release
