Provium

Provium is a small standalone Python package for typed binary artifacts with automatic provenance.

Provium artifact files use the .pa extension.

Artifact I/O occurs only inside a scoped procedure execution. Every artifact opened in that scope is tracked automatically as an input, and every artifact created in that scope is tracked automatically as an output. Users do not construct or supply lineage manually.

Status

Provium is in pre-alpha development. Implementation follows the test-driven sequence in provium_tdd_plan.md, with each step reviewed before the next begins.

Development setup

Provium requires Python 3.12 or newer and has no required runtime dependencies.

python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -e '.[test]'

Run the test suite with:

pytest

The project configuration requires 100% statement and branch coverage for the provium package.

Planned API

from provium import Procedure

ADD = Procedure(name="add", version="1")

with ADD.execute():
    left = Integer.open("left.pa")
    right = Integer.open("right.pa")
    result = Integer.create("sum.pa")
    result.write(left.read() + right.read())

The API shown above is the target design and is not implemented yet.
