parsimony-snb 0.5.0

Swiss National Bank connector for the parsimony framework

parsimony-snb

Swiss National Bank connector plugin for parsimony — monetary, exchange-rate, balance-of-payments, and price series from the SNB data portal (https://data.snb.ch).

Part of the parsimony-connectors monorepo. Distributed standalone on PyPI as parsimony-snb.

Connectors

Name	Kind	Description
snb_fetch	connector	Fetch an SNB cube as a tidy DataFrame by cube_id, with optional date window, dimension selection, and language.
enumerate_snb	enumerator	Enumerate the curated SNB cube list with inferred category and frequency (drives the snb catalog).

Install

pip install parsimony-snb

Pulls in parsimony-core>=0.4,<0.5 automatically. Verify discovery:

python -c "from parsimony import discover; print([p.name for p in discover.iter_providers()])"

Quick start

import asyncio
from parsimony_snb import CONNECTORS

async def main():
    connectors = CONNECTORS.bind_env()
    result = await connectors["snb_fetch"](cube_id="rendoblim")
    print(result.data.head())

asyncio.run(main())

For multi-plugin composition:

from parsimony import discover
connectors = discover.load_all().bind_env()

Catalog publishing

This plugin publishes a catalog under the snb namespace, backed by enumerate_snb (param-less; probes a curated SNB cube list).

parsimony publish --provider snb --target "hf://<your-org>/parsimony-snb"

The {namespace} placeholder in --target is substituted with snb at publish time; targets support file://, hf://, and s3:// schemes.
