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 long-format DataFrame by cube_id — both publication cubes (rendoblim) and data-warehouse cubes (BSTA@SNB.AUR_U.ODF), routed automatically. Optional date window, dimension selection, and language.
enumerate_snb enumerator Enumerate every SNB cube discovered live from the portal sitemap (publication + warehouse) as catalog rows (drives the snb catalog).
snb_search search Semantic search over the published SNB catalog. Pass the returned cube_id column to snb_fetch(cube_id=...).

Coverage

The cube universe is discovered live from the SNB portal's published XML sitemap (https://data.snb.ch/sitemap), so the catalog self-tracks new cubes:

  • 237 publication cubes (/topics/{topic}/cube/{id}) — catalogued at series granularity (compound cube_id#series_key codes).
  • 912 data-warehouse cubes (/warehouse/{group}/cube/{sdmx_id}, groups BSTA / ZAST / ZAHL / DDUM / KRED / SNB1A / WKI) — catalogued at cube level; the individual dimension-leaf series stay fetchable via dim_sel.

Every catalogued cube (1,149 total) is fetchable through snb_fetch. Cube titles come from the portal's metadata API on a best-effort basis. SNB is a public, keyless data portal — no API key.

Install

pip install parsimony-snb

Pulls in a compatible parsimony automatically. Verify discovery:

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

Quick start

from parsimony_snb import CONNECTORS

result = CONNECTORS["snb_fetch"](cube_id="rendoblim")
print(result.raw.head())

For multi-plugin composition:

from parsimony import discover

connectors = discover.load_all()

Catalogs

snb_search runs semantic search over a published catalog snapshot (hf://parsimony-dev/snb by default; override with the PARSIMONY_SNB_CATALOG_URL env var or load(catalog_url=...)). The snapshot is built from enumerate_snb via scripts/build_catalog.py. No API key is required — SNB is a public, keyless data portal.
