cadis 0.8.160

Lat/Lon to administrative hierarchy lookup with managed datasets.

cadis

cadis is the single public control layer of the Cadis system.

It orchestrates:

• dataset install and bootstrap lifecycle
• world resolution and runtime execution coordination
• deterministic state to user-facing actions
• SDK + CLI + REST integration surfaces

Install

pip install cadis

Quick Start (CLI)

cadis lookup 41.8785708032352 12.505896501941912

Typical flow:

• If the country dataset is already installed, Cadis prints Region: ... immediately.
• If the dataset is missing but supported, Cadis offers to download it and retries the lookup after install.
• Sea and offshore results are shown directly in human-readable form.

Quick Start (SDK)

from cadis import CadisSDK

sdk = CadisSDK()
out = sdk.lookup(25.0330, 121.5654)
print(out["execution"]["lookup_status"])

Interaction Modes

• CLI guide: docs/cli.md
• SDK guide: docs/sdk.md
• Docker/REST guide: docs/rest.md
• Deployment guide: docs/deployment.md
• CI/CD examples: docs/cicd-examples.md
• Stable release manifest: releases/stable.json
• Stable manifest updater: scripts/update_stable_release_manifest.py

Core APIs

• lookup(lat, lon)
• lookup_many(points=[{"id": "...", "lat": ..., "lon": ...}])
• bootstrap(iso2, ...)
• reinstall(iso2, ...)
• info()
• CadisSDK
• CadisRemoteSDK

Dataset Lockdown

By default, Cadis serves lookups from any installed dataset in the cache folder.

To restrict serving to a subset of installed country datasets, set:

export CADIS_ALLOWED_ISO2=TW,JP

When enabled, Cadis fails lookups outside the allowlist with state.dataset.status = "blocked" and refuses bootstrap/reinstall for those countries.

Hierarchy Repair Model

Cadis treats dataset artifacts as read-only facts and performs lookup-time interpretation only. Polygon evidence remains the primary source for administrative hierarchy results.

When polygon evidence is missing an intermediate administrative level, Cadis may use the dataset hierarchy.json layer to complete the chain. Repair is capability-driven:

• Datasets with explicit branch identity metadata are repaired only when the candidate belongs to the same branch/path as the polygon evidence.
• Older datasets without branch identity metadata remain supported through the guarded legacy repair path.
• Name-based fallback is only used when no branch evidence can be established and the name resolves to exactly one feature in the dataset.

Cadis does not mutate datasets during repair. Invalid or cross-branch repair candidates are rejected instead of overriding polygon-derived evidence.

Architecture

cadis (public control layer)
  -> world resolution (`cadis.world`)
  -> dataset install/provisioning (`cadis.cdn`)
  -> dataset bootstrap/lookup runtime (`cadis.runtime`)
  -> deterministic structural engine (`cadis.core`)
  -> remote REST surface (`cadisd`)

ISO Code Policy

Cadis uses ISO 3166-1 alpha-2 codes as technical identifiers.

These codes are interpreted strictly according to the ISO 3166 standard and are used solely for data partitioning and administrative dataset selection.

Cadis does not interpret ISO codes as political statements or sovereignty declarations.

Additional ISO 3166-1 entity datasets will be published as they become available.

The us.admin dataset also covers supported U.S. territory extracts in the published source set. Cadis routes Puerto Rico (PR) and U.S. Virgin Islands (VI) lookups through the US dataset package.
