BCS Viewer

Purpose and scope of the BCS Viewer are to provide a rigorous, read-only view into Business Classification System datasets across regions. It enables auditors, data engineers, and compliance officers to verify code definitions, explore hierarchical relationships, and compare regional mappings without modifying source data. The tool is designed for governance workflows, crosswalk validation, and structured reporting.
\n\nCore capabilities include dataset loading, code lookup, hierarchical traversal, and region-aware crosswalks. Export options support CSV and JSON formats for downstream analytics. Advanced features include multi-region comparisons, versioned snapshots, fuzzy searches, and change detection to surface deviations between releases. The system enforces consistency rules such as valid parent-child links and crosswalk mappings to related standards.
\n\nInputs consist of dataset_id (string), region (string), optional query (string), and include_inactive (boolean). Outputs deliver a structured view with codes, identifiers, labels, region metadata, and relationship details. Results can be paginated for large datasets and exported for audits or governance reporting. The underlying algorithms emphasize deterministic behavior, reproducible exports, and robust handling of missing data.
