Build the application

## Build
Inspect Industry Foundation Classes models against the buildingSMART Data Dictionary standard. Verify mandatory classification references and provide gap reports for architectural submittals.

## User
BIM procurement coordinator

## Workflow
1. Ingest IFC property records and component classification references.
2. Query mock bSDD endpoints using classification code keys.
3. Compare model classifications against required project standards.
4. Render compliance audit cards highlighting unclassified assets.

## Interface
Web portal showing classification trees, matched dictionary terms, and missing requirement alerts.

## Data
Utilize sample bSDD dictionary responses available in open bSDD documentation or create local JSON mocks.
Starter examples below are synthetic. They are not downloaded records.

## Source
[IfcOpenShell](https://raw.githubusercontent.com/IfcOpenShell/IfcOpenShell/v0.8.0/README.md)
Leverages the bsdd library specification in IfcOpenShell to query classification references against data dictionaries.

## Tools
dspy, fastapi.
DSPy compiles robust prompt pipelines that accurately map arbitrary IFC classification text to standardized bSDD keys.
Local or cloud LLM supported by DSPy for semantic classification matching.

## Deliverables
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

## Acceptance
- Matches IFC element classifications to simulated bSDD dictionary URIs.
- Identifies elements lacking required standard classification codes.
- Generates non-blocking warnings for unmapped custom properties.

## Safety
Read-only inspection of model metadata; no direct modification of original IFC files.
Use mock external writes. Require human review before any real deployment.
