主なユースケース

資材価格を取得する

integrator = OpenDataIntegrator(region="US")

# Get material price indices
result = integrator.fetch_data("material_prices", {
    "materials": ["concrete", "steel", "lumber"]
})

print(f"Fetched: {result.records_fetched} records")
for record in result.sample_data:
    print(f"  {record['material']}: index={record['current']}, trend={record['trend']}")

プロジェクトデータを拡充する

project = {
    "name": "Office Building",
    "materials": ["concrete", "steel", "glass"],
    "trades": ["carpenter", "electrician", "plumber"],
    "location": {"lat": 40.7128, "lon": -74.0060},
    "start_date": date(2024, 6, 1),
    "end_date": date(2024, 12, 31)
}

enriched = integrator.enrich_project_data(project)

print(f"Sources used: {enriched.sources_used}")
print(f"Confidence: {enriched.confidence:.0%}")
print(f"Material indices: {enriched.enrichments.get('material_price_indices')}")

気象リスクを評価する

risk = integrator.get_weather_risk(
    lat=40.7128,
    lon=-74.0060,
    start_date=date(2024, 6, 1),
    end_date=date(2024, 8, 31)
)

print(f"Risk Level: {risk['risk_level']}")
print(f"Rain Days: {risk['rain_days']}")

• セマンティックマッピングには ontology-mapper を使用します
• 指数を使った cost-prediction を使用します
• 工程計画には weather-impact-analysis を使用します
