dvcrn Open Data Integrator
Overview
Based on DDC methodology (Chapter 2.2), this skill integrates open construction datasets from various sources like government databases, industry benchmarks, weather services, and geospatial data.

Next Steps
- Use ontology-mapper for semantic mapping
- Use cost-prediction with indices
- Use weather-impact-analysis for scheduling
