🚀 Semantic Data Science Toolkit

Stop breaking pipelines when schemas change. The Semantic Data Science Toolkit introduces Stable Column Anchors (SCAs) that survive renames, reordering, and schema evolution.

✨ Key Features

• Stable Column Anchors: Schema resilience by design
• Intelligent Inference: 85%+ accuracy on automatic semantic detection
• Federated CID Registry: No central coordination required
• Performance-First: 1M+ rows/second processing
• SQL Generation: Export to Snowflake, BigQuery, DuckDB, and more

🎯 Quick Start (< 5 minutes)

npm install -g @semantic-ds/toolkit

# Run interactive quickstart
semantic-ds quickstart

# Or jump straight in
semantic-ds infer data.csv
semantic-ds generate-sql --target snowflake

API Overview

• Core Anchors: StableColumnAnchorSystem (fingerprinting, reconciliation)
• Persistence: YAML store under ./semantics/anchors/
• CLI: semantic-ds with init, infer, health, validate
