+# Rust-Analyzer Semantic Analysis Dataset
+
+This dataset contains comprehensive semantic analysis data extracted from the rust-analyzer codebase using our custom rust-analyzer integration. It captures the step-by-step processing phases that rust-analyzer performs when analyzing Rust code.
+
+## Dataset Overview
+
+This dataset provides unprecedented insight into how rust-analyzer (the most advanced Rust language server) processes its own codebase. It contains **500K+ records** across multiple semantic analysis phases.
+
+### What's Included
+
+- **Parsing Phase**: Syntax tree generation, tokenization, and parse error handling
+- **Name Resolution Phase**: Symbol binding, scope analysis, and import resolution  
+- **Type Inference Phase**: Type checking, inference decisions, and type error detection
+
+### Dataset Statistics
+
+- **Total Records**: ~533,000 semantic analysis events
+- **Source Files**: 1,307 Rust files from rust-analyzer codebase
+- **Data Size**: ~450MB in efficient Parquet format
+- **Processing Phases**: 3 major compiler phases captured
+
+## Dataset Structure
+
+Each record contains:
+
+- `id`: Unique identifier for the analysis event
+- `file_path`: Source file being analyzed
+- `line`, `column`: Location in source code
+- `phase`: Processing phase (parsing, name_resolution, type_inference)
+- `element_type`: Type of code element (function, struct, variable, etc.)
+- `element_name`: Name of the element (if applicable)
+- `syntax_data`: JSON-serialized syntax tree information
+- `symbol_data`: JSON-serialized symbol resolution data
+- `type_data`: JSON-serialized type inference information
+- `source_snippet`: The actual source code being analyzed
+- `context_before`/`context_after`: Surrounding code context
+- `processing_time_ms`: Time taken for analysis
+- `rust_version`, `analyzer_version`: Tool versions used
+
+## Use Cases
+
+### Machine Learning Applications
+- **Code completion models**: Train on parsing and name resolution patterns
+- **Type inference models**: Learn from rust-analyzer's type inference decisions
+- **Bug detection models**: Identify patterns in diagnostic data
+- **Code understanding models**: Learn semantic analysis patterns
+
+### Research Applications  
+- **Compiler optimization**: Analyze compilation patterns across large codebases
+- **Language design**: Study how developers use Rust language features
+- **IDE improvement**: Understand common semantic analysis patterns
+- **Static analysis**: Develop better code analysis tools
+
+### Educational Applications
+- **Rust learning**: Understand how code is processed step-by-step
+- **Compiler education**: Visualize semantic analysis phases
+- **Code analysis tutorials**: Interactive examples of language server internals
+
+## Data Quality
+
+- ✅ **Schema validated**: All records follow consistent structure
+- ✅ **Data integrity**: No corrupted or malformed records  
+- ✅ **Completeness**: All processed files represented
+- ✅ **Self-referential**: rust-analyzer analyzing its own codebase
+
+## Technical Details
+
+- **Format**: Parquet files for efficient storage and fast loading
+- **Compression**: Snappy compression for optimal performance
+- **Chunking**: Files split to stay under 10MB for Git LFS compatibility
+- **Schema**: Strongly typed with proper null handling
