# D4D Metadata Extraction Status

**Date**: 2025-11-08
**Status**: In Progress

## Overview

This document tracks the status of D4D (Datasheets for Datasets) metadata extraction using two distinct approaches as documented in README.md.

## Approach 1: Automated LLM API Agents 🤖

### Individual File Processing

#### Validated D4D Wrapper (RECOMMENDED - COMPLETE)
- **Location**: `data/extracted_by_column_enhanced/`
- **Status**: ✅ Complete (Oct 31, 2025)
- **Input**: `downloads_by_column_enhanced/` (90 files)
- **Generator**: validated_d4d_wrapper.py (GPT-5)
- **Results**: 36+ D4D YAML files across 4 projects
  - AI_READI: 5 files
  - CHORUS: 2 files
  - CM4AI: 12 files
  - VOICE: 20 files
- **Reports**:
  - `validated_d4d_processing_report.md`
  - `validated_d4d_processing_summary.json`

#### D4D Agent Wrapper (IN PROGRESS)
- **Location**: `data/extracted_d4d_agent/enhanced/`
- **Status**: ⏳ Running (started Nov 8, 19:12)
- **Input**: `downloads_by_column_enhanced/` (84 files)
- **Generator**: d4d_agent_wrapper.py (OpenAI)
- **Progress**: 14/84 files (17%)
- **PID**: 33808

#### Legacy Results (ARCHIVED)
- `data/extracted_by_column/` - Earlier run (Oct 16-30)
- `data/extracted_by_column_previous_run/` - Sept 8 run

### Concatenated File Processing

#### Approach 1: Concatenated Processing (COMPLETE)
- **Location**: `data/sheets_concatenated/`
- **Status**: ✅ Complete (Oct 28, 2025)
- **Method**: Concatenate all D4D files → process with D4D agent
- **Generator**: aurelian D4D agent (GPT-5)
- **Results**: 4 comprehensive D4D YAML files
  - `AI_READI_d4d_alldocs.yaml` (9.0K)
  - `CHORUS_d4d_alldocs.yaml` (805B)
  - `CM4AI_d4d_alldocs.yaml` (1.9K)
  - `VOICE_d4d_alldocs.yaml` (12K)
- **Concatenated inputs**:
  - `AI_READI_concatenated.txt` (18K)
  - `CHORUS_concatenated.txt` (4.0K)
  - `CM4AI_concatenated.txt` (6.4K)
  - `VOICE_concatenated.txt` (19K)

## Approach 2: Interactive Coding Agents 👨‍💻

### Individual File Processing

#### Status: ❌ INCOMPLETE
- **Location**: Should be `data/extracted_claude_code/enhanced/`
- **Current scattered results**:
  - `data/claude_max_extractions/` - Partial (Sept 8, 10 files)
  - `data/extracted_coding_agent/` - Partial
- **Needed**: Generate complete set matching Approach 1 inputs
- **Method**: Claude Code interactive extraction with human oversight

### Concatenated File Processing

#### Status: ❌ INCOMPLETE
- **Location**: Should be `data/extracted_claude_code/concatenated/`
- **Needed**: Process concatenated files from `data/sheets_concatenated/`
- **Method**: Claude Code interactive synthesis

## Required Actions

### 1. Complete Approach 1 ✓ (Nearly Done)
- [x] Individual files - validated wrapper complete
- [⏳] Individual files - D4D agent wrapper running (17% done)
- [x] Concatenated files - complete

### 2. Generate Complete Approach 2 Results
- [ ] Create directory structure: `data/extracted_claude_code/`
  - `enhanced/` - Individual file extractions
  - `concatenated/` - Concatenated file extractions
- [ ] Generate D4D metadata for individual files using Claude Code
- [ ] Generate D4D metadata for concatenated files using Claude Code
- [ ] Include generation metadata headers documenting:
  - Generator: Claude Code (claude-sonnet-4-5)
  - Method: Interactive extraction with human oversight
  - Reviewer/validator information

### 3. Create Comparison Documentation
- [ ] Document differences in quality/completeness
- [ ] Highlight strengths of each approach
- [ ] Provide recommendations for future use

```

## Input Files

- **downloads_by_column/**: 22 files (original set)
- **downloads_by_column_enhanced/**: 90 files (enhanced with tabs/additional pages)

## Notes

- Approach 1 uses automated batch processing with minimal human intervention
- Approach 2 uses interactive coding agents (Claude Code) with human oversight
- Both approaches should generate results from same input sets for comparison
- Results should include generation metadata in YAML headers
