+# Document Batch Processing
+
+This directory contains the service layer for managing document batch uploads.
+
+## Purpose
+
+The batch service provides a business logic layer between the HTTP API handlers and the database repository for batch upload operations. It handles:
+
+- **Model Conversion**: Translates between OpenAPI-generated types and internal database models
+- **Business Logic**: Encapsulates batch-specific operations (CRUD, progress tracking)
+- **Data Validation**: Manages UUID conversions, JSONB parsing, and nullable type handling
+
+## Architecture
+
+```
+HTTP Request → API Handler → Batch Service → Database Repository → PostgreSQL
+```
+
+The service is **stateless** and **synchronous** - it does not run background processes. Actual document processing happens through the existing Runner pipeline (`storeEventRunner` → `docInitRunner` → etc.).
+
+## Files
+
+- `service.go` - Main batch service implementation with CRUD operations
+- `service_test.go` - Unit tests using testcontainers for database integration
+
+## Usage
+
+The service is instantiated by API handlers in `/api/queryAPI/documents.go` to manage batch upload metadata, progress tracking, and status updates.
