# Lutece 8 Workflow Module Development

Complete guide for creating and modifying Lutece 8 workflow modules.

> Before writing workflow code, consult `~/.lutece-references/lutece-wf-module-workflow-forms/` (the reference module) using Read, Grep and Glob.

## Workflow Architecture

```
plugin-workflow (core)
├── library-workflow-core        # Base interfaces and classes
│   ├── ITask, Task, SimpleTask
│   ├── ITaskType, TaskType
│   ├── ITaskConfigService, TaskConfigService
│   └── ITaskConfigDAO
│
└── module-workflow-{xxx}        # Custom module
    ├── business/                # Config + DAO
    ├── service/                 # Task + Producers
    └── web/                     # TaskComponent
```

## Workflow Module Structure

```

## 1. Task Implementation

### Simple Task (no internal state)

```java
package fr.paris.lutece.plugins.workflow.modules.{pluginName}.service;

import fr.paris.lutece.plugins.workflowcore.service.task.SimpleTask;
import fr.pa
