# Documentation: DTS.Common.Interface (Viewer Module)

## 1. Purpose

This module defines the contract layer for the DTS Viewer application components, implementing a Model-View-ViewModel (MVVM) architecture with Prism modularity support. It provides interfaces for views, view models, and modules that enable loose coupling between UI components and their controllers. The interfaces support a tabbed document interface with dockable panels, diagnostic views, statistics displays, test management, and graph property editing capabilities.

## 2. Public Interface

### View Interfaces

All view interfaces inherit from `IBaseView` (defined in `DTS.Common.Base`) and are currently marker interfaces with no additional members:

| Interface | Purpose (inferred from naming) |
|-----------|-------------------------------|
| `ITabView` | Marker for tab container views |
| `IDiagView` | Marker for diagnostic views |
| `ITestsView` | Marker for test management views |
| `IStatsView` | Marker for statistics views |
| `ICursorView` | Marker for cursor-related views |
| `IViewerView` | Marker for main viewer views |
| `ITabItemView` | Marker for individual tab item views |
| `
