# ViewData

### Purpose
This module defines the view/viewmodel contract pair for a "ViewData" feature within the DTS application. It follows the MVVM (Model-View-ViewModel) pattern by providing marker interfaces that extend base view and viewmodel abstractions, enabling the system to identify and bind ViewData components without imposing additional behavioral contracts.

### Public Interface

**`IViewDataView`** (interface, `DTS.Common.Interface` namespace)
- Inherits from: `IBaseView`
- Members: None (marker interface)

**`IViewDataViewModel`** (interface, `DTS.Common.Interface` namespace)
- Inherits from: `IBaseViewModel`
- Members: None (marker interface)

### Invariants
- Both interfaces must be implemented together in a matching View/ViewModel pair to maintain MVVM consistency.
- Implementations must satisfy the contracts of `IBaseView` and `IBaseViewModel` respectively (specific contracts not visible in this source).

### Dependencies
- **Depends on**: `DTS.Common.Base` (specifically `IBaseView` and `IBaseViewModel`)
- **Depended on by**: Cannot be determined from source alone (likely ViewData feature implementations and DI container registrations)

### Gotchas
- Neither interface defines any members beyond their base interfaces. Any ViewData-specific behavior must be defined in concrete implementations or other partial contracts not shown here.
