# GroupTemplates

## 1. Purpose  
This module defines two strongly-typed enumerations—`GroupTemplateChannelFields` and `GroupTemplateFields`—that represent the set of valid field names used when working with group templates and their associated channels in the DTS system. These enums serve as standardized identifiers for field-level operations (e.g., serialization, mapping, validation, or UI binding) related to group template data structures, ensuring consistency across layers that consume or produce group template metadata.

## 2. Public Interface  

### `GroupTemplateChannelFields`  
A `public enum` in namespace `DTS.Common.Enums.GroupTemplates` representing fields specific to a *channel* within a group template.  
- **Members**:  
  - `Required` (`int`): Indicates whether the channel is mandatory.  
  - `Name` (`int`): The display name of the channel.  
  - `ISOCode` (`int`): The ISO-standardized code associated with the channel (e.g., language or region code).  
  - `Custom` (`int`): A flag or value indicating the channel is user-defined/custom.  
  - `DisplayOrder` (`int`): The numeric order in which the channel should be rendered or processed.  

### `GroupTemplateFields`  
A `public enum` in namespace `DTS.Common.Enums.GroupTemplates` representing top-level fields of a *group template* entity.  
- **Members**:  
  - `Name` (`int`): The name of the group template.  
  - `Description` (`int`): A textual description of the group template’s purpose or behavior.  
  - `Channels` (`int`): A collection of channel definitions associated with the template.  
  - `LastModifiedBy` (`int`): Identifier (e.g., user ID or name) of the last modifier.  
  - `LastModified` (`int`): Timestamp of the last modification.  
  - `AssociatedGroups` (`int`): A collection of groups that are linked to this template.  

## 3. Invariants  
- All enum values are *exhaustive* for their respective domains (i.e., no additional fields are defined beyond those listed).  
- The `Channels` field in `GroupTemplateFields` is semantically a *container* for `GroupTemplateChannelFields`-defined properties, implying a hierarchical relationship: each channel object in a template’s `Channels` collection is described using keys from `GroupTemplateChannelFields`.  
- No runtime validation or enforcement logic is present in the source; enums are purely declarative and must be validated/consumed by other components.  

## 4. Dependencies  
- **Internal**:  
  - No external dependencies are referenced in the source files (no `using` statements, no references to other types).  
  - Both enums reside in the same namespace (`DTS.Common.Enums.GroupTemplates`), suggesting co-location for related functionality.  
- **Consumers**:  
  - Likely used by higher-level modules handling group template serialization (e.g., JSON/XML mapping), UI form generation, or data persistence layers (e.g., ORM mappings).  
  - Notable absence of direct references to `GroupTemplate` or `GroupTemplateChannel` classes in the source means their definitions (and usage of these enums) must be in other files.  

## 5. Gotchas  
- **Ambiguity in `Custom` and `Required` semantics**: The source does not clarify whether `Custom` is a boolean flag or a string/value field (e.g., custom metadata). Similarly, `Required` may represent a boolean, string, or enum—its meaning is inferred but not defined here.  
- **No versioning or deprecation markers**: The enums lack attributes (e.g., `[Obsolete]`) or comments indicating field lifecycle status, which could lead to misuse if fields are retired or renamed.  
- **No explicit mapping to database columns or JSON keys**: While the enum names suggest field identifiers, their actual serialization behavior (e.g., camelCase, underscore naming, or numeric values) is not specified in this module.  
- **None identified from source alone.**
