# EdiDataElement

Domain entity representing Edi data element data within the edi area of the claims/policy domain, mapped for NHibernate persistence.*

## Purpose
- Models edi data element data used by the edi area of this library.*
- Inherits shared identity/lifecycle behavior from `EntityBase`.

## Context
- Namespace: `SAIF.Data.Model.Edi`
- Assembly/package: `SAIF.Data`

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| Id | `long Id { get; set; }` | Primary key / surrogate identifier for this record.* |
| Value | `string Value { get; set; }` | Value of value exposed by this type.* |
| Index | `int Index { get; set; }` | Value of index exposed by this type.* |
| CompositeIndex | `int CompositeIndex { get; set; }` | Value of composite index exposed by this type.* |
| IsComposite | `bool IsComposite { get; set; }` | Indicates whether composite.* |
| Segment | `EdiSegment Segment { get; set; }` | Reference to the associated `EdiSegment` record.* |

## Behavioral notes
- Properties are typically declared `virtual` to support NHibernate lazy-loading proxies (see the corresponding mapping file under `Data/SAIF.Data.NHibernate`).*

## Constraints and usage notes
- No additional usage constraints beyond standard NHibernate entity/DTO conventions could be confirmed from static analysis.**

> **Note:** Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
