# Naming Standards & Validation Rules

A **Tag** is used to label and classify objects for easier search, grouping, and filtering. Tag names must follow standardized naming rules to maintain consistency and system compatibility.

#### Validation Rules

<table><thead><tr><th width="230.2000732421875">Property</th><th>Value</th></tr></thead><tbody><tr><td>Blank Allowed</td><td>No</td></tr><tr><td>Maximum Length</td><td>Not specified</td></tr><tr><td>Allowed Characters</td><td>Alphabets (A–Z, a–z), Numbers (0–9), Spaces</td></tr><tr><td>Start Character Rule</td><td>Name must start with an alphabet or number</td></tr><tr><td>Disallowed Characters</td><td>Dot (<code>.</code>), Comma (<code>,</code>), configured concatenation delimiter, and special characters such as <code>! @ # $ % ^ &#x26; * _ + : ; &#x3C; > ? / \ " '</code></td></tr><tr><td>Validation Notes</td><td>The system rejects names containing restricted special characters or names starting with special characters</td></tr></tbody></table>

#### Examples

**Valid Examples**

* Sensitive Data
* Finance Tag
* Customer Info
* DataQuality

**Invalid Examples**

* `Tag.Name` → Contains dot
* `Tag,Data` → Contains comma
* `Tag@Data` → Contains restricted special character
* `Tag#1` → Contains restricted symbol
* `#Tag` → Starts with a special character
* `@DataTag` → Starts with a special character

#### System Behavior on Validation Failure

* The system prevents saving the Tag.
* Validation error messages are displayed.
* Correct the name before proceeding.

#### Best Practices

* Keep tag names short and meaningful.
* Avoid unnecessary symbols and special characters.
* Use consistent naming conventions across tags.

## Master Tag

A Master Tag is a standardized tag used across the system to ensure consistent classification and tagging. Master Tag names must follow standardized naming rules to maintain consistency and system compatibility.

#### Validation Rules

<table><thead><tr><th width="234.99993896484375">Property</th><th>Value</th></tr></thead><tbody><tr><td>Blank Allowed</td><td>No</td></tr><tr><td>Maximum Length</td><td>Not specified</td></tr><tr><td>Allowed Characters</td><td>Alphabets (A–Z, a–z), Numbers (0–9), Spaces</td></tr><tr><td>Start Character Rule</td><td>Name must start with an alphabet or number</td></tr><tr><td>Disallowed Characters</td><td>Dot (<code>.</code>), Comma (<code>,</code>), configured concatenation delimiter, and special characters such as <code>! @ # $ % ^ &#x26; * _ + : ; &#x3C; > ? / \ " '</code></td></tr><tr><td>Validation Notes</td><td>The system rejects names containing restricted special characters or names starting with special characters</td></tr></tbody></table>

#### Examples

**Valid Examples**

* PII Data
* Confidential
* Internal Use
* DataSecurity

**Invalid Examples**

* `Tag.Name` → Contains dot
* `Confidential@Data` → Contains restricted special character
* `Tag,Master` → Contains comma
* `#PII` → Starts with a special character
* `@Confidential` → Starts with a special character

#### System Behavior on Validation Failure

* The system prevents saving the Master Tag.
* Validation error messages are displayed.
* Correct the name before proceeding.

#### Best Practices

* Use standardized and reusable names.
* Avoid duplicate or similar tags.
* Maintain consistent naming conventions across the system.
