### Comprehensive Tagging System for Document Management

To create an effective tagging system, we will use established practices and focus on primary, secondary, tertiary, and contextual tags to ensure your documents are organized and easily searchable.

### Tagging Structure

#### Primary Tags
- High-level categories representing the main focus of the document.

#### Secondary Tags
- Subcategories providing more specific details about the document's content.

#### Tertiary Tags (Optional)
- Additional tags offering further granularity and context.

#### Contextual Tags (Optional)
- Tags for special context or unique identifiers (e.g., project names, specific events).

### Common Tags

**Personal:**
- **Primary:** `personal`
- **Secondary:** `habits`, `routines`, `goals`
- **Tertiary:** `morning`, `evening`, `health`

**Recipes:**
- **Primary:** `recipes`
- **Secondary:** `main_courses`, `desserts`, `beverages`, `appetizers`
- **Tertiary:** `baking`, `grilling`, `vegetarian`
- **Contextual:** `holiday_special`, `family_favorites`

**Travel:**
- **Primary:** `travel`
- **Secondary:** `guides`, `itineraries`, `destinations`, `activities`

**Knowledge:**

### Sample Front Matter

Here is a sample front matter for a document using the defined tagging structure:

#### Sample Document: Morning Routine

```markdown
---
title: "Morning Routine"
tags: ["personal", "habits", "routines", "morning"]
date: 2024-05-28
---
```

### Implementation Steps

1. **Understand the Content:**
   - Read through the document to understand its primary focus and key points.
   - Identify the main topics, subjects, and themes discussed in the document.

2. **Apply Primary Tags:**
   - Determine the high-level category that best represents the document.
   - Use one primary tag (e.g., `personal`, `recipes`).

3. **Add Secondary Tags:**
   - Provide more specific details about the content.
   - Use 1-2 secondary tags (e.g., `habits`, `routines`).

4. **Optional Tertiary Tags:**
   - Add further granularity if needed.
   - Use 1-2 tertiary tags (e.g., `morning`, `evening`).

5. **Optional Contextual Tags:**
   - Include special context or unique identifiers.
   - Use 1-2 contextual tags (e.g., `2024`, `routine_improvement`).

6. **Keep Tags Concise and Relevant:**
   - Avoid over-tagging; use only as many tags as necessary.
   - Ensure consistency in tag usage across similar documents.
