# DBRS Tagging Specification v1.0

**Status:** Stable  
**Scope:** DBRS Frontmatter, Indexing, UX & LLM Consumption  
**Applies to:** Websites, Knowledge Hubs, Intranets, DBRS Repositories

---

## 1. Purpose

The DBRS Tagging Specification defines how tags are used to ensure:

- deterministic discoverability
- strict non-hallucinating LLM behavior
- high-quality user experience (UX)
- verifiable and citable references

This specification intentionally separates **discoverability** from **interpretation**.

---

## 2. Core Principle

> **Meta-tags may explain meaning.  
> Textual tags must enable finding.**

DBRS does not infer relevance through semantic guessing.  
All primary tags must be explicitly grounded in the source text.

## 3. Tag Categories

### 3.1 Textual Tags (`tags`)

**Definition:**  
Textual tags are literal identifiers used for search, navigation, UX, and strict LLM grounding.

**Rules (hard):**

- Each tag MUST appear verbatim in the document
- Allowed locations:
  - title
  - headings (h1–h3)
  - body text
- No normalization
- No synonym generation
- Case-sensitive
- Punctuation-sensitive

**Purpose:**

- User search & navigation
- Deterministic LLM entry points
- Prevention of false negatives
- Trust-preserving UX

**Example:**

```yaml
tags:
  - IT Service+
  - Managed IT
  - Bestands-IT
