## OVERVIEW

This policy establishes the version control standards and procedures for all DBIS documentation. It ensures consistent versioning, change tracking, and document lifecycle management across all institutional documents.

---

## VERSION NUMBERING SCHEME

### Semantic Versioning (SemVer)

All DBIS documents shall use **Semantic Versioning** format: `MAJOR.MINOR.PATCH`

**Version Components:**
- **MAJOR (X.0.0):** Breaking changes, major revisions, or fundamental restructuring
  - Example: Complete rewrite of document structure
  - Example: Changes that invalidate previous interpretations
- **MINOR (X.Y.0):** New features, additions, or non-breaking changes
  - Example: Addition of new sections or chapters
  - Example: New procedures or guidelines
- **PATCH (X.Y.Z):** Bug fixes, corrections, minor updates, or clarifications
  - Example: Typo corrections
  - Example: Updated cross-references
  - Example: Clarification of ambiguous language

**Examples:**
- `1.0.0` - Initial version
- `1.1.0` - Added new section on compliance procedures
- `1.1.1` - Fixed typo in Section 3.2, corrected cross-reference
- `2.0.0` - Major restructuring of document organization

### Version Number Assignment

**Initial Version:**
- All new documents start at version `1.0.0`
- Version `1.0.0` indicates the document is complete and approved

**Version Updates:**
- Increment PATCH for minor corrections: `1.0.0` → `1.0.1`
- Increment MINOR for additions: `1.0.0` → `1.1.0`
- Increment MAJOR for major changes: `1.0.0` → `2.0.0`
- Reset lower numbers when incrementing higher: `1.2.3` → `2.0.0`

---

## DOCUMENT STATUS

### Status Definitions

**Draft:**
- Document is work in progress
- Not yet approved for use
- Subject to revision
- Not binding or authoritative

**Active:**
- Document is approved and in effect
- Current and authoritative version
- Binding on all relevant parties
- Supersedes all previous versions

**Superseded:**
- Document has been replaced by a newer version
- Retained for historical reference
- Not current or authoritative
- Clearly marked with supersession notice

**Archived:**
- Document is no longer in use
- Retained for historical or legal purposes
- Not current or authoritative
- Stored in archive location

### Status Transitions

1. **Draft → Active:** Upon approval by appropriate authority
2. **Active → Superseded:** When new version is approved
3. **Superseded → Archived:** After retention period (typically 7 years)
4. **Active → Archived:** When document is no longer needed

---

## REVISION HISTORY

### Revision History Requirements

All major documents (Constitutional, Statutory Code, Technical Specifications, Major Manuals) shall include a revision history section.

**Revision History Format:**

```markdown
## REVISION HISTORY

- Used for final testing and preparation
- Merged to main and develop when ready

**Hotfix Branches:**
- `hotfix/description` - Critical fixes
- Created from main branch
- Merged to main and develop
