MapManager Database Design - Discussion Summary
Project: RobotNet10.MapManager
Date: 2024-11-26
Participants: AI Assistant & DangNV
Topic: Database design for VDMA LIF 1.0.0 compliant map management system
Final Version: 2.0 (GUID-based naming)
📋 Overview
This document summarizes the complete discussion and design decisions for the RobotNet10.MapManager database schema, which manages AGV/AMR maps according to VDMA LIF (Layout Interchange Format) 1.0.0 standard.
FINAL IMPLEMENTATION: GUID 8-character based automatic naming system (optimized for Import/Export scenarios)
🎯 Project Goals
- VDMA LIF Compliance: 100% adherence to lif-schema.json specification
- Multi-Level Support: Handle buildings with multiple floors
- Version Control: Track layout changes over time
- VehicleType Customization: Per-vehicle properties for nodes and edges
- Scalability: Support up to 100k+ nodes and edges per level
- Import/Export Ready: Seamless VDMA LIF JSON import/export without conflicts
📚 Reference Documents
- VDMA LIF Schema:
lif-schema.json(provided by user) - VDMA LIF Specification:
FuI_Guideline_LIF_GB_final.pdf - Target Framework: .NET 10.0
- ORM: Entity Framework Core 9.0.0
- Database: SQLite (design-time), SQL Server (production)
🔍 Key Discussion Points & Evolution
1. Layout Hierarchy Structure
Decision: Option B - Hierarchy ✅
Layout (Building/Facility)
└── LayoutVersion (Version History)
└── LayoutLevel (Floor/Level)
├── Nodes
├── Edges
└── Stations
Rationale:
- Clear separation: Layout represents the facility, not a specific version
- Multiple versions per layout for history tracking
- Multiple levels per version for multi-floor buildings
- VDMA LIF export: layoutId is shared across all levels within a version
2. VehicleType Architecture
Decision: Separate VehicleTypes table as master data ✅
Structure:
VehicleTypes (Master data)
├── Used in: NodeVehicleProperties (junction table)
└── Used in: EdgeVehicleProperties (junction table)
Key Points:
- VehicleType = Robot type (e.g., AMR-T800, AMR-F100)
- One map can support multiple VehicleTypes
- Properties are vehicle-specific:
vehicleTypeNodeProperties: theta, actions (JSON)vehicleTypeEdgeProperties: orientation, speed limits, trajectory, etc.
- No physical specs (width, length) - focus on schema-defined properties only
3. Zones vs Stations
Initial: Zones concept was discussed
Final Decision: Use Stations per VDMA LIF schema ✅
Structure:
Stations
└── StationInteractionNodes (Many-to-Many with Nodes)
Rationale:
- VDMA LIF schema defines "stations" not "zones"
- Stations have interactionNodeIds array
- Represents loading/unloading points
4. Actions Storage
Decision: Store as JSON within vehicleType properties ✅
Not separate tables because:
- Actions structure varies by action type
- VDMA LIF defines actions as array within properties
- Flexibility for different action parameters
- Export/Import simplicity
Format:
{
"actions": [
{
"actionType": "pick",
"actionParameters": [...]
}
]
}
5. Layout Flags & Versioning
Layouts:
IsArchivedIsActive✅ Added - Indicates if layout is currently active
LayoutVersions:
IsActive✅ - Only ONE active version per layout- When active → READ-ONLY (cannot edit)
LayoutLevels:
LevelOrder✅ Kept - For flexible UI sorting (not tied to layoutLevelId)
6. Editor Settings - Major Design Evolution ⭐
This went through significant iteration:
Phase 1: Counter + Template Approach (Initial Design)
Proposed Fields:
LayoutLevelEditorSettings:
- EdgeCount (long)
- EdgeNameTemplate (string) e.g., "Edge_{0:D4}"
- NodeCount (long)
- NodeNameTemplate (string) e.g., "Node_{0:D4}"
- EdgeMinLengthCreate (double)
- EdgeNameAutoGenerate (bool)
- NodeNameAutoGenerate (bool)
- ImageWidth, ImageHeight (double?)
Pros:
- ✅ Human-readable: Node_0001, Node_0002
- ✅ Sortable chronologically
- ✅ Template flexibility
Cons:
- ❌ Import Problem: When importing VDMA LIF with existing nodes, counter conflicts occur
- ❌ Need atomic increment (complexity)
- ❌ 4 extra fields for counter state
- ❌ Template validation required
Phase 2: GUID-based Approach (Final) ✅✅✅
User Requirements:
- Large project expected (10k+ items per level)
- Import/Export is critical - counter causes conflicts
- Human-readability NOT important
- Sortability NOT needed
- Reference by name: nice to have but not critical
Analysis Performed:
- GUID 4 chars: ❌ 7% collision @ 100 items (too risky)
- GUID 6 chars: ⚠️ 3% collision @ 10k items (risky)
- GUID 8 chars: ✅ 0.0012% collision @ 10k items (safe with retry)
Final Decision: GUID 8 Characters ⭐
Simplified Fields:
LayoutLevelEditorSettings:
- EdgeNameAutoGenerate (bool)
- NodeNameAutoGenerate (bool)
- EdgeMinLengthCreate (double) - Meters
- OriginX (double) - Coordinate origin X in meters
- OriginY (double) - Coordinate origin Y in meters
- Resolution (double) - Meters per pixel (default: 0.05)
- BoundsMinX, BoundsMaxX (double?) - Coordinate bounds in meters
- BoundsMinY, BoundsMaxY (double?) - Coordinate bounds in meters
- ImageWidth (double?) - Pixels
- ImageHeight (double?) - Pixels
- CreatedDate, ModifiedDate (DateTime)
14 fields total (3 required coordinate fields + 4 optional bounds)
Name Format:
Node_a7f2e3b1 (8-char GUID)
Edge_3d8f9a2c (8-char GUID)
Benefits:
- ✅ Import-friendly: No counter conflicts
- ✅ Concurrent-safe: Parallel generation, no database locks
- ✅ Simpler: 4 fewer fields, no template validation
- ✅ Scalable: Safe up to 100k+ items with retry logic
- ✅ Fast: No atomic increment overhead
Collision Safety:
10,000 items: 0.0012% collision (1 in 83,000 cases)
50,000 items: 0.03% collision (1 in 3,000 cases)
100,000 items: 0.12% collision (1 in 800 cases)
With 2 retries: Practically zero collision
Service Implementation:
- Max 5 retries
- Logging for collision monitoring
- Exception if all retries fail (extremely unlikely)

🔄 Import/Export Logic
Export (Database → VDMA LIF JSON)
Input: LayoutId + LayoutVersion
Output: Single JSON file with all layoutLevelIds
Structure:
{
"metaInformation": {...},
"layouts": [
{
"layoutId": "warehouse_main",
"layoutVersion": "1.0",
"layoutLevelId": "floor_1",
"nodes": [...],
"edges": [...],
"stations": [...]
},
{
"layoutId": "warehouse_main",
"layoutVersion": "1.0",
"layoutLevelId": "floor_2",
...
}
]
}
Important: ❌ Do NOT export LayoutLevelEditorSettings (internal only)
Import (VDMA LIF JSON → Database)
1. Create/Update Layout (by layoutId)
2. Create/Update LayoutVersion (by layoutVersion)
3. For each layoutLevelId:
a. Create/Update LayoutLevel
b. Import Nodes (with GUID names if auto-generated)
c. Import Edges
d. Import Stations
e. Import VehicleType properties
4. Auto-create LayoutLevelEditorSettings with defaults
No counter conflicts - GUID-based names work seamlessly ✅
🗺️ Coordinate System Design ⭐
Overview
The MapManager uses a dual coordinate system approach to handle both physical world coordinates (for robot navigation) and image/screen coordinates (for UI rendering).
Coordinate Systems
1. World Coordinates (Physical Space)
- Unit: METERS (per VDMA LIF standard)
- Storage: All Nodes, Edges, Stations store X, Y in meters
- Origin: Defined by OriginX, OriginY in LayoutLevelEditorSettings
- Axis Convention:
- X-axis: Right (positive)
- Y-axis: Up (positive) - Mathematical/Engineering convention
- Used for: VDMA LIF data, robot navigation, path planning
2. Image Coordinates (Rendering Space)
- Unit: PIXELS
- Storage: ImageWidth, ImageHeight in LayoutLevelEditorSettings
- Origin: Top-left corner (standard image/screen convention)
- Axis Convention:
- X-axis: Right (positive)
- Y-axis: Down (positive) - Image/Screen convention
- Used for: Background image rendering, UI interactions
Coordinate Transformation
World → Image Pixel:
double imageX = (worldX - settings.OriginX) / settings.Resolution;
double imageY = (settings.ImageHeight ?? 0) - ((worldY - settings.OriginY) / settings.Resolution);
// Note: Y-axis is flipped (world Y-up vs image Y-down)
Image Pixel → World:
double worldX = (imageX * settings.Resolution) + settings.OriginX;
double worldY = ((settings.ImageHeight ?? 0) - imageY) * settings.Resolution + settings.OriginY;
LayoutLevelEditorSettings Coordinate Fields
| Field | Type | Default | Description |
|---|---|---|---|
| OriginX | double | 0.0 | World coordinate origin X in meters |
| OriginY | double | 0.0 | World coordinate origin Y in meters |
| Resolution | double | 0.05 | Meters per pixel (0.05 = 5cm per pixel) |
| BoundsMinX | double? | null | Minimum X boundary in meters (optional) |
| BoundsMaxX | double? | null | Maximum X boundary in meters (optional) |
| BoundsMinY | double? | null | Minimum Y boundary in meters (optional) |
| BoundsMaxY | double? | null | Maximum Y boundary in meters (optional) |
| ImageWidth | double? | null | Background image width in pixels |
| ImageHeight | double? | null | Background image height in pixels |
Resolution Examples
| Resolution | Meaning | Use Case |
|---|---|---|
| 0.01 | 1 pixel = 1 cm | High precision, small areas |
| 0.05 | 1 pixel = 5 cm | Default, balanced |
| 0.10 | 1 pixel = 10 cm | Large warehouses |
| 0.50 | 1 pixel = 50 cm | Very large outdoor areas |
Coordinate Bounds
Optional boundaries to constrain valid coordinates for a level:
Purpose:
- Prevent robots from being assigned invalid positions
- Define operational area limits
- Validate imported data
Example:
Warehouse Level 1:
- BoundsMinX: -10.0 meters (10m west of origin)
- BoundsMaxX: 100.0 meters (100m east of origin)
- BoundsMinY: -5.0 meters (5m south of origin)
- BoundsMaxY: 50.0 meters (50m north of origin)
- Total area: 110m × 55m = 6,050 square meters
Validation:
bool IsWithinBounds(double x, double y, LayoutLevelEditorSettings settings)
{
if (settings.BoundsMinX.HasValue && x < settings.BoundsMinX.Value) return false;
if (settings.BoundsMaxX.HasValue && x > settings.BoundsMaxX.Value) return false;
if (settings.BoundsMinY.HasValue && y < settings.BoundsMinY.Value) return false;
if (settings.BoundsMaxY.HasValue && y > settings.BoundsMaxY.Value) return false;
return true;
}
Design Rationale
| Decision | Rationale |
|---|---|
| Meters in database | VDMA LIF standard, robot navigation uses meters |
| Origin configurable | Different maps have different reference points |
| Resolution per level | Each floor may need different scale/precision |
| Y-axis flip in conversion | World (Y-up) vs Image (Y-down) standards |
| Optional bounds | Not always needed, flexibility |
| Part of EditorSettings | Coordinate mapping is UI/editor concern, not VDMA LIF data |
Import/Export Behavior
Export (Database → VDMA LIF):
- ✅ Export Node.X, Node.Y directly (already in meters)
- ✅ Export Station.X, Station.Y directly (already in meters)
- ❌ Do NOT export OriginX, OriginY, Resolution (editor-specific)
- ❌ Do NOT export Bounds (editor-specific)
Import (VDMA LIF → Database):
- ✅ Import coordinates directly to Node.X, Node.Y (meters)
- ✅ Use default Origin (0, 0) and Resolution (0.05)
- ✅ User can adjust Origin/Resolution after import for UI alignment
Common Scenarios
Scenario 1: New Map from Scratch
1. Create LayoutLevel
2. EditorSettings auto-created with defaults:
- OriginX = 0.0, OriginY = 0.0
- Resolution = 0.05 (5cm/pixel)
3. User places nodes → stored in meters from (0,0)
Scenario 2: Import Existing VDMA LIF
1. Import nodes with world coordinates (meters)
2. EditorSettings created with defaults
3. User uploads background image
4. User adjusts OriginX, OriginY to align image with nodes
5. User adjusts Resolution if scale doesn't match
Scenario 3: Large Warehouse
1. Import facility map (1000m × 500m)
2. Background image: 2000px × 1000px
3. Calculate Resolution: 1000m / 2000px = 0.5 m/pixel
4. Set OriginX = 0, OriginY = 0 (bottom-left corner)
5. Set Bounds: MinX=0, MaxX=1000, MinY=0, MaxY=500

🎓 Key Learnings
1. Import/Export First Design
- Original counter approach didn't account for import scenarios
- GUID approach solves this elegantly
- Design for data interchange, not just internal use
2. Simplicity Wins
- Removed 4 fields (templates + counters)
- Simpler is better when trade-offs are acceptable
- User confirmed human-readability not critical
3. Scale Appropriately
- 8-character GUID is sweet spot for this use case
- Not too short (high collision), not too long (unnecessary)
- Consider actual requirements, not theoretical extremes
4. VDMA LIF Extensions
- Clearly separate VDMA LIF data from UI extensions
- Document which fields are NOT exported
- Maintain 100% schema compliance where it matters
