# DSS Export/Import Implementation - Complete Summary
|
||||
|
||||
## 🎉 Project Complete
|
||||
|
||||
Full export/import system for DSS (Design System Studio) has been implemented with all 5 phases complete and production-ready.
|
||||
|
||||
---
|
||||
|
||||
## ✅ What Was Delivered
|
||||
|
||||
### Phase 1: Model Extensions (UUID Foundation)
|
||||
**Status**: ✅ COMPLETE
|
||||
|
||||
- Added `uuid` fields to all models:
|
||||
- `Project` → `uuid: str` (auto-generated)
|
||||
- `Theme` → `uuid: str` (auto-generated)
|
||||
- `DesignToken` → `uuid: str` + metadata (source, deprecated, timestamps)
|
||||
- `Component` → `uuid: str`
|
||||
- `ComponentVariant` → `uuid: str`
|
||||
|
||||
- Extended `DesignToken` with complete metadata:
|
||||
- `source`: Attribution (e.g., "figma:abc123")
|
||||
- `deprecated`: Deprecation flag
|
||||
- `created_at`, `updated_at`: Timestamps
|
||||
- All backward compatible (no breaking changes)
|
||||
|
||||
- Updated database schema:
|
||||
- Added `uuid TEXT UNIQUE` columns to `projects`, `components`, `styles`
|
||||
- Nullable columns for backward compatibility
|
||||
- Indexed for fast lookups
|
||||
|
||||
**Files Modified**:
|
||||
- `/dss-mvp1/dss/models/project.py`
|
||||
- `/dss-mvp1/dss/models/theme.py`
|
||||
- `/dss-mvp1/dss/models/component.py`
|
||||
- `/dss-mvp1/dss/storage/database.py`
|
||||
|
||||

|
||||
|
||||
### Phase 2: Archive Export System
|
||||
**Status**: ✅ COMPLETE
|
||||
|
||||
**Created**: `dss/export_import/exporter.py`
|
||||
|
||||
Implements complete project export to versioned `.dss` archive files:
|
||||
|
||||
**Key Classes**:
|
||||
- `DSSArchiveExporter`: Main export orchestrator
|
||||
- `DSSArchiveManifest`: Archive metadata and structure
|
||||
- `ArchiveWriter`: Low-level ZIP utilities
|
||||
|
||||
**Features**:
|
||||
- ✅ Creates `.dss` files (ZIP archives)
|
||||
- ✅ Exports all tokens with complete metadata (W3C-compatible)
|
||||
- ✅ Exports all components with variants and dependencies
|
||||
- ✅ Exports themes with cascade relationships
|
||||
- ✅ Exports project configuration
|
||||
- ✅ Manifest with schema versioning
|
||||
- ✅ Complete round-trip fidelity
|
||||
|
||||
**Archive Structure**:
|
||||
```
|
||||
project.dss (ZIP)
|
||||
├── manifest.json # Metadata, versions, contents summary
|
||||
├── config.json # Project configuration
|
||||
├── tokens.json # All tokens with metadata
|
||||
├── components.json # Components with props and dependencies
|
||||
└── themes.json # Theme definitions
|
||||
```
|
||||
|
||||
**Example**:
|
||||
```python
|
||||
from dss.export_import import DSSArchiveExporter
|
||||
exporter = DSSArchiveExporter(project)
|
||||
path = exporter.export_to_file(Path("my-design-system.dss"))
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 3: Archive Import System
|
||||
**Status**: ✅ COMPLETE
|
||||
|
||||
**Created**: `dss/export_import/importer.py`
|
||||
|
||||
Implements archive loading with comprehensive validation:
|
||||
|
||||
**Key Classes**:
|
||||
- `DSSArchiveImporter`: Main import orchestrator
|
||||
- `ArchiveValidator`: Multi-stage validation pipeline
|
||||
- `ImportAnalysis`: Pre-import analysis results
|
||||
- `ImportValidationError`: Detailed error information
|
||||
|
||||
**Validation Stages**:
|
||||
1. ✅ Archive integrity (valid ZIP, required files)
|
||||
2. ✅ Manifest validation (required fields, version format)
|
||||
3. ✅ Schema version compatibility (auto-migration support)
|
||||
4. ✅ Structural validation (JSON format, required keys)
|
||||
5. ✅ Referential integrity (all UUID refs resolve)
|
||||
|
||||
**Import Strategies**:
|
||||
- ✅ `REPLACE`: Full project restoration (backup/clone)
|
||||
- ✅ Analysis-only mode (preview without modifying)
|
||||
|
||||
**Example**:
|
||||
```python
|
||||
from dss.export_import import DSSArchiveImporter
|
||||
|
||||
importer = DSSArchiveImporter(Path("backup.dss"))
|
||||
analysis = importer.analyze() # Validate without import
|
||||
|
||||
if analysis.is_valid:
|
||||
project = importer.import_replace() # Full restore
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 4: Smart Merge System
|
||||
**Status**: ✅ COMPLETE
|
||||
|
||||
**Created**: `dss/export_import/merger.py`
|
||||
|
||||
Implements UUID-based intelligent merging with conflict detection:
|
||||
|
||||
**Key Classes**:
|
||||
- `SmartMerger`: Core merge orchestrator
|
||||
- `ConflictItem`: Detected conflict representation
|
||||
- `MergeAnalysis`: Merge operation analysis
|
||||
- `UUIDHashMap`: Content hash generation and comparison
|
||||
- `ConflictResolutionMode`: Strategy enum
|
||||
|
||||
**Merge Strategies**:
|
||||
- ✅ `OVERWRITE`: Import wins (timestamp-guided)
|
||||
- ✅ `KEEP_LOCAL`: Local version wins (safest)
|
||||
- ✅ `FORK`: Create duplicate with new UUID (no data loss)
|
||||
|
||||
**Merge Operations**:
|
||||
- ✅ `analyze_merge()`: Preview changes without modifying
|
||||
- ✅ `merge_with_strategy()`: Apply merge with chosen strategy
|
||||
- ✅ Conflict detection: Content hash-based
|
||||
- ✅ Conflict resolution: Multiple strategies
|
||||
|
||||
**Example**:
|
||||
```python
|
||||
from dss.export_import import DSSArchiveImporter
|
||||
from dss.export_import.merger import SmartMerger, ConflictResolutionMode
|
||||
|
||||
local_project = Project(...)
|
||||
importer = DSSArchiveImporter(Path("updates.dss"))
|
||||
imported = importer.import_replace()
|
||||
|
||||
merger = SmartMerger(local_project, imported)
|
||||
analysis = merger.analyze_merge()
|
||||
|
||||
merged = merger.merge_with_strategy(
|
||||
ConflictResolutionMode.KEEP_LOCAL
|
||||
)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 5: Schema Versioning & Migrations
|
||||
**Status**: ✅ COMPLETE
|
||||
|
||||
**Created**: `dss/export_import/migrations.py`
|
||||
|
||||
Implements schema evolution and backward compatibility:
|
||||
|
||||
**Key Classes**:
|
||||
- `MigrationManager`: Orchestrates migrations
|
||||
- `SchemaMigration`: Base class for custom migrations
|
||||
- `MigrationV1_0_0_to_V1_0_1`: Initial UUID migration
|
||||
|
||||
**Features**:
|
||||
- ✅ Semantic versioning (1.0.0, 1.0.1, etc.)
|
||||
- ✅ Sequential migration application
|
||||
- ✅ Forward compatibility (auto-upgrades old archives)
|
||||
- ✅ Rollback protection (prevents downgrades)
|
||||
- ✅ Extensible migration system
|
||||
|
||||
**Migration Management**:
|
||||
- Automatic detection of needed migrations
|
||||
- Safe, reversible transformations
|
||||
- UUID backfill for old archives
|
||||
|
||||
**Example**:
|
||||
```python
|
||||
from dss.export_import.migrations import MigrationManager
|
||||
|
||||
# Automatic migration on import
|
||||
latest = MigrationManager.get_latest_version()
|
||||
if archive_version < latest:
|
||||
data = MigrationManager.migrate(data, archive_version, latest)
|
||||
|
||||
# Define custom migrations
|
||||
class MyMigration(SchemaMigration):
|
||||
source_version = "1.0.1"
|
||||
target_version = "1.0.2"
|
||||
|
||||
def up(self, data): ...
|
||||
def down(self, data): ...
|
||||
```

## 🔄 Workflow Examples
|
||||
|
||||
### Backup & Restore
|
||||
```python
|
||||
# Backup
|
||||
exporter = DSSArchiveExporter(project)
|
||||
backup_path = exporter.export_to_file(Path("backup.dss"))
|
||||
|
||||
# Later: Restore
|
||||
importer = DSSArchiveImporter(backup_path)
|
||||
restored = importer.import_replace()
|
||||
```
|
||||
|
||||
### Distribute to Team
|
||||
```python
|
||||
# Export
|
||||
exporter = DSSArchiveExporter(my_system)
|
||||
exporter.export_to_file(Path("design-system-v2.0.dss"))
|
||||
|
||||
# Team members import
|
||||
importer = DSSArchiveImporter(Path("design-system-v2.0.dss"))
|
||||
project = importer.import_replace()
|
||||
```
|
||||
|
||||
### Collaborative Merging
|
||||
```python
|
||||
# Team A has local version, Team B shares updates
|
||||
local_project = Project(...)
|
||||
importer = DSSArchiveImporter(Path("team-b-updates.dss"))
|
||||
updates = importer.import_replace()
|
||||
|
||||
# Merge intelligently
|
||||
merger = SmartMerger(local_project, updates)
|
||||
analysis = merger.analyze_merge()
|
||||
merged = merger.merge_with_strategy(
|
||||
ConflictResolutionMode.OVERWRITE
|
||||
)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📊 Architecture Highlights
|
||||
|
||||
### Shadow UUID Strategy
|
||||
```
|
||||
Runtime (Database) Transport (.dss Archive)
|
||||
┌─────────────────┐ ┌──────────────────┐
|
||||
│ id (original) │ │ uuid references │
|
||||
│ projects │───────▶│ .dss file (ZIP) │
|
||||
│ components │ │ (versioned JSON) │
|
||||
│ tokens │ │ │
|
||||
└─────────────────┘ └──────────────────┘
|
||||
(unchanged) (new, export-only)
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- No breaking changes to existing code
|
||||
- Clean export/import logic isolation
|
||||
- Supports distributed collaboration
|
||||
- Backward compatible
|
||||
|
||||
### Multi-Layer Validation
|
||||
```
|
||||
Archive Validation Pipeline
|
||||
├── 1. Archive Integrity (ZIP valid?)
|
||||
├── 2. Manifest Validation (Required fields?)
|
||||
├── 3. Schema Version (Can migrate?)
|
||||
├── 4. Structural Validation (JSON valid?)
|
||||
└── 5. Referential Integrity (All UUIDs resolve?)
|
||||
```
|
||||
|
||||
### Merge Detection
|
||||
```
|
||||
Item Comparison
|
||||
├── New Items (In import, not in local)
|
||||
├── Updated Items (Same UUID, same hash)
|
||||
├── Updated Items (Same UUID, different hash, one-way)
|
||||
└── Conflicts (Same UUID, different hash, both-ways)
|
||||
```
