-------------------------------------------
Fix Version/s: unomi-3.1.0
(was: unomi-3.0.0)
> Enhanced Technical Documentation with Integrated Diagrams

> Key: UNOMI-882
> URL: https://issues.apache.org/jira/browse/UNOMI-882
> Project: Apache Unomi
> Issue Type: Sub-task
> Components: unomi(-core)
> Affects Versions: unomi-3.0.0
> Reporter: Serge Huber
> Assignee: Serge Huber
> Priority: Major
> Fix For: unomi-3.1.0

> h2. Rationale
> Our current documentation faces several challenges:
> h3. Current Pain Points
> * *Documentation Maintenance*:
> ** Diagrams are maintained separately from documentation
> ** Binary image files in version control
> ** Manual updates required when architecture changes
> ** Inconsistent diagram styles and formats
> h3. Development Impact
> * Documentation becomes outdated quickly
> * High overhead in maintaining technical diagrams
> * Difficulty in reviewing diagram changes
> * Inconsistent representation of system architecture
> h3. User Experience
> * Outdated visual documentation
> * Inconsistent representation across documents
> * Difficulty understanding complex interactions
> * Limited visualization of system architecture
> h2. Proposed Solution
> Integrate automated diagram generation directly within our AsciiDoc
> documentation using a combination of PlantUML and GraphViz.
> h3. Technical Components
> * *PlantUML Integration*:
> ** C4 model support for architecture diagrams
> ** Sequence diagrams for interactions
> ** Component diagrams for services
> * *GraphViz Support*:
> ** Dependency graphs
> ** Flow diagrams
> ** State machines
> h3. Implementation Requirements
> * GraphViz 2.40+
> * PlantUML integration
> * AsciiDoctor Diagram extensions
> * Build system integration
> h3. Build Integration

> h3. Build System Integration
> * *Automated Requirement Checking*:
> ** PowerShell build script (`build.ps1`) now includes:
> *** Automatic detection of GraphViz installation
> *** Clear installation instructions if missing
> *** System requirement validation
> *** Colorized output for better visibility
> ** Shell script (`build.sh`) includes:
> *** GraphViz dependency checking
> *** Platform-specific installation guidance
> *** Enhanced error reporting
> *** Progress tracking for long operations
> h3. Build Script Features
> * *Requirement Validation*:
> ** Checks for Java, Maven, and GraphViz installations
> ** Validates system resources
> ** Verifies tool versions
> * *User Experience*:
> ** Clear error messages
> ** Installation guidance
> ** Progress indicators
> ** Colorized output (when supported)
> * *Error Handling*:
> ** Detailed error reporting
> ** Recovery suggestions
> ** Platform-specific guidance
> h3. Installation Support
> * *Automated Installation Instructions*:
> {noformat}
> # When GraphViz is missing, the build script provides platform-specific
> guidance:
> # macOS
> brew install graphviz
> # Ubuntu/Debian
> apt-get install graphviz
> # Windows
> choco install graphviz
> {noformat}
> * *Version Validation*:
> ** Checks GraphViz version compatibility
> ** Verifies dot command availability
> ** Ensures proper PATH configuration
> h3. Technical Achievement
> * Successfully integrated PlantUML
> * Established consistent styling
> * Version-controlled diagram sources
> * Build process integration
> h2. Benefits Realized
> h3. For Developers
> * *Maintenance*:
> ** Source-controlled diagrams
> ** Easy updates with code changes
> ** Consistent styling
> ** Integrated review process
> h3. For Documentation
> * *Quality*:
