Serge Huber created UNOMI-882:
---------------------------------
Summary: 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
Fix For: unomi-3.0.0
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* Documentation becomes outdated quickly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* Outdated visual documentation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
