System Documentation

What problem does it solve?

Convert hand-drawn or modeling tool UML class diagrams from images (JPEG, PNG, PDF) into a structured domain-model.json format to feed into the uml-workflow-v2 pipeline. It also supports multi-language OCR (Japanese/English) and merging with an existing model to keep workflows consistent.

Core Features & Use Cases

  • Multi-format extraction: supports JPEG, PNG, and PDF inputs to extract classes, attributes, methods, and relationships.
  • Merge capability: creates or updates domain-model.json and preserves metadata to maintain traceability.
  • Validation & integration: outputs a standards-compliant domain-model.json and integrates seamlessly with Step 6+ of the UML workflow.
  • Multi-language OCR: detects Japanese and English text to generate appropriate entity names and japanese_name fields.

Quick Start

Upload a class diagram image or PDF and request conversion to domain-model.json.
