Introduction
Mermaid.js is a popular diagramming tool that simplifies visualization, but when it comes to semantic modelling, it has limitations. While it excels in flowcharts, Gantt charts, and entity-relationship diagrams, it lacks key features needed for effective semantic modelling.
What’s Missing in Mermaid for Semantic Modelling?
- Ontology Support – Mermaid does not support RDF, OWL, or other ontology-based modelling standards crucial for semantic relationships.
- Formal Semantics – Unlike dedicated semantic modelling tools, Mermaid lacks logic-based interpretations that define precise meanings.
- Data Integration – It does not natively support linked data or SPARQL queries essential for knowledge graphs.
- Expressive Constraints – The tool cannot enforce constraints like cardinality and domain-specific rules.
Conclusion
While Mermaid is great for general visualization, it needs enhancements for true semantic modelling. For complex knowledge representations, specialized tools like Protégé or WebVOWL are more suitable.
