Nodica
An open-source RDF graph visualisation developed by Ivo Velitchkov, used here as a comparator for explicit semantics and graph navigation rather than as the atlas's underlying implementation.

Summary
Nodica is an RDF graph visualisation project with image-filled nodes. It is used here as a live comparator for semantic graph presentation and as evidence that the contributor's question about explicit semantics was not merely rhetorical.
Implications for practice
The Necessary Tangle uses typed data but has not yet published a standard RDF export. Nodica makes the gap visible and supplies a practical comparison point without requiring the atlas to copy its interface or technology.
Key distinctions
- visualisation tool vs knowledge corpus
- RDF data vs this atlas's JSON model
- comparator vs dependency
Historical development
- RDF
- semantic web
- knowledge graph visualisation
Ideas it depends on
- explicit semantics
- semantic network
- graph visualisation
Further developments
- RDF display
- image-rich graph browsing
Connections to practice
- knowledge graph exploration
- semantic data presentation
Common confusions
- the atlas now runs on Nodica
- RDF removes editorial judgement
- the two projects have identical purposes
Further checks
- compare data-model features explicitly
- prototype a public RDF export from the atlas
- test interoperability rather than infer it
