Is there a way to visualize / edit the ontology like in webprotoge?

[kalyp-angel]

Hi everyone,

I'm currently testing Utopia and looking for a way to visualize and refine the ontology (classes, relationships, and taxonomies) before running my tasks, similar to how WebProtégé or metaphactory handle schema editing.

Does Utopia have a built-in visual editor or graph viewer for this, or is the standard workflow to edit the ontology externally in a tool like WebProtégé and then import the updated .owl/.ttl file?

Thanks!

Editing, yes; a diagram, no. The Ontology page is a built-in editor, and it works the way WebProtégé does: a class hierarchy on the left (collapsible, with a properties list beside it), and a panel on the right where you edit the selected class or property. For classes that's the label, parent, disjoint classes, the description the extractor reads, attributes and the instances currently in that class; for properties it's domain / range and the axioms (functional, inverse functional, symmetric, asymmetric, transitive, irreflexive, inverse of, sub-property of). Everything the extractor and the reasoner use is edited there.

Importing an .owl / .ttl — a pack or your own — shows a preview of what it would create or change before it applies, and keeps a history. So both flows work: import then refine in the page, or build in the page from scratch.

Two things it does not have yet: a diagram view of the schema (classes and relations drawn as a graph, the metaphactory kind — the graph page shows instances, not the schema), and export back to OWL, so round-tripping through WebProtégé isn't possible for now. If either of those is what you're after, say which and I'll open an issue for it.
