WebVOWL displays imported ontology IRI instead of OSO ontology IRI

[spiel-ifremer]

When visualizing OSO in WebVOWL 1.1.7 (https://service.tib.eu/webvowl/#iri=https://w3id.org/earthsemantics/OSO), the ontology title is correctly displayed as:

Observatories of the Seas Ontology (OSO)

However, the IRI displayed just below the title in the right-hand metadata panel is:

http://www.w3.org/ns/prov-o

This appears to be the IRI of an imported ontology rather than the IRI of OSO.

Expected behavior:
WebVOWL should display the main ontology IRI, e.g.
https://w3id.org/earthsemantics/OSO

or the version IRI if this is the intended behavior.

Observed behavior:
The imported PROV-O ontology IRI is displayed instead.

Additional observation: the same issue appears in LOV for OSO.

LOV displays:
URI: http://www.w3.org/ns/prov-o

while the namespace and other metadata are correctly extracted from OSO:
https://w3id.org/earthsemantics/OSO#

This suggests that the issue may affect metadata extraction beyond the WebVOWL visualisation, or that both tools rely on a similar parsing/metadata extraction step.
