"Download as RDF" UI action does not work #144
Description
Describe the bug
Clicking "Download as" → "RDF" does not return the RDF representation, although retrieval itself works.
To Reproduce
Steps to reproduce the behavior:
- Go to https://identifier.buildingsmart.org/uri/buildingsmart/ifc/4.3/class/IfcWall
- Click "Download as" → "RDF"
- Observe that no RDF is returned / download fails
Expected behavior
The RDF representation should be returned.
Desktop:
- OS: macOS
- Browser: Chrome
- Version: 146.0.7680.80
Additional context
- RDF retrieval works via direct request as described on https://technical.buildingsmart.org/standards/ifc/ifc-formats/ifcowl/ → endpoint is functional
- Logging in does not change behavior → likely UI issue
Related, but different issues:
- curl example on ifcOWL page fails when copied + suggestion for RDF access via content negotiation technical.buildingsmart.org#7: documents RDF access via HTTP content negotiation, not the GUI download
- Hierarchy missing in ttl output? #121: Turtle/content issue, not the GUI download action
Also note that supporting HTTP content negotiation on the identifier URI (as suggested in #7) would align with Linked Data best practices and allow clients to resolve URIs directly without relying on the UI.
