Ontologies outside a slice are accessible via the slice subdomain

[alexskr]

While reviewing slice behavior in BioPortal, I noticed that accessing an ontology directly via a slice-specific subdomain bypasses the expected slice filtering.

Example:

obo-foundry.bioportal.bioontology.org/ontologies/STY
The STY ontology is not in the OBO Foundry slice but is accessible from that slice.

Questions:

• Is this expected behavior?
• Should access to ontologies through slice-specific subdomains be restricted only to those included in the slice?

One person's opinion: I don't think that is expected behavior.

My understanding of a slice is that its purpose is to restrict access to only the ontologies in the slice. The above result negates that goal, at least to some extent.

So I think it should be restricted, yes.
