Ontobee returns HTTP 200 OK for terms that do not exist

[jamesaoverton]

Ontobee is returning HTTP 200 OK status for terms that do not exist. It should return HTTP 404 Not Found. This is a serious problem.

Example of a non-existent term: http://www.ontobee.org/ontology/OBI?iri=http://purl.obolibrary.org/obo/OBI_1

The page has useless content, an empty RDF element:

On Safari 9.0.1 (11601.2.7.2) and Chrome 46.0.2490.86 (64-bit) the page just never renders. On Firefox 38.0.5 I get an error:

This issue appears new to the new version.

The original version: http://ori.ontobee.hegroup.org/ontology/OBI?iri=http://purl.obolibrary.org/obo/OBI_1 does return 404 Not Found.

Edison, Can you take a look at this issue?

Thanks, Oliver

This is the correct URL for the old version of Ontobee:

http://ori.ontobee.hegroup.org/browser/rdf.php?o=OBI&iri=http://purl.obolibrary.org/obo/OBI_1

It also returns HTTP 200 OK status, which is wrong, but at least the page renders and says "Term Not Found".

I updated the server to return both the 404 status and correct page. Please take a look and let me know if a further action is needed. Thanks.

[jamesaoverton]

Thanks. I now get a 404 for that test page.

However the same empty RDF/XML content appears after the HTML, making this 404 page invalid HTML. I don't think that the RDF/XML should be included.

[e4ong1031]

Okay, the RDF is also removed.
