Hi Asger
I've verified this, the 404 error has gone away.
It would be useful if there was any way to distinguish between the
non-existence of the target object vs the target object not having the
specified type - is this at all possible?
Thanks
Steve

Hi Asger - thanks for this. Probably I won't get chance until early next
week to test it, but I do want to test it in any case.
Regards
Steve

This branch should fix the problem
https://github.com/fcrepo/fcrepo/tree/fcrepo-1041
Steve, can you test it easily? Otherwise, I will do it.
Regards

Thanks Asger - it returns plain text of the missing object (but this was
from a browser, haven't tried requesting content type of text/xml). I'll
raise a JIRA for this.
Cheers
Steve

That sounds like a bug.
Remember, the 404 message can still contain an xml error. So, does it return
an empty page, or the xml? Using the http return codes might not be in
error.
Should validate returon 2xx when the validation fails?

I am finding that if the target object does not exist, then the validate
method is reporting a 404 error. That's the same error as one would get if
one tried to validate an object that didn't exist; so it would instead be
useful to give the XML error to distinguish between these two cases.
So, if I have the relationship in test:1's RELS-EXT as follows:
<info:fedora/test:1> <info:fedora/test:1> <fedora-model:hasModel>
<info:fedora/test:CModel-1> <info:fedora/test:CModel-1>
<info:fedora/test:1> <info:fedora/test:1> <rel:isMemberOf>
<info:fedora/test:collection> <info:fedora/test:collection>
And then in the CModel CModel-1 I define
<rdfs:subClassOf>
<owl:Restriction>
<owl:onProperty
rdf:resource="info:fedora/fedora-system:def/relations-external#isMemberOf
<http://purl.org/vocab/frbr/core#exemplarOf%22/> "/>
<owl:minCardinality
rdf:datatype="http://www.w3.org/2001/XMLSchema#integer
<http://www.w3.org/2001/XMLSchema#integer%22%3E1%3C/owl:minCardinality>
">1</owl:minCardinality>
</owl:Restriction>
</rdfs:subClassOf>
<rdfs:subClassOf>
<owl:Restriction>
<owl:onProperty
rdf:resource="info:fedora/fedora-system:def/relations-external#isMemberOf
<http://purl.org/vocab/frbr/core#exemplarOf%22/> "/>
<owl:allValuesFrom rdf:resource=
<info:fedora/test:CModel-collection#class>
"info:fedora/test:CModel-collection#class"/>
</owl:Restriction>
</rdfs:subClassOf>
Then if the object test:collection does not exist, on validating test:1 I
get a 404 error because it does not exist.
Does this sound like a bug?
