Performing GET on a non-empty [api-x] 'services' indirect container results in 500

[emetsger]

To reproduce:

1. bring up api-x milestone
2. GET the services container (/fcrepo/apix/services)
3. put a resource in the container
4. GET the services container (HEAD will work, but GET does not)

Similar behavior using either Fedora 4.6.0 or 4.7.0 in the 'fcrepo' container.

[birkland]

That's originating from Fedora; not good

[emetsger]

It'd be helpful if you can verify; I can take a dive tonight.

[birkland]

Will do, later tonight or tomorrow!

[emetsger]

@birkland and I confirm that this occurs when not including an ore:describes triple in the resources deposited to the indirect container. Hypothesis is that including the ore namespace definition in fedora-note-types.cnd will fix the issue.

Since we have workarounds (e.g. not having the user of the Milestone directly interact with the 'services' indirect container), untagging this issue for the Milestone, and will submit a patch to Fedora after.
