Subject: [OASIS Issue Tracker] Commented: (ODATA-264) Allow omitting parent key(s) in URLs to contained children

    [ http://tools.oasis-open.org/issues/browse/ODATA-264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32360#action_32360 ] 

Hubert Heijkers commented on ODATA-264:

I hadn't realized this until I saw this issue. In my mind containment implies that, if you look at it from a schema perspective, that the contained entities are by definition keyed to include the containing entity. Therefore the only way to get to a contained entity would be through its containing entity and therefore you'd never need to repeat the key of the containing entity in the key of the contained entity (so I'm all in favor of this change). 

I'd like to take it one step further, if at all possible, and not even have to specify the key properties of the containing entity as part of the contained entity (nor the referential constaint which IMHO is implied by containment). This would allow entities of a type to be contained in various other entitty types without having to create special version for those types depending on the entity they are contained in.

I remember however from our discussions in Zurich that my 'definition' of 'containment' might not exactly match 'containment' so I might be missing the obvious here.
