Subject: [OASIS Issue Tracker] (ODATA-996) Added/deleted links: "relationship" should be navigation property path

    [ https://issues.oasis-open.org/browse/ODATA-996?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=64327#comment-64327 ] 

Michael Pizzo commented on ODATA-996:

In addition to complex properties, included type cast segments (may be necessary to cast to derived complex type) and members of ordered collections (since nested delta representations only work for entity collections) in path.

>             Project: OASIS Open Data Protocol (OData) TC
>          Issue Type: Bug
>          Components: OData JSON Format
>    Affects Versions: V4.0_ERRATA03
>            Reporter: Ralf Handl
>             Fix For: V4.01_WD01, V4.0_ERRATA04
> Sections 14.3 and 14.4 define the format for added/deleted links and state that the property "relationship" contains the name of the navigation property that is changed.
> The name alone isn't sufficient for navigation properties nested within complex properties, "relationship" should instead contain the path to the navigation property.
> Collection-valued complex properties with nested navigation properties need special attention.
> Maybe restrict change tracking to ordered collections of complex instances with nested navigation properties, or require "nested delta" format for these in V4.01
