Subject: [OASIS Issue Tracker] Commented: (ODATA-481) Annotation/Navigation/Path expressions: allow paths to continue after multi-valued navigation to e.g. drill into complex properties
[ http://tools.oasis-open.org/issues/browse/ODATA-481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34779#action_34779 ] Ralf Handl commented on ODATA-481: ---------------------------------- We definitely need several multi-valued navigation segments: all the products ordered by all my customers are My/Customers/Orders/Items/Product - two multi-valued navigations away from me. We can argue whether this identifies a collection produced by concatenating several collections, with identical entities occuring several times, or whether it identifies a set, where each identity appears at most once. I'm fine with both: the "collection/concatenation" definition would be more consistent with complex and primitive instances that don't have an identity, and it would require the "annotation consumer" on top of a generic "annotation library" to remove duplicates if they are not wanted. > Annotation/Navigation/Path expressions: allow paths to continue after multi-valued navigation to e.g. drill into complex properties > ----------------------------------------------------------------------------------------------------------------------------------- > > Key: ODATA-481 > URL: http://tools.oasis-open.org/issues/browse/ODATA-481 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Improvement > Components: OData CSDL > Affects Versions: V4.0_CS01 > Environment: [Proposed][CS02] > Reporter: Ralf Handl > Fix For: V4.0_CSD03 > > > CSDL 14.5.12 restricts path expressions to contain at most one multi-valued navigation property which can only be followed by a single type cast or term cast. > This is overly restrictive: drilling into a complex type path after a navigation is straight-forward, and even multiple multi-valued navigations could be resolved by building the union of all targeted collections. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
