Subject: [OASIS Issue Tracker] Commented: (ODATA-372) Addressing Derived Types
[ http://tools.oasis-open.org/issues/browse/ODATA-372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33317#action_33317 ] Stefan Drees commented on ODATA-372: ------------------------------------ I think the samples given by Ralf are derived from those in section 4.9 as he indicates, thus "the Spec" contains "such details" already ;-) Is there a possibly less irritating sample you might offer for the follow-up question, where you only want the base type instances not including any derived type instances? I find myself caught in regarding these derived types as concrete types for the virtual type "VirtualSystem" ... and wonder if the intended latter query is a quest for NULLs so to say, those where another concrete type was not yet defined to put candidates in ... as I said, I am not sure where you are heading at ... otherwise $filter is a nice system query option ... Otherwise I would second to close the issue with no action. > Addressing Derived Types > ------------------------- > > Key: ODATA-372 > URL: http://tools.oasis-open.org/issues/browse/ODATA-372 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Task > Components: OData URL Conventions > Affects Versions: V4.0_WD01 > Reporter: Ramanjaneyulu Malisetti > Assignee: Ralf Handl > Priority: Minor > > I would like to seek clarification on below scenario.... > Suppose, I have 3 entity types 1) VirtualSystem 2) HyperVSystem and 3) VMWareSystem. Here, VirtualSystem is the base EntityType for both HyperVSystem and VMWareSystem. Now, if I define EntityContainer having only EnitySet for VirtualSystem. Are the following URLs correct? > > 1) http://host/service/VirtualSystems > Returns only instances of EntityType VirtualSystem > > 2) http://host/service/VirtualSystems/HyperVSystem > Returns only instances of EntityType HyperVSystem > > 3) http://host/service/VirtualSystems/VMWareSystem > Returns only instances of EntityType VMWareSystem > > How to get all instances of VirtualSystem, HyperVSystem and VMWareSystem in a single query? > -- 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
