[OASIS Issue Tracker] Commented: (ODATA-144) "Scoping" syntax for $select and $aggregate

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

    [ http://tools.oasis-open.org/issues/browse/ODATA-144?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31588#action_31588 ] 

Michael Pizzo commented on ODATA-144:
-------------------------------------

I would suggest that, if we adopt the new syntax, we no longer support the path syntax for $select in the specification (services are free to support this older syntax for backwards compatibility with existing implementations.)

> The current syntax for $select requires to qualify each single included property with its navigation path. We propose an alternative/additional syntax that allows grouping by path:
>     $select=Items/(Price,Currency,Quantity,Unit) 
> The same notation would be useful for the data aggregation extension:
>     $aggregate=Sales/(sum(Amount),average(Amount) as AvgAmt)
