Subject: [OASIS Issue Tracker] Commented: (ODATA-576) Aggregation: Can we find a better way to represent nested expands?
[ http://tools.oasis-open.org/issues/browse/ODATA-576?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=36273#action_36273 ] Ralf Handl commented on ODATA-576: ---------------------------------- As the other set transformations use positional parameter syntax, I propose to change this to GET ~/Categories?$apply=expand(Products,filter(startswith(Name,'Ski')),expand(Sales,filter(Amount gt 1000))). GET ~/Categories?$apply=expand(Products,expand(Sales)) I.e. the first parameter of expand() is a navigation property path that could also be used in $expand, the optional parameter second parameter can be a filter() transformation or an expand() transformation, the other optional parameters can be expand() transformations: expandTrafo = 'expand' OPEN BWS expandPath [ BWS COMMA BWS filterTrafo ] *( BWS COMMA BWS expandTrafo ) BWS CLOSE > Aggregation: Can we find a better way to represent nested expands? > ------------------------------------------------------------------ > > Key: ODATA-576 > URL: http://tools.oasis-open.org/issues/browse/ODATA-576 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Improvement > Components: OData Extension for Data Aggregation > Affects Versions: V4.0_CSD01 > Environment: [Proposed][Applied] > Reporter: Michael Pizzo > Fix For: V4.0_CSD02 > > > The current aggregation specification use the old path syntax for nested expands. This is inconsistent with the new way to represent expands in core. Can we figure out a syntax for nested expands in aggregation that is consistent with core? -- 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
