Subject: [OASIS Issue Tracker] Updated: (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:all-tabpanel ] Michael Pizzo updated ODATA-576: -------------------------------- Having special purpose parameters for filter and expand seems less intuitive to read (I have to remember what the parameters represent), brittle (I have to pass a "true" for the second parameter if I don't want to apply a filter) and limited (what happens if I want to apply other expand options in the future? Also, it's confusing having different construction rules from $expand. Why not use the same construction rules as $expand, but with a limited set of expand options; expand and filter? This would also allow us to have a single expand take a list of navigation properties, rather than requiring multiple expand segments. So in the examples above would look like: GET ~/Categories?$apply=expand(Products(filter=startswith(Name,'Ski');expand=Sales,Amount gt 1000))). GET ~/Categories?$apply=expand(Products(expand=Sales)) > 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
