[OASIS Issue Tracker] (ODATA-1105) Simplify selection of properties of complex type

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

     [ https://issues.oasis-open.org/browse/ODATA-1105?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Pizzo updated ODATA-1105:
---------------------------------

    Proposal: 
Harmonize syntax for complex properties within $select with syntax for navigation properties within $expand:
- complex property can be followed by parentheses containing
  - $expand nested in $select.  - $select with same recursive syntax
  - $compute to place computed properties within the complex type
  - for collection-valued complex properties also $filter, $search, $count, $orderby, $skip, and $top within the parentheses
  - support assigning values to parameter aliases within $select

Extended $select syntax also allowed for $select nested within $expand.

> Currently, properties of complex types are individually selected, as in:
> $select=Name,Address/City,Address/State,Address/Zip
> We could simplify the syntax for selecting individual properties of a complex type, similar to expand options.  Something like:
> $select=Name, Address($select=City,State,Zip)
> or
> $select=Name, Address(City,State,Zip)
> The first syntax would support adding the ability, for example, to $filter or $sort a collection of complex types.
> We could put $compute (or an inline expression) in the $select in as a scoped value (couldn't be used in filter/sort).
> Putting $expand in $select brings in all the issues of combining $expand and $select and results in two ways of doing expand.
