[OASIS Issue Tracker] Commented: (ODATA-9) allow expressions in the $select query option

[ http://tools.oasis-open.org/issues/browse/ODATA-9?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32641#action_32641 ] 

Michael Pizzo commented on ODATA-9:
-----------------------------------

See related ODATA-10.

We have started to lay the foundation for this in ODATA-253 by allowing results to include properties not specified in metadata. This allows us to define this in the future, or vendors to support a custom extension, without breaking existing clients.

> OData could be extended to allow expressions in the $select query option, allowing derived values to be returned along with the properties of an entity.
> This could be expressed as:
> http://odata.netflix.com/v2/Catalog/Titles?$select=Name,substring(ShortSynopsis,20) as Summary
> or
> http://odata.netflix.com/v2/Catalog/Titles?$select=Name&$extendedSelect=substring(ShortSynopsis,20) as Summary
