Subject: [odata-comment] Specification Improvement (4.0 & 4.01): The document "OData Version 4.0, Part1: Protocol" specifies in section "11.4.6.2 Remove a Reference to an Entity"

 

The document "OData Version 4.0, Part1: Protocol" specifies in section

"11.4.6.2 Remove a Reference to an Entity":

 

     For collection-valued navigation properties, the entity reference of

     the entity to be removed MUST be specified using the $id query

     string option.

 

It would be nice if instead of or at least additional to using the $id query

option it would be allowed to use the key after the navigation property

to specify which entity is referenced.

 

Example:

    DELETE http://host/service/Customers(1)/Orders/$ref?$id=../../Orders(4711)

could be expressed as

    DELETE http://host/service/Customers(1)/Orders(4711)/$ref

 

This avoids a mandatory query option, handling of nested URLs, and parsing

of relative or absolute URLs including verification that the URL is fitting;

last but not least it is shorter and easier to understand.

 

Kind Regards,

Oliver Heinrich
