Can the output of a REST service be simplified?

We have a REST service:

http://mysap.dummy.com:8000/sap/opu/odata/sap/ZFRAG_LIBRARY_SRV/FragranceLibrarys(Material='30121790')?$expand=FragLibrary,VATChar,Value&$format=json

The output of this service is quite large. There seems to be some additional data generated which we don't need and rather don't want to see.

Especially the URI that is repeated every time. Is there an option that does not show this data?
