Component included in SAP NetWeaver Foundation for Third Party

Hi Experts,

Now, our team discussing on how we can use integrate based on ABAP Technology to integrate Enterprise Systems.

Then, we discovered the License, that SAP delivered, "SAP NetWeaver Foundation for Third Party".

I heard this license allows client to develop custom applications on standalone NetWeaver Application Server(ABAP/Java).

I think that the ABAP instance contains SAP_BASIS and SAP_ABA, and I have information that it allows to use also BRFplus,

but it is a little vague what function can be used.

Does anyone knows what component is included that license?

Especially, we want to know whather we can use NetWeaver Gateway with  standalone NetWeaver Application Server or not.

Best Regards,
