Here is my understanding.
SOAP and REST are two different protocols for developing web services. These protocols define standard ways for client devices to interact with a web service. You don’t want to re-invent the wheel every time you want to offer something like a web service to a new client.
Each of these protocols has to be implemented with programs and data.
* On the IBM i, the program that performs the business logic for a web service can be developed in a variety of languages: RPG, COBOL, CL, C Java, PHP, JavaScript via Node.JS, Python.
* XML and JSON are different ways of formatting data for transmission to a client device (laptop, tablet, phone, etc). You can use other data formats as well. XML and JSON are simply two very common formats.
So…
* A client device (e.g., a browser in a tablet) sends a request to a web service on the IBM i. Exactly how the client makes the request depends in part on specifications in the SOAP protocol or the REST protocol.
* The client’s request is received by a web server on the IBM i.
* The web server on the IBM i routes the request to programs that will process it. These programs can include RPG programs.
* The results of the program are formatted as XML or JSON.
* The web server sends the XML or JSON back to the client as a response to the initial request.
This is the gist, anyway, as I understand it. Many details can vary.

Subject: [EXTERNAL] [WEB400] CNVRTTMP.RPGLE has no xml or json -
All the documentation I find about web services talks about SOAP and
REST and XML & JSON. Yet the IBM-supplied example CNVRTTMP.RPGLE is
just a regular program. What am I not understanding?
