Serializing a dataset to JSON and back

In the 90s, most of the Delphi program was always connected to the database server, in a fully-connected scenario. In this situation, dataset serialization was a nice topic. Today, the software world is heterogeneous—different operating systems, programs, and languages must still find a way to communicate and exchange data. We are in the IoT and big data era now!

Now a days, making your data available to other programs or getting data from other software running somewhere in the world is bread and butter, so you can understand that using a proprietary or exotic format is no longer enough. To better understand, the dear and old Dataset.SaveToFile may not be enough.

Let's say we have a JavaScript frontend for our Delphi application server. Your data should be deDelphized (I've just coined this word) and should be independent of the backend programming language or framework used. Delphi has a lot of serialization facilities, but there isn't a well-known...
