[erlang-questions] JSON for STDLIB
Tue Sep 8 04:06:19 CEST 2015
But if you know about the issues of translating JS JSON into Erlang JSON, you still need to send JSON data through your API.
I guess that we then have to agree on which trade offs we have to pick from all the different JSON libraries.
But for new comers or people that are fine with these trade offs, that can be the easiest and most useful choice.
And I think that the default choice would be the one need.
(Ok now we need to pick the most probable default choice then)

> Defining such a goal would be the first step -- because once Erlang includes something like that as a core library we are *all* stuck with it (and supporting that particular API) forever and ever and ever, amen. Goal definition in the face of sloppy standards is already a non-trivial task. In the presence of decent (but very different) third party libs that already exist it is hard to see what the cost in terms of effort would actually buy us, especially considering that...

> In the face of this ambiguity it is a good thing that we have several third party libs that cater to different interpretations/mapping *and* exhibit different performance characteristics instead of a central canonical library that has to make enough compromises to get included that it just doesn't quite suit anyone's actual use case, and is therefore left lonely in the core libs, unused by most (the way various XML libs in several language core libs have been, for example) but still a derelict maintenance burden.
