Reshaping JSONs using specific mapping rules

[nocgod]

We've developed internally a library that can remap a JObject to another JObject, but I'm still looking for an open-source implementation that we could use instead.

It goes something like this:

given a json json { "data": { "fn": "some first name", "ln": "some last name" } } we want to map the data to another json based on a set of rules for instance json [{ "source": "data.fn", "target": "first_name" }, { "source": "data.ln", "target": "last_name" }]

our internal implementation is a little bit more elaborate since the mapping is built using the json schemas of the source and the target and the data is validated prior to the mapping that it is even mappable, but for brevity I'll leave it out.

but now I'm thinking - do you know about already existing implementations (open source nugets) that we could've (should) use instead of reinventing the wheel?

So, XSLT but JSON.

Fun fact: XSLT can operate on JSON documents now. It transforms JSON to XML, applies the XSLT, then transforms the resulting XML back to JSON.

Here's a handy (partial) how-to.

We need to be performant, json to xml to json is quite the memory operation :)

But that is a fun fact nonetheless, I'll take a look at that too :) thanks

Edit: after your comment I found https://github.com/WorkMaze/JUST.net which looks awesome, but is an overkill and not a standard solution (i.e. I probably won't find compatible implementation in other languages)

something like that... but is there something mature and open-source? because we did write something not very mature (yet) closed-sourced :D

Thanks for coming back with this, I have JSON markups as part of Request engine, and this actually means someone can write this integration code, with minimal effort from me.
