In Switzerland that would require you to deposit at least 25k or you can not use a fantasy name.
And even then there's a public entry that you are the owner, there are no anonymous LLCs in Switzerland.

I took Ghislain Fourny's Big Data course at ETH last year and found working with JSONiq quite pleasant. I think it makes writing complex queries quite simple, and way more readable than trying to do the same in a query language like SQL, XPath, etc, and since json seems to be fairly standard it is also useable out-of-the-box for a lot of data "in the wild".
It is my impression that the tooling is a bit difficult to setup though.
Another thing is that it supposedly can scale to absolutely massive datasets, since there is a Rumbe/Hadoop backend.
Was the same for me. Like others here, I was quite sceptical because I use Python / JS on a daily basis as a JSON query language, but after I got used to it, I really liked the language and think that it could increase my productivity if I would use it more often.
