FYI, one of the main goals of the Muldis D language is to be an "open source SQL 
standard".  It is intended to satisfy both relational and NoSQL folks, and 
predates UnQL significantly.

Muldis D has always been published openly and is comprehensive enough to cover 
anything that SQL does, and anyone is welcome to improve it.

Moreover, this standard has built-in resilience against "embrace, extend and 
extinguish" by including explicit versioning with authorities (Perl 6 inspired 
that feature), so that if anyone forks the language, it is possible for the 
different versions to be easily distinguishable and non-conflicting, and in a 
more benign respect it is designed to be extensible so DBMSs can be free to 
evolve under it, adding unique features, while not causing compatibility 
conflicts with other DBMSs in the process.

Note that I have fallen behind in specifying a number of intended significant 
design improvements/simplifications to the spec proper, though much of this is 
hashed out in the laundry list TODO_DRAFT file in github.
