REST RQL Java Implementation

Question

Is there any java implementation of "RQL" (Resource Query Language), there is an implementation of "FIQL" (Feed Item Query Language) here but it is part of CXF, so my questions are :

1. Can I use the FIQL engine of CXF implementation separably from using CXF, in case I'm using Spring MVC
2. Is there implementation of RQL
3. RQL vs FIQL

Answer 1

R-SQL parser is partial implementation of FIQL:
