This package implements the OGC_Common Catalogue Query Language. OGC CQL is the query language to be supported by all OGC Catalogue Interfaces in order to support search interoperability. Catalogue Service Implementation Specification (OGC 04-021r3):
The original BNF was extended thinking in a SQL where expression. The original BNF is reproduced to indicate the extensions highlighted with bold characters.
Extensions in original BNF

The parser was generated using javacc. In CQLGrammar.jjt file you can see the input grammar for javacc required to parse CQL with extensions.
