OGC Membership approves Common Query Language (CQL2) as an official OGC Standard
CQL2 is a filter grammar supporting both text and JSON encodings that can be easily integrated into software applications.
Filter Encoding
Overview
This jointly developed OGC and ISO TC/211 International Standard describes an XML and KVP encoding of a system neutral syntax for expressing projections, selection and sorting clauses collectively called a query expression. These components are modular and intended to be used together or individually by other standards which reference this International Standard.
