Hi all, I would like to propose moving the cql2-text and cql2-json unsupported modules to supported land.
In particular, the modules support the CQL2 filter language <https://docs.ogc.org/is/21-065r2/21-065r2.html> in its text incarnation (similar to ECQL) and its JSON incarnation (for the JSON documents that need to express a filter, and general ease of parsing from machinery (yep, it's 2024 and writing a text parser is still hard). The modules have been used for a while in the GeoServer OGC API modules, and have been recently overhauled to match the current standard. The CQL2 specification is modular and allows a subset of all possible filters and expression to be implemented. The CQL2 modules currently support the following requirement classes: - http://www.opengis.net/spec/cql2/1.0/req/advanced-comparison-operators (like, between, in) - http://www.opengis.net/spec/cql2/1.0/req/property-property (comparison between two properties) - http://www.opengis.net/spec/cql2/1.0/req/functions (extensible functions) - http://www.opengis.net/spec/cql2/1.0/req/basic-spatial-functions (point/bbox/s_intersects) - http://www.opengis.net/spec/cql2/1.0/req/basic-spatial-functions-plus (all other single and multi geometry types) - http://www.opengis.net/spec/cql2/1.0/req/spatial-functions (S_CONTAINS, S_CROSSES, S_DISJOINT, S_EQUALS, S_INTERSECTS, S_OVERLAPS, S_TOUCHES, S_WITHIN) The following are not supported, but may be implemented in the future: - http://www.opengis.net/spec/cql2/1.0/req/case-insensitive-comparison (CASEI function) - http://www.opengis.net/spec/cql2/1.0/req/accent-insensitive-comparison (ACCENTI function) - http://www.opengis.net/spec/cql2/1.0/req/temporal-functions (too many to list, various temporal comparisons between instants and intervals) - http://www.opengis.net/spec/cql2/1.0/req/array-functions (support for array data types) In terms of gold stars <https://docs.geotools.org/latest/developer/procedures/check.html> for graduation: - Correct headers: check - Releasable no blocking bugs in jira: check - Used in anger: sort of, GeoServer OGC API has been using it for a while. Check. - Optimised: Parsing is as good as it can be. Check. - Supported: In terms of maintainers, it will be me, Andrea Aime - Documentation. A pull request with documentation is available here <https://github.com/geotools/geotools/pull/4987>. That would be 4+ stars, enough for graduation. In addition to that: - cql2-text has a test coverage of 74% (when run with -Ponline) - cql2-json has a test coverage of 70% (when run with -Ponline) - Both modules pass the QA checks The CQL2 modules have online tests that download some test data from the OGC web site (it's a 1MB+ geopackage used for the CQL2 Abstract test suite). In the PR for graduation we'll also add an online build Github action running the two tests. Votes and feedback welcomed! Cheers Andrea == GeoServer Professional Services from the experts!
