Will it be possible to use implicit tiling with tile hierarchies where some tiles split in 3 rather than 4, e.g. to accommodate the smaller physical area at the poles?...
With implicit tiling, is it possible to imply a transform based on a tile's identifiers so as to be able to define the geometry of the content in a local...
(in the context of implicit tiling) In [OGC API - Tiles](https://opengeospatial.github.io/ogcna-auto-review/20-057.html#toc28), we have this recommendation to return an HTTP response header that indicates whether a requested tile is "empty" or...
Regarding escaping characters, currently CQL2 says: - Single quotes `'` are repeated to escape them within string literals - Backslash `\` is used to escape `_` and `%` in `LIKE`...
- In [7.5.2](http://docs.ogc.org/DRAFTS/21-065.html#_spatial_data_types_and_literal_values) where a link to the WKT standard is provided, it would be very insightful to specifically refer to **Section 7** (mention it in the link) of [_Simple...
- [A.12.1 Conformance Test 49](http://docs.ogc.org/DRAFTS/21-065.html#_conformance_test_49) cql2-text/validate currently says _Validate the filter expression in CQL2 JSON_ but should be saying **_CQL2 Text_**. - The current wording of[ A.12](http://docs.ogc.org/DRAFTS/21-065.html#_conformance_test_49) and [A.13](http://docs.ogc.org/DRAFTS/21-065.html#_conformance_test_50) (_Validate...
This is feedback from trying to implement cql2-text. Implementers (or at least us) face struggles with the current grammar. I think it comes down mainly to these two things: 1....
In Table 2 of [7.6](http://docs.ogc.org/DRAFTS/21-065.html#spatial-operators), some of the mathematical definitions seem incorrect: - `S_CONTAINS` is defined as `S_CONTAINS(a,b) ⬄ b CONTAINS a` -- First, I think it should have been...
CQL2 would actually be very useful as a general expression language, if we would only remove the concept that it needs to evaluates to a boolean expression. Such an expression...
After completing an in-depth review of CQL2 (focused on `cql2-text` so far) as part of our implementation, the following thoughts on arrays and `IN` occurred to me: As discussed in...
