Mmm, I think Dimensions is a different case, as Dimensions are tied to WMS-T [0] and the query parameter is defined as &TIME=...,... &TIME=... etc OR elevation: &ELEVATION= GeoServer has (besides dimensions) even some more use of 'variables' which you can use in different places: - possible variable substitutions in sld's [1] &&env=name1:value1;name2=value2&... - sql view parameters [2] &viewparams=p1:v1;p2:v2;... - format options in CQL queries [3] &format_options=param1:value1;param2:value2;... I think the 'expressions'-variables you are talking about are most close to the viewparams (though if it only filters the styling itis a sld one...). My point: let's define a 'common' param, shared between different FOSS wms's instead of coming up with our own wheel :-) Regards, Richard Duivenvoorde [0] https://anitagraser.com/2011/06/10/wms-t-support-in-geoserver-and-mapserver/ [1] http://docs.geoserver.org/stable/en/user/styling/sld/extensions/substitution.html [2] http://docs.geoserver.org/latest/en/user/data/database/sqlview.html [3] http://docs.geoserver.org/latest/en/user/services/wfs/vendor.html _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
