Use _resolve_wikidata in layer mapping.yaml (#731) Mark all tables that should not be populated with the Wikidata international labels with a special OMT-specific flag. This should be ok to merge even before the new tools version is used because imposm seems to ignore anything it doesn't understand. The next tools version will remove it when generating imposm mapping file. 2020-01-21 14:43:21 +00:00			`_resolve_wikidata: false`
Use one pass docs image generation (#751) quicker and cleaner diagram image generation. Remove etl-graph and mapping-graph targets - redundant Also, the obsolete "fields" is still in Imposm's code and both names are accepted, but "fields" is not documented anywhere (PR submitted), and could be removed at any moment. Our docs were not supporting it until this PR, so renaming it at the same time. Several images have been updated due to a more inclusive mapping scan Requires https://github.com/openmaptiles/openmaptiles-tools/pull/147 (merged) 2020-01-23 02:55:22 +00:00			`columns:`
