The ignore list is maintained at ImageryCompareIgnores. There is also a more detailed reason for each ignore entry documented.

For entries of the kind "... differs ('aaa' != 'bbb')", the first variant is ELI and the second JOSM.

Note that it is possible that there are yellow or blue entries (ELI problems) which are already fixed there in the sources, but not yet pushed to the combined result file imagery.geojson.

This [source:josm/trunk/scripts/SyncEditorLayerIndex.groovy script] compares the following properties:
* source URL
* type (WMS/TMS/WMTS)
* name
* min_zoom and max_zoom
* country code
* shapes
* icon
* best
* date
* copyright/attribution information (permission-ref and terms-of-use-url (JOSM) both map to license_url (ELI))
* projections
* description
* id
* default

This script does not compare all special properties which are available in only one of the two databases.

ELI-only properties according to [https://github.com/osmlab/editor-layer-index/blob/gh-pages/schema.json ELI-schema] are:
* overlay
* i18n
* permission_osm

JOSM-only properties according to [wiki:Maps#Documentation JOSM-schema] are:
* eula
* logo-url
* logo-image
* terms-of-use-text
* mirror
* no-tile-header
* no-tile-checksum
* metadata-header
* valid-georeference
* last-check
* tile-size
* epsg4326to3857Supported
* dirty-mode


The compared files are [https://josm.openstreetmap.de/maps maps] and [https://github.com/osmlab/editor-layer-index/raw/gh-pages/imagery.geojson imagery.geojson].
