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
* overlay

This script first tries to find matching URLs and in the remaining data it tries to find matching IDs. Everything left will be reported.
The 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:
* 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
* mod-tile-features
* custom-http-headers
* default-layers
* format
* transparent
* minimum-tile-expire
* category

Note that terms-of-use-url isn't converted to license_url in the geojson output.

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

For easier syncing between JOSM and ELI there are two features:
* [/maps?format=geojson&pretty=true This] file displays the JOSM database in ELIs geojson format. Note that this file may contain JOSM-only properties (see above) which are not (yet) supported by the ELI schema. Possibly you need to remove these properties when syncing to ELI.
* The command `ant dist imageryindexdownload` in the JOSM svn repository produces several files including `imagery_eliout.imagery.xml` which is the ELI database in JOSMs xml format. (ELI has an XML output too, but it is without the indentation JOSM uses in the wiki, which makes syncing hard.)

**New data is usually up to date within a minute but may be delayed up to half an hour! **
