2. At the top of the opened page click on "Discussion"
3. Append in the opened text box the description of the problem you found in the data

How to contribute to linked entities

OSM-Wikidata Map gets entities linked to map features from [OpenStreetMap](https://www.openstreetmap.org/welcome) and information about the etymology subjects from Wikidata.

Some tools make it easy to contribute to OpenStreetMap by linking entities:

• osm.wikidata.link helps discovering missing wikidata tags and find their possible value

If those tools aren't enough for your needs and you want to manually add or correct entities linked to a map feature you can do it on openstreetmap.org.

You can learn how to map on the official welcome page and on LearnOSM.

The wikidata ID of an item (object/person/...) can be found by searching its name on wikidata.org, once the subject will be opened its alphanumeric ID will be both on the right of the title and in the URL.

OSM-Wikidata Map obtains linked entities from multiple tags:

Possible patterns of tags and properties used by OSM-Wikidata Map are listed in README.md. Examples of tags and properties to be configured for these patterns are:

In order to display an entity linked to a map feature you need to create one of these combinations. Here's how to do it:

1. Find the element of interest on openstreetmap.org
2. Check out the element's tags:
   • If one of these tags is present and this website's data has been updated but the element isn't available on the map, then the tag value may contain an error (like not being a valid Wikidata ID).
   • If one of these tags is available but links to the wrong entity, search on Wikidata the ID for the correct entity ID and edit the incorrect tag with the new ID.
   • If the element has a wikidata tag check the referenced Wikidata entity.
     • If it does not represent the same real world object of the OSM element, search the correct one and change it.
     • If it contains a    relation check that it links to the correct entity. If it is absent, add it:
       1. Click "+ Add statement"
       2. On the left choose the appropriate property among those above
       3. On the right search the desired entity to use as the value
   • If none of these tags is present, you can link the Wikidata item for the entity directly to the map feature:
     1. Search the entity on Wikidata
     2. If the Wikidata entity for the subject you want to use is not available you can create it on https://www.wikidata.org/wiki/Special:NewItem using the instructions on that page.
     3. Add to the OpenStreetMap element the appropriate tag among those above with the Wikidata ID as value.

How to contribute to the background map

The background maps are provided by external providers which are based on OpenStreetMap such as Maptiler, Stadia Maps, Jawg and Mapbox.

You can improve OpenStreetMap data on openstreetmap.org. You can learn how to map on the official welcome page and on LearnOSM.

Keep in mind that these external providers doesn't update the map immediately so if you edit something on OpenStreetMap it may take some time to appear in the map.
