Description

Wikidata

https://www.wikidata.org/ is a collaborative knowledge base - it tries to create an identifier for all entities in the world.

With iRail in Belgium we decided to slowly move towards this for persistent identifiers.

Check for example this identifier: http://www.wikidata.org/entity/Q800814

A lot of people added properties we had no clue about (e.g., its architectural style, the fact it’s registered cultural heritage (and is linked to yet another URI for this fact), etc.)

At the bottom of the page you can then find all possible other identifiers given by different systems, including UIC codes, HAFAS codes, or local numbering systems.

And if you then look at OpenStreetMap, then you will see that the building identifier in OSM is linked to this wikidata URI (https://www.openstreetmap.org/way/226276044)

Proposal

What I propose is to have an extra field in the JSON ouput that links to the wikidata identifier of the station. In the case it does not yet exist, it would be great to create it in wikidata, and add basic information such as the other identifiers that you found so far

Contributor guide

Research direction
Explore the Wikidata API to fetch and map identifiers for public transport stations. Investigate existing station IDs in the repository and how they can be linked to Wikidata entries. Look at examples of Wikidata entities for stations and their properties.
