Hello @Poortinga_YPE ,
You are right, the Cluny museum appears twice in the database (but not 4 times?), and it is the same problem as the example quoted above: we have two data providers for the City of Paris, namely the Paris tourist office and the Ile de France regional tourist committee. We are going to check with them again to improve this problem of duplication.
Normally, duplications are rare because we have chosen to have only 1 supplier per geographical area (except for Paris). However, we can see that some suppliers send data outside their zones.
This is an essential point for the quality of the data, and we are working on it. The deduplication is not technically simple because there is generally no criterion for matching data (there is no unique identifier on which we could base ourselves).
Have a nice day and thanks for your feedback!
