How to find out the source of sourceId about gisgraphy HOT 3 OPEN

You are write maybe a string that represents the source

Osm-N-xxxxxx
Geo-xxxxxx

And we only keep the most relevant reference if we merge some entry.

That s make sense.

Need code and an import of data

Maybe in v 6.0 :-)

hi

Gisgraphy is not a geocoder for openstreetmap as a lot of others are (Photon, Nominatim only use OSM). it aggregates, de-duplicate, merge several databases (http://www.gisgraphy.com/data/index.php). it is true that we have an openstreetmapId field but if we do this, we should add GeonamesId, openaddressesId, QuattroshapesID, and all the information of all sources.

What about a street in OSM where we add some house number form OpenAddresses...and a city form Geonames where we add a population field from OSM and an alternate name from Open addresses....?

We plan to import other sources and it might be very difficult to use :

1 check the source (OSM, GEONAMES, OSM_GEONAMES,...),
2 look at the specific fields (that can be multiple if merged from several sources)

Actually, the featureId field is the Gisgraphy unique identifier to identify all feature.

of course, I am open to other comments.

The reason for me to open this ticket was, that gisgraphy provides the sourceId.

In the documentation: Reference in the original dataset (e.g : the geonames id or openstreetmap one), so I assume there is some reference back to the original data. Now if I see the source id, how would I know where the entry comes from? I would need to check all the sources gisgraphy takes its data from.

The other OSM things are "nice to have" and I was wondering if we could add this, but I understand that this can lead to problems.
