## Downloading additional data
-### Wikipedia rankings
+### Wikipedia/Wikidata rankings
Wikipedia can be used as an optional auxiliary data source to help indicate
the importance of OSM features. Nominatim will work without this information
This data is available as a binary download:
cd $NOMINATIM_SOURCE_DIR/data
- wget https://www.nominatim.org/data/wikipedia_article.sql.bin
- wget https://www.nominatim.org/data/wikipedia_redirect.sql.bin
+ wget https://www.nominatim.org/data/wikimedia-importance.sql.gz
-Combined the 2 files are around 1.5GB and add around 30GB to the install
-size of Nominatim. They also increase the install time by an hour or so.
+The file is about 400MB and adds around 4GB to Nominatim database.
-*NOTE:* you'll need to download the Wikipedia rankings before performing
-the initial import of the data if you want the rankings applied to the
-loaded data.
+*NOTE:* if you forgot to download the wikipedia rankings, you can also add
+them after the import by running `./utils/setup.php --import-wikipedia-articles`
+and then `./utils/update.php --recompute-importance`.
