addr:place tag has often been incorrectly used here in the UK. The tag
addr:place is meant to be used when the address does <u class="">not</u>
reference a street (tagged with addr:street) at all. This is frequently
seen in small villages in continental Europe which often don't have any
street names at all.</div><div class=""><br class=""></div><div class="">In the UK most cases of addr:place and addr:street being used together
are incorrect and are cases where addr:suburb should have been used
instead of addr:place. You can browse the <a rel="nofollow" href="https://nominatim.org/qa/#map=8.06/53.26/-0.64&layer=addr_place_and_street" target="_blank" class="">Nominatim QA</a> to find examples and help clean these up. </div><div class=""><br class=""></div><div class="">To help with this clean up effort I have tested an approach in JOSM that some might consider as captured by the Automated Edits code of conduct. I therefore wanted to share this process before proceeding.</div><div class=""><br class=""></div><div class="">Step 1:</div><div class="">Identify a potentially incorrect use of the addr:place tag. To do this I am looking at the list of values used on TagInfo GB and checking if any of these are villages/towns. If they are then there is a high chance that the addr:place tag is incorrect.</div><div class=""><a href="https://taginfo.openstreetmap.org.uk/keys/addr%3Aplace#values" target="_blank" class="">https://taginfo.openstreetmap.org.uk/keys/addr%3Aplace#values</a></div><div class=""><br class=""></div><div class="">Step 2:</div><div class="">Open the data in JOSM using an overpass query. An example query I am using to download the data is:</div><div class=""><br class=""></div><div class="">[out:xml][timeout:90];<br class="">{{geocodeArea:England}}->.searchArea;<br class="">(<br class=""> nwr["addr:place"="Eccleston"](area.searchArea);<br class="">);<br class="">(._;>;);<br class="">out meta;</div><div class=""><br class=""></div><div class="">Step 3:</div><div class="">Inspect the data in JOSM paying particular attention to other addr:* tags. To do this I start by doing a Ctrl+F and search for e.g. "addr:place"="Eccleston". This selects all the features with this tag. I can then see the full range of addr:* tags used on these features. High use of addr:street reiterates the incorrect use of addr:place. I can also see if the addr:suburb tag has been used on any features -> if it has then I go investigate this separately. I also investigate uses of all other addr tags except housenumber/name, unit, flats and street.<br class=""></div><div class=""><br class=""></div><div class="">Step 4<br class=""></div><div class="">Change addr:place to add:suburb. I get to this stage quicker if step 3 does not identify any conflicting addr:* tags (e.g. if the only other addr tags are housenumber/name and street). The more addr:* tags there are the more I look into individual OSM features before making this change.</div><div class=""><br class=""></div><div class="">As always, if in doubt then I don't proceed.</div><div class=""><br class=""></div><div class="">How do you feel about this sort of approach? With proper time spent carefully looking at the other addr tags that have been used, then I believe it is a low risk edit.<br class=""></div></div><div class=""><br class=""></div><div class="">P.S. Feel free to check out the results of a couple trials I made. e.g. <a href="https://www.openstreetmap.org/changeset/116122672#map=14/53.6500/-2.7281" target="_blank" class="">https://www.openstreetmap.org/changeset/116122672#map=14/53.6500/-2.7281</a> I'll pause on making more as I realise I should get the discussion going first.<br class=""></div><div class=""><br class=""></div><div class="">Thank you,<br class=""></div><div class=""><div dir="ltr" class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><span style="color:rgb(0,0,255)" class=""><b class="">Rob</b></span><br class=""></div></div></div></div></div></div>
