<div dir="auto">Thanks for all the comments so far. Please keep them coming.<div dir="auto"><br></div><div dir="auto">Just to be clear, we are not trying to replicate the way Royal Mail or PAF do it. Instead what we want is to define a way in which someone can take the addr tags and write out an address on an envelope. Currently this doesn't seem possible in a consistent way.</div><div dir="auto"><br></div><div dir="auto">Personally I was hoping to do this using existing tags rather than creating new ones. I know this will result in some work changing a few things to conform to the new standard but introducing new tags would also create work for existing OSM features.</div><div dir="auto"><br></div><div dir="auto">For context, 17 years of OSM has led us to mapping (inconsistently) just around 2.5million addresses. In total UK has 27 million residential addresses plus unknown millions of non-residential addressees.</div><div dir="auto"><br></div><div dir="auto">Hopefully we can find a solution that breaks as little as possible and results in as little re-work as possible but we need to be realistic that there is no silver bullet that solves everything without breaking anything.</div><div dir="auto"><br></div><div dir="auto">Let's get this right now so that we can confidently map the other 25+ million addressees knowing we're using a system where is possible to use OSM to write an envelope.</div><div dir="auto"><br></div><div dir="auto">I'll end by saying that, despite not aiming to replicate RM/PAF, it does seem that we will need a way of recording the parent+child type arrangement. Because this hasn't been agreed across the UK community to date, we now have more and more tags being created (e.g. addr:terrace, addr:site, addr:parentstreet, addr:locality). I suspect some have been created because the child element is not a street and hence people don't want to use the addr:street+addr:parentstreet combination. Do we need to clarify that addr:street can be used for non-street child elements or is that a no-go as well?</div><div dir="auto"><br></div><div dir="auto">P.s. I'll respond to the ideas received in another email.</div><div dir="auto"><br></div><div dir="auto">Best regards</div><div dir="auto">Rob</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 21 Dec 2021, 17:03 Rob Nickerson, <<a href="mailto:rob.j.nickerson@gmail.com">rob.j.nickerson@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hi all,</div><div><br></div><div>I hope many of you are now managing to relax and enjoy the Christmas break. For those still working, I hope it drops away soon and you are able to enjoy a break soon.</div><div><br></div><div>As previously discussed, OSM UK is running a project to make it easier to collect address data in the UK. As a quick recap, the aim is to create a simple user interface where anyone (existing and new mappers) can add address data. The interface will be populated with a series of points where we believe there to be an address (filtered to avoid duplication with any existing OSM data) and the user will be asked to input the top part of the address.</div><div><br></div><div>One of the challenges we have is making sure that the right part of the address is assigned to the right addr:* tag in OpenStreetMap. We have therefore been studying the address tags and how they are used in the UK. Suffice to say it is not straightforward and without its inconsistencies. I have therefore produced the following wiki page to help other mappers understand the soup of available tags and which are better / worse to use.<br></div><div><br></div><div><a href="https://wiki.openstreetmap.org/wiki/Addresses_in_the_United_Kingdom" target="_blank" rel="noreferrer">https://wiki.openstreetmap.org/wiki/Addresses_in_the_United_Kingdom</a> <br></div><div><br></div><div>You will see on the page that one of the concepts we struggle with is when you need both a parent and child part of the local area to describe a complete address. In Royal Mail's language they use a "thoroughfare" and "dependent thoroughfare" whilst in OpenStreetMap we seem to have multiple tag options. For the OSM UK project we want to keep it simple and not bombard new mappers with the details of conflicting / inconsistent OSM tags. As such we plan to use addr:place (child) and addr:street (parent) for these parent and child relationships.</div><div><br></div><div>Please let me know if you have any feedback. I will try my utmost to take this on board but a word of warning: I have found OSM tags to be inconsistent and not straightforward. I will try my best but cannot work miracles even at this time of the year!<br></div><div><br></div><div>P.S. The wiki page is very much focussed on the top part of an address. This is intentional as it is what we will focus on in the OSM UK project. These address parts require ground survey (or local knowledge) whereas some of the lower elements of an address can be determined by admin boundaries / nearness to existing OSM data.<br></div><div><br></div><div>Thank you<br></div><div><div><div dir="ltr" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><span style="color:rgb(0,0,255)"><b>Rob</b></span><br></div></div></div></div></div></div></div>
