I am using the UPRN data in QGIS and checking each manually on 
https://osg.scot/portal/ (e.g. UPRN: 137090388). That of course does not 
identify if it is historic and what it is assigned to (the UPRN open 
data is a point not polygon)

Just as an aside to that, there are just over 92,000 USRNs in the Open 
USRN database that are linked to both a named road in OpenNames (via the 
TOIDS LID) and have a name in the NSG, but those two names are not the same.


In a lot of cases that's a simple translation difference - OpenNames is 
English-only, but the NSG uses local names (eg, in Welsh) where 
different to English. Others are relatively minor disagreements over 
spelling (eg, Aaron's Hill v Aarons Hill or Abbey Fields v Abbeyfields). 
The NSG also differentiates, in some cases, between different 
carriageways of dual carriageways, so it has, for example, both Abbey 
Hill Westbound and Abbey Hill Eastbound where OpenNames only has Abbey 
Hill. But, even after excluding these, there are still a significant 
number of streets where the OpenNames name and the NSG name are 
completely different.


I haven't dug particularly deeply into this, as the NSG list of street 
names, although readily available, isn't open data so it's not a lot of 
practical use for my purposes (or, for that matter, OSM). But it is an 
illustration of how even the "official" name of something is not 
necessarily the "correct" name. The naming of roads is a difficult 
matter, it isn't just one of your armchair map games :-)

I'd tend to see the TOIDs are just an internal ID used in OS MasterMap

A street will have multiple TOIDs if it has multiple names. For example, 
USRN 21, part of the A27 Shoreham By-Pass, is linked to TOIDs 
osgb400023625257 and osgb400030480763 - the first for the 
number,m the second for the name.



However, from a practical point of view, if you want to check OSM for

be useful. But perhaps a better solution would be to persuade OS that
they should be including the USRNs in OS Open Roads -- as these are
now the promoted 'gold standard' open unique identifiers for streets.


There's an Open Data Linked Identifiers (LIDS) dataset available from OS 
which links USRNs to TOIDs.


https://osdatahub.os.uk/downloads/open/LIDS

Well, actually, there's two of them, and I'm not entirely sure what the 
difference is:


Road TOID Street USRN 10
RoadLink TOID Street USRN 8

Both of them have exactly the same data format.

The TOIDs in those datasets can then be cross-referenced against OS 
OpenNames to give the OS name for the linked USRNs. Although this isn't, 
always, the same as the official USRN name of the street, which can be 
confusing. But that's because OS (like OSM) maps what is visible, rather

Re: [Talk-GB] Street-name toids

[SK53]

These toids are for the name rather than the physical street - I'm not
interested in toids in general. It is their potential utility in
disambiguating streets which I'm interested in (although as the Derby Road
case I cited is one I'm particularly interested in - it splits multiple
times, has dual carriageway sections, residential service roads, and even
has a residential service road with a different name
 but
addresses belong to the main road - is not split on historical boundaries
not quite as useful as I hoped). Where there is contiguity of the road
segments they can be merged on name alone, but where they are splits - not
just roundabouts - it can be harder to automatically merge the correct
elements. Other examples might be Denman Street in Radford
 & Alfred Street in St
Ann's  both split
into many sections by 1970s re-development. House numbers continue to
reflect that these were once a single street even if the individual
sections have extension names (I presume the street name toids are
different in these cases).

Wrt to UPRNs not referring to streets. This location
 on Robert's site
shows several UPRNs on streets:

   - 10009154384 on Averton Square
   - 10009156248 at start of Longore Square
   - 10009156248 at E end of Fairham Drive

The other non-building UPRNs are the substation in Orston Spinney (verified
as also present in the Asset Register open data) and the secret allotments
(possibly disused or sold as no-longer in the Asset Register) behind
Averton Square.

The land was in medieval times part of the open field system of Sutton
Passeys, a village deserted by the 16th century. It was emparked by the
Willoughby family around 1580 when Wollaton Hall was built, and enclosed by
a wall by Lord Middleton early in the 19th century (part of his defences
against Luddites & others). The land was acquired by Nottingham Council in
the early 1920s
 when
they built the current housing estate. There is an Elizabethan mining adit
or sough built to drain the Willoughby collieries

at Wollaton running somewhere in the vicinity, but other than that no
historical properties in the lifetime of the Ordnance Survey.

I therefore think these UPRNs must refer to the roads.

That is apparently not how OS are positioning TOIDs, according to
Wikipedia 
https://en.wikipedia.org/wiki/TOID 

TOIDs are intended to be persistent, and aimed at integration between
databases. OSM would be one such database, wouldn't it?___

Re: [Talk-GB] Street-name toids

UPRNs are applied to street records (e.g. 320276457 is a street record 
in Fife, I am sure there are many more).


Perhaps all these non-addressable UPRNs should be identified as part of 
the open data?


Related to this is the FOI request that Robert Whittaker made re "list 
of all UPRNs that are classified as 'historic', and a separate list of 
all those classified as a 'parent',,  " - see the ongoing battle
