I don't think it has been mentioned, but having the link to FHRS is one way of keeping on top of changes in places where we have fewer active mappers. That is, by monitoring for changes in FHRS we can identify closures, takeovers, new cafes etc (assuming a detectable change in the source data). In a way this is similar to the ref:navads tag that was added to Shell petrol station data -> it is now a much simpler task of finding out what has changed by comparing to third party data thus allowing mappers to hone in on relevant areas.If anyone wants to have a go at building something that would be amazing. Similarly we still have the idea of visualising a "crap data" map floating around (e.g. map of Lloyds TSB, map of Total petrol stations, BHS etc..).
FHRS is certainly a good way to keep on top of changes, and in fact you can already use my FHRS/OSM comparison tool [https://gregrs.dev.openstreetmap.org/fhrs/] to view fhrs:id tags that don't currently match an establishment in the FHRS database, such as an establishment that has closed down. You can look out for red blobs on the map (which may also be matched OSM entities with mismatched/missing postcodes) or examine the table with the heading 'Mismatched fhrs:id tags'.
Hope it's useful. Thanks, Greg -- Twitter: @gregrs_uk http://gregrs.dev.openstreetmap.org PGP key ID: 64907C8A Fingerprint: EBD1 077F CCDD 841E A505 3FAA D2E8 592E 6490 7C8A
