Try process:

Elizabeth II Court East
The Castle

"The Castle" will be lost. How come?

[Floppy]

Interesting; is it a street, or a locality do you know?

[giacecco]

Well it's the building where we're hosted for the event. I guess The Castle is supposed to be the street-equivalent, where Elizabeth II Court East is the PAO. @murraydata what do you reckon? Is this one of those examples where the address model we're using shows its limitations?

[Floppy]

Interestingly, 'The Castle' doesn't appear to be a street. That might be what's confusing it. If it can't find a valid street at all, then it probably breaks.

[pezholio]

Yeah, my guess is that The Castle is a non-vehicular street, which aren't in OS Locator. Maybe OS OpenMap will give us better coverage

Hiya, I did a little digging on that address.

The Castle is the name of the building. The street is called Castle Avenue. I was able to find the street on OpenStreetMap (http://www.openstreetmap.org/way/19791923) although as @pezholio rightly points out - it seems to be a non-vehicular street.

I did a quick lookup (below) to confirm that OS Locator does not have a Castle Avenue for the vicinity inferred from the postcode.

FYI, Google Maps isn't aware of the street's existence either.

This may be fixed when we can get access to OS Open Map, as I think their data is richer, but for now, there's not a lot we can do

[peterkwells]

We could but it needs the platform to be able to learn address building blocks from data received through APIs, although with lower confidence than address building blocks gathered from authoritative reference data.

That learning is the ultimate goal of the collaborative maintenance model.

[pezholio]

Oh yeah, totally, but that's out of scope, at least for now. It's a nice thing to aim for, but not something that can be achieved in the short term.
