Re: [OSM-dev] OSM API lookups to complement minutely diffs?

[Stefan Keller]

Thanks mmd,

As said, I'd like to fetch the latest available augmented diff and
keep uptodate.
So, to understand it correctly:
Every minute I first call the
http://overpass-api.de/api/augmented_diff_status which returns an id,
e.g. 2111988,
then I fetch the augmented diff file
http://overpass-api.de/api/augmented_diff?id=2111988
Just want to be sure that this is the correct way to use the API.

[OSM-dev] Trouble editing in wiki.openstreetmap.org

[Jonathan Schleuss]

Hi gang,

Sorry if this isn't the right listserv: but I have been having trouble posting 
to the OSM wiki for months.

I've been using Chrome 53.0.2785.116 on a Mac. The problem is a I can't see the Captcha 
to post or save a page I've edited. I see the text saying, "Your edit includes new 
external links. To protect the wiki against automated spam, we kindly ask you to type the 
two words you see in the box below:" but there's no box.

Any ideas?

Thanks for the help (maybe I'm missing something really simple).

Re: [OSM-dev] OSM API lookups to complement minutely diffs?

[Pierre Béland]

I have already opened a Overpass API Github issue relatd to a restriction with 
the Overpass Api while extracting the Attic data. If many versions of an object 
are available in the time span you specifiy,  the Overpass API will only return 
the first and the last versions of the object.  Then, you wont obtain all 
content included in the minutely diffs.

This sounds a lot like what achavi is doing right now.

Note that with the introduction of the famous 'attic' concept, augmented
diffs are nowadays simply translated into a plain Overpass QL query and
calculated on the fly.

This also means that you don't have to stick to a minute interval or a
global scope as before: you're free to provide time intervals matching a
changeset (like achavi does), or restrict the adiff to a certain
bounding box or even some nodes/ways/relations with certain tags only.

There's no XSD around, the wiki page should answer most questions,
though. In general, the Overpass Dev list would be a good place for more
details and discussions. [1]

Ah, thanks. Should have caught that from addr:housename in the default
style file. I had made it more complicated in my mind than it needed to be.
Looks like that will work for my purposes.
