hi
I must admit that I didn't know that there was a working instance of
TRAPI - I thought it was just a proposal.
How do I connect to a trapi server?
Is there a public server?
I can find a description of the service but not an url.
This is tried:
503 Service Unavailable

Hi,
Am I missing something here...? People are complaining about how bogged
down and slow the current service is, so its being re-written in java?

Let me just explain what I see as the major performance bottleneck
with and API implementation: Disk seeks. A typical computer can
perform a million calculations while waiting for the disk to fetch a
few bytes. So a good data structure that can answer most map (bbox)
calls with a single disk seek

I tend to use xapi to get town or city sized chunks of OSM data, without any
clever processing - would TRAPI be better for this than XAPI, or is it
limited to smaller areas?

It seems there is no XAPI server available for a long time, what's going on ?
Is this service deprecated ?
I think XAPI is very usefull for quick extract using rules, it's a shame we
can't do this anymore...

The demand for XAPI is very high but it is currently only running on one
quite small server, so requests will quite often fail.
The main server, called Fafnir[1], has only 4Gb of ram and low end disk
storage. It's doing the best it can but there is always more demand for
XAPI queries than it can
There is the 5ok MapQuest donation earmarked for this, isn't there?
http://blog.osmfoundation.org/2011/01/26/donation-to-osmf-by-mapquestaol/
Is there a plan already on how this is to be spent? Is the XAPI a priority?
It seems a lot of people like it (I do) so I'd be interested to know this.

More XAPI servers running on good hardware is the only realistic
solution.
Well, there could perhaps be another solution, like running your own
XAPI server - the minutely diffs are usually less than 100Kb, so the
required bandwidth to download from planet.openstreetmap.org would be
less than

Are the hardware requirements really so modest?
A few weeks ago I tried experimenting by importing just Europe and it took a
week (on my machine which has 2GB memory), so I gave up on the idea of
having my own whole planet database.
Then I had major trouble with the database size growing, and

Something I wonder about :
does osmosis/xapi import the planet dump as-is, or does it do some
pre-processing to get rid of the history ?
If osmosis is lossless, would it make sense to make a lossy version that

Yes, you are missing a few things ;-)
