[OSM-talk] To John Bright (unwayed segments to unclassified ways)

[Frederik Ramm]

Hi Peter,

    it seems you have missed a month's worth of postings on the  
subject ;-)

Unordered ways will become ordered one way or the other ;-) branching  
ways will be split.

I have been doing this ever since the beginning of August. I have  
provided a test server, and a working JOSM instance to go with that.  
I have regularly (but not weekly) updated the test server with  
current planet files since then. Gabriel and I have provided 0.5- 
style planet dumps, 0.5-syle database excerpts, and even given  
accounts on the machine running the database to anyone who was  
interested. Almost everyone involved in developing software for our  
"core toolchain" has received a detailed briefing from me by email  
weeks ago.

I will do the conversion one final time with today's planet file -  
this is going to be, or at least it is planned to be, the "dress  
rehearsal" for the 0.5 conversion in which I will also meticuously  
write down time and disk space used for everything, so that we know  
what to expect when we switch.

As I said, this has been going on for about six weeks now and I  
wonder how you could have missed it! It's all detailed on the Wiki  
page (http://wiki.openstreetmap.org/index.php? 
title=OSM_Protocol_Version_0.5) and has been announced by myself to a  
degree that I felt was bordering on spam ;-)

(There aren't very many people using the test server but at least  
those developing software seem to have used the opportunity. And I  
can't really do much more than give people the opportunity.)

We have tentatively scheduled the switch for the weekend 6/7 October.  
Anyone who sees, now or during the next week, a good reason why we  
should postpone is welcome to step forward ;-)

Bye
Frederik
