Dear OSM-Develpoers,

New extracts are now online, including the requested Amsterdam extract:

They are in a slightly modified PBF-Format that supports the visible 
Flag [1].

They can be read using this modified version of osmium [2] and its tools 
(ie. osmium_convert [3], which allows you to convert the file back to xml).

If you need help reading those files, don't hesitate to ask me.

It has been created using my history-splitter [4] which is build using 
this very cool library.

To generate those dumps I first used osmium_convert to create a 
pbf-bersion of the full-planet-110418-0000.osm.bz2 (I'll publish this 
file soon). This conversion took 8 hours.

 From this pbf file the actual split took just 1 hour (compared to the 
21 hours when I was writing to .osm.bz2 files!!) - what an incredible
