The timing couldn't be worse.
The Wikimania is starting now and I want to use this event to promote
OSM and WIWOSM. But we can not change it.
So I prefer the first way to be up-to-date with WIWOSM.

After OSMF was originally wanting to start the license change at the
beginning of April, due to technical problems with the redaction process
of non relicensed data, it has been delayed till now.
The OSMF has now announced a new schedule . It will begin removing
data for which it does not have permission to relicense from CC-BY-SA to
ODbL 1.0 this coming Wednesday 11th.
It will happen as a slow process while normal editing of OSM data
continues. From a data consumers perspective the removal will look like
any normal deletion of data and will be mixed in the minutely / daily
diffs with the normal changes. The duration of this process is not yet
clear due to the uncertainty caused by the load of the normal edits, but
very rough estimates supposedly range from a week to several months, but
hopefully it will be completed within a month.
Luckily, worldwide only a little more than 1% of the total current data
has to be removed, but regionally this can unfortunately still be a lot
more despite all the efforts to minimize the impact.
The question now is how should the wikipedia osm-tile-servers handle
1) continue as normal, importing the minutely diffs. This has the
advantage of staying up to date with all the ongoing mapping efforts,
but the disadvantage of degrading the data in areas where the
redaction-bot deletes things.
2) Suspend the diff imports during the redaction phase: This allows
mappers time to fix some of the damage done during the process, but
removes the up-to-dateness of the map.
This affects at least the tileserver run on toolserver.org
tiles for the osm gadget for various wikipedias and the WIWOSM project.
But depending on when the new tileserver run by the foundation for its
mobile project goes into production, it would also need to make this
decision. I don't currently know how the mapquest open tiles will handle
During the redaction period, all data continues to be CC-BY-SA. When the
actual cut-over to ODbL will occur is not yet clear, as the timing of
the redaction bot is still uncertain but presumably very shortly after
it has finished.
