It goes away. All objects get rolled back to the last valid state
that have no unlicensed edits before them. So any object where v1 is
unlicensed is gone, no matter how many changes have been done to it
since.
Surely that can't be correct? For example, I've surveyed an awful lot of
the
Perth northern suburbs, but I started off by tracing Nearmap imagery. My
understanding is that Nearmap haven't agreed to the new licensing but
nevertheless I've since personally surveyed the streets, corrected
alignments, added names and changed "source=nearmap" to "source=survey".
I would understand if data and records of the original "source=nearmap"
disappeared with the license change, but the subsequent "source=survey"
edits would be able to be kept? Dropping data simply because at one time
it
was in an incompatible-license state but is now no longer sounds
incredibly
destructive to me.
As I understand it the position is potentially far worse than you outline
above.
Individual bits of data won't be dropped because at one one time it was
sourced from Nearmap. ALL your data will be marked as non-compliant if you
cant agree to the CT's.
This is why in my situation the relicensing per changeset would be so
useful. It allows the >80 % of my contributions to be marked as CT/ODbL
compliant.
However, as yet I am unclear what actually happens to data which has been
entered by a user account which does not agree to the CT's. (see below)
Is what's going to happen documented anywhere? I've had a poke around the
wiki, but can't see anything relevant to how the data is being handled.
The nearest I can see to an "answer" is in the paragraph relation to phase 4
of the implementation plan [1] ; "What do we do with the people who have
declined or not responded [to agree to the CT's]? Their contributions would
not be available under the future ODbL version of the database". Which
presumably implies that all their data, and anything based on that data will
be removed from copies of the planet files, and will no longer be shown when
using any of the editors.
I presume that some time in the next 7 weeks (ie before 31 March 2011) it
might be made more apparent what will happen, since in order for an ODbL
complaint database to be available on 1 April I trust that someone is
working at the moment, not only on the principles involved, but also on the
actual coding necessary.
