Sorry but Frederik and my numbers (odbl.poole.ch) are compatible (odbl.de naturally not, RTFM). Just because some areas look like a big red blob, doesn't mean that are lot of useful (ie non-imported) data is being lost, look at Spain for example.

The numbers come from Frederik's map and some areas really look dramatic. odbl.poole.ch <http://odbl.poole.ch> and http://odbl.de come to very optimistic conclusions. Possibly because they only consider the last contributor to an object or another metric which doesn't hold water.

    I'm not quite sure where you got your numbers from, but it is
    clear that in terms of outright deletions we are talking of less
    than 5%.

    See odbl.poole.ch <http://odbl.poole.ch>

        That's not the point. Since not making a decision is the same
        as declining for the purposes of data survival, deleting a
        quarter to a third of the map seems to me to be the project
        committing suicide. It will improve no doubt as time goes on,
        but I was seriously expecting the threshold to be in the 90+%
        of data survival to proceed.

        Yes, the 100/1 means that only a tiny fraction of the red and
        orange is ideological, it's surely mostly about people who
        have moved on, in interests, email addresses or mortality who
        we'll just never hear from. If it were just their edits, I'd
        be much less concerned, but it's the way it kills everyone
        else afterwards. It's even more galling when they deleted the
        original data to make their edit, so they've effectively taken
        the earlier work away too.

        I'll certainly be contacting people now Frederick has provided
        an easy means to evaluate the data, but I'm not overly
        optimistic about people replying - I run a membership database
        and find maybe 10% of people change their email addresses each
        year, and half of those don't tell me, and that's when they've
        paid an annual sub to belong.

        Is anyone going to answer the question about the threshold?
        I'm not being rhetorical, I really would like to know.

David
