[OSM-legal-talk] Effect of Remapping on Contributor TermsAcceptance (Numbers!)

Sun Sep 25 14:16:02 BST 2011

Simon,

Please respect the mailing list charter. You may

contest my irony, but refrain from qualifications as "silly"

If you don't agree, you may say so in normal words.

We know all that extrapolations are not reality, but

your numbers do suggest conclusions like mine.

Again, without Irony this time....

(Limited to nodes only for sake of comprehension: )

Simple calculus suggests that  208'518 / 32'505'411 is only 0.64% of the NO-voted

data, and simple calculus suggests that it takes 155 quarters to fix that in this pace.

If the CT-unknown-voters may in the end all be convinced to CT-yes-voters

that will solve only 25'315'574/32'505'411 = 43% of the

whole non-compliant data set (again, nodes only).

Interesting is data also to notice that 288 single CT-NO-voters have contributed

approximately 128%  amount of node data as the 60K  CT-unknown-voters all together.

(other data approximately equal).

I am really curious to what kind of math you have resource to in order

to qualify this pace as "quite noticeable" and how your math

 resolve all of this in roughly 2 years without effort.....

And has anyone come up with a campaign yet to fix all this ?

How Simon , do you intend to increase the re-mapping from

0.64% to for example 10%  ( 20-fold) , and it will still take

the community 2 ½ year then.

And for contacting 60K mappers, will the community

just ignore their opinion and declare them CT-compliant

by default ? Or will their data be deleted after 2 ½ years ?

Hey OSMF, we need steering here !!!!!

The numbers -only- show the effect of remapping, currently the far larger effect is acceptance of the CTs by mappers who haven't done that up to now. Around 0.1 to 0.2 % per month (depending on the object category). In other words, using just as silly extrapolations as you do, we would have 100% of everything anyway in roughly two years if we simply just let things carry on as they are now (which is not the intention).

It seems as if the community is not that motivated

to re-map  all those evil CC-BY-SA data  that 

sneeked into into the future OdBL fork.

In this pace we need more then 7 years to fix it.

Common CT-OSM members, start mapping all

that misleading non-CT data ! Someone

may use it in a routeplanner and drive

by accident  into a CC-BY-SA road, and

who knows what happens then.

[Apologies in advance for the HTML formatting]

As you may have noticed, the sysadmins were kind enough to generate a new full history dump over the last couple of days. Besides generating new numbers for odbl.poole.ch (which will take some time for the full set), I was mainly interested in seeing how large the effect of (intentional or not) remapping has been over the last three months.  

As can be seen from the following numbers, while the effect is not particularly large (nobody has really called for aggressive remapping yet) it is quite noticeable.

Note: both set of numbers (from the 19th of June and the 19th of September) use the same licensing state data from the 22nd of September. The "Mappers" row reflect the change in the number of mappers that created objects that are still visible in the database.
