My last blog post about the growing agreement to the new CTs is now nearly three months ago. Time for a short update: During the aforementioned time frame, about 32 contributors accepted the new CTs every day. Overall this means that since October 21 2010 there are about 43 contributors each day who accepted the new CTs. I updated my diagram with the latest numbers:

In December I conducted an analysis about the “Change of OSM object numbers through relicensing”. This time I only declared the last modifier of an OSM object (node/way/relation) as the owner of the object! The last and the new results can be seen in the following diagrams:

In my OSM-user-database of March 9th, 2011 a total of 120456* members are the “owners” of the following OSM objects (* Notice: Not every member of the OSM project (>350000 members) has contributed!):

• Number of nodes: 1007604532
• Number of ways: 85365727
• Number of relations: 899145

As of March 9th, 2011, 8124 Users have accepted the new license. 35678 new OSM members (uid >= 286582) have accept the new contributor terms automatically. I created the following numbers of OSM objects, which will be available for relicensing (if you assume that the last modifier is the owner of the object):

• Number of nodes: 801700665 (79,56%) (as of Dec. 15th, 2010 it was 66,52%)
• Number of ways: 66236798 (77,59%) (as of Dec. 15th, 2010 it was 61,68%)
• Number of relations: 716130 (79,65%) (as of Dec. 15th, 2010 it was 62,14%)

Are you still interested in any analysis regarding this topic?

thx @ Dennis

[Update – March 24th, 2011]
The following diagramm shows the above numbers of March 9th, 2011 in percent:

In the past I did some blog posts about the “Growing agreement to contributor terms” here and here. Both posts showed the amount of OpenStreetMap contributors who accepted the new CTs every day during each time frame (about 55 contributors a day). I created a new diagram that includes the past four weeks:

Overall for the past month about 57 accepted the new CT every day. This is nearly the same amount as during the months that have been analyzed before. But what does this exactly mean for the relicensable OSM data? Almost 2 months ago I did a post about the “Change of OSM object numbers through relicensing”. At this time there were about 55% of all OSM Nodes and 47% of all OSM Ways available for relicensing (you can find my post here).

I repeated this analysis with the current OSM data: In the first attempt I used the last modifier of an OSM object (node/way/relation) as the owner of the object. During the second analysis I used the creator (version=”1″) as the owner of the object.

In my OSM-user-database of 12/15/2010 a total of 111310* members are the “owners” of the following OSM objects (* Notice: Not every member of the OSM project has contributed!):

• Number of nodes: 878201891
• Number of ways: 73825397
• Number of relations: 790100

(Current status of the OSM database statistics are here)

As of Dec. 19 th, 2010 (16:00), 6076 Users have accepted the new license. 25487 new OSM members (uid >= 286582) have accept the new contributor terms automatically. I created the following numbers of OSM objects, which will be available for relicensing (at the above mentioned date of my data). If you assume that the last modifier is the owner of the object: (the numbers in brackets represent the percentage of the total objects!)

• Number of nodes: 584163816 (66,52%) (as of 10/10/2010 it was 55,89%)
• Number of ways: 45536248 (61,68%) (as of 10/10/2010 it was 47,56%)
• Number of relations: 491014 (62,14%) (as of 10/10/2010 it was 31,06%)

I did the same analysis with a second dataset in which the creator (version=”1″) is also the owner of the OSM object (my table is based on the full-history-dump of October 22, 2010). A total of 109005 members created:

• Number of nodes: 911411022
• Number of ways: 75235513
• Number of relations: 1151219

And the following numbers of OSM objects (version=”1″) will be available for relicensing:

• Number of nodes: 586598103 (64,36%) (as of 08/01/2010 it was 54,24%)
• Number of ways: 44844834 (59,60%) (as of 08/01/2010 it was 46,78%)
• Number of relations: 480370 (41,73%)

Notice: The last numbers of OSM objects could contain deleted objects too. I only checked and counted the version=”1″ of a object. So probably the numbers for relicensing OSM objects (version=”1″) should be smaller!

However, in my opinion the results are interesting enough to publish them here anyway.
Can anyone confirm these absolute numbers?

thx @ dennis !

In my last post in average ca. 38 members accepted the new Contributor Terms (CT) every day. I created a new diagramm which shows the increase of the accounts for the past month.

Overall for the past month every day ca. 55 accepted the new CT.

What causes the increasing support to the new license? Are more people getting familiar with the new license through publicity work? Or is it maybe Fabian´s ODbl-Map?

thx @ dennis

As I mentioned in an earlier post, since October 10th there is a list of OSM member accounts available that have agreed to the contributor terms. The file is available here and it will be refreshed every hour. I created a diagram that shows the increase of the number of accounts in the past.

So for the past 15 Days, in average, about 38 members accepted the contributor terms every day. As you can see in the figure above, there was a problem while creating the users file on the server between Oct. 29 and 31. It seems to be working normally again by now. Remember, new OSM members do automatically agree to the new conritbutor terms, so that they are NOT counted in this list!

However, I think it will be interesting to see if or how a change will be visible in the next weeks (or months?) compared to the numbers from my last post “Change of OSM object numbers through relicensing – Vers. 1” …

thx @ dennis 🙂
