[OSM-talk] licence plan - Question about supplying own data

[Jason Cunningham]

Hi All

I've read through a bundle of licence emails, and there is one aspect that
worries me, which hopefully someone can clarify.

>From my understanding (and I dont speak legalese), under the CCBYSA license
you can take OSM data, create a "derived work" and distribute it. But, you
had to let people know you where using OSM data, you had make it clear that
other people where allowed to use your "derived work" to make further
derived work and the CCBYSA licence must apply to their work. But its turned
out this license may not be enforcable. A new licence has been proposed that
is enforcable, but adds a significant new "obligation" to people/groups
creating derived works.

Looking through advice regarding the new or proposed licence in the wiki I
have come across the following which I am worried about and wish to clarify
(which I quote below)
1. http://wiki.openstreetmap.org/wiki/Open_Data_License_FAQ
"requires those that combine our data with their own data will have to give
the latter to OSM. This means *we get more open data*."

2. http://wiki.openstreetmap.org/wiki/Open_Data_Licence/Use_Cases
"*Section 4.3 also requires that the notice include information regarding
where the user can obtain a copy of the Database or Derivative Database.*"

So it appears under the new licence when I create a map using OSM and add my
own data (derived work), I have to make my data available to OSM. This leads
on to a couple of questions.

*Questions*
1. *The main question*. Do I (any one else affected) have to actually send
my data to OSM, or, make sure its available (via an emailed file (if
requested) or as a download on a website), or, am I simply giving the right
for OSM to to take the derived work and copy/extract all data.

2. I am not entirely happy about making people/groups supply their data to
OSM if they wish to create derived work. I agree with the original principle
within the CCBYSA, that the derived work had to be CCBYSA. But I feel
demanding that individual/groups make the data available puts a burden on
some people they can not meet, or will not be acceptable.
eg

   - (extreme example?) A group of 8 year old kids spend a day in a local
   park mapping out locations where they find butterflies. They map this
   information using an OSM map and stick a copy on their local parks
   noticeboard. Surely they shouldn't be made to make this data available to
   OSM? Its not worth the bother for them (or OSM)
   - A wildlife group wishes to map the location of endangered species.
   Lacking money, OSM seems like a good resource, but they* *can not supply
   the data and therefore the location of protected species to OSM. So they can
   not use OSM and have to spend money on another map?

I started supplying data to OSM in the belief I was creating map data that
was free and could easily be used by everyone. This can not be achieved if
the burden of using OSm data is greater than the benefit.

Cheers

Jason
