[Legal-general] Do we need an extra server at all...?

[Sunburned Surveyor]

I had imagined it would work something like this:

I'm interested in a PD map for my portion of the world. I cruise over
to the OSMPD data repository and see what is available. If there isn't
enough data for my map, I break out my GPS receiver, if there is
enough data: Woohoo!

I really don't see a practical way to suck OSM SA data back into the
public domain. Really the data flow can only go one direction:

OSM PD Mapper > PD Repository > OSM

There is really no direct benefit to PD mappers of uploading data to
OSM. I think we do it because we want to be good members of the
community, and because it keeps us involved in the overall OSM
ecosystem. I think other OSM mappers will be drawn to OSM PD,
especially those from organizations or companies.

Sure, our repository will have "holes", but it is going to be a work
in progress, just like OSM itself.

The trickiest part of this whole experience will be getting a tool
chain set up that can upload our PD data without overwriting existing
share-alike data. I may be able to help with that...

Do we have any other Java programmers among us?
