Hola,
Yes, I think it was one of the concerns of the creators of the revised
guidelines to assure that the scattered information on project's
websites like Missing Maps and companies' blogs finds a way back to
OpenStreetMap's infrastructure.
The Tasking Manager is probably the software that is used for most
organised editing efforts. And a lot of the information required by the
Organised Editing Guidelines is already present in the projects'
descriptions and database of the TM. There the idea emerged that the TM
could (automatically) report back to OpenStreetMap. This would make it
much easier to comply with the guidelines. Me too, I don't think the
wiki is a good place for managing this. Following the idea of automated
reporting through the TM, and estimating the amount of projects created
on all instances, I know of, I'm not sure, whether we want the wiki to
have thousands of entries every year and I actually don't know if
automated feeding would work.
However I understand the value to store reporting on organised editing
activities on OSMF's side and in one central repository. I just doubt a
bit about the technology proposed to be used.
Some conversation around that has started here, and I invite people to
participate https://github.com/hotosm/tasking-manager/issues/1373
Thanks,
Felix
