Re unmaintained. That isn't what has been said. The service and site is
maintained and is monitored by sysadmin. As set out in the Roadmap we are
not prioritising fixes to the loading system as we want to move to the new,
In any case, delighted you are looking at flat-file stuff and could this be
contributed as part of the Roadmap for OpenSpending "v2" platform.

Sounds interesting. Again, would it be worth seeing if this can align or be
part of the aggregation system for OS v2. Early stage outline at:

Interesting to see how this goes then.

One blunt question: are you basically intent on forking here are you doing
this as part of a way to continue to contribute to OpenSpending "v2"?
