I personally gathered some data portals managed by city-level governments into a Google Spreadsheet. Since I have not had time to enter those into DataPortals.org, this can also be considered as a kind of a backlog, which is similar to one by @Stephen.
Feel free to update and add comments on the sheet.
I’m not sure that @rufuspollock’s suggestion of a one-time merger is the best approach. I suspect that with lists like this, the info goes out of date fairly quickly, so having a framework in which responsibility for maintenance is delegated to local groups might be sensible. Personally, I would rather have a system where I continue to be responsible for keeping the Scottish data portals info up-to-date, but adopt a metadata scheme that’s compatible with http://dataportals.org/ and let the data be aggregated there automatically.
@ewan_klein i wonder if we could merge into one place if we had an easy and reliable way to contribute and were able to pull out data portals more easily - e.g. to just display the scots ones. What do you think?
@jgkim@ewan_klein also what do you think of moving to have data portals database stored as CSV in github?
I’d also recommend making systematic use of pull requests by contributors to update the database, though this presupposes that there are enough editors available to review and merge in a timely way.
