A brief reminder that this Saturday 4th December is the international open data hackathon!

It’s a gathering of citizens in cities around the world to write applications using open public data to show support for and encourage the adoption open data policies by the world’s local, regional and national governments.

Head over to the open-government list!

I’ve found a new dataset or cleaned up a dataset. How can I tell the world?

Fantastic! Please add it to a CKAN instance in your country (for a full list see here).

If you are adding an existing dataset (e.g. one that you’ve found on a government website), please go ahead and register it for all to see!

If you’ve cleaned up a dataset, please provide:

  • a link to new dataset

We’d be grateful if you could tag all newly datasets with opendataday2010 so we can see what has been added on the day!
