Open, accessible government data really seems to be hotting up.

Last week, the White House launched Data.gov, a website that promises to "make a broad array of U.S. Government data available." Also last week, Vancouver City Council passed a motion (PDF) to endorse the principles of "making its data open and accessible to everyone where possible, adopting open standards for that data and considering open source software when replacing existing applications."

Vancouver's announcement follows in the footsteps of other North American cities like Washington, D.C. and Toronto.

This Wednesday, Nora will interview Andrea Reimer, the Vancouver city councillor behind the open city motion. They'll talk about the costs and benefits of open data, how it can affect civic engagement, and the privacy and security concerns Vancouver will have to consider as it opens up its municipal data.

The interview is slated to run on the June 3 episode of Spark. If you have questions about open data for Coun. Reimer, leave them in the comments below.
