Hi Aly,

Thanks for the kind words about OpenMissouri. We'd love it if groups in other locales launched their own data catalogs. In fact, we made our software available as an open-source project on GitHub, so developers can deploy it elsewhere and contribute to the code. (Go here: https://github.com/OpenMissouri/OpenMissouri).

The Sunlight Foundation had been developing the National Data Catalog for U.S., state and city data, but they discontinued it earlier this year. I'm unaware of any similar efforts.
