wish list fo the next yearwish list fo the next year

• Open Government Data as a Right

• More Schemas (Knowledge APIs) – keep it focused, let’s not try to boil the ocean

• Open Data as a Platform, Not a Commodity

• Massive Interconnection Between Open Data Sites

• Open Corporate Data (for and by Corporates)

• Standards (e.g. for catalog metadata) for Data Portals and Data Hubs

• Open Data for Growth – making clear the the connection

• Strong international norms for data inventories

• Organizational identifiers – Dunn & Bradstreet should be replaced with open data

• MiData – getting personal data out of corporates and government back into the hands of the people whose data it is
