The Office of Management and Budget has posted the second version of the Federal Enterprise Architecture Data Reference Model.

The new standard will make it possible for federal agencies to exchange information; for example if the National Highway Traffic Safety Administration needed to exchange data with the FBI. This is will improve the efficiency and effectiveness of the Federal government.
It will also change the IT industry. Everyone who wants to sell to the federal government will have to comply with this standard. States will put it in their requirements, partly because they need to exchange information with the federal government, but also because they look to the federal government to provide leadership on this sort of thing.
Any company who exchanges information with the federal government, as in an investment bank sending information to the Securities Exchange Commission, will want their software to comply with the standard to facilitate the exchange of data. And so on and so on down the IT economic food chain. The Federal Enterprise Architecture Data Reference Model is the de facto industry standard.
