Federal Register
The Daily Journal of the United States Government. One of the difficulties for anyone seeking to use government data is to match up datasets from various Federal sources. Identifiers such as field names and agency name references often are not identical. Federal Register data originates with the files used to produce the print and PDF editions. During the publication process these are transformed into bulk XML files made available by the Government Publishing Office (GPO). Additional MODS files that contain metadata about each document are also produced at the same time.
