The Code of Federal Regulations (CFR) data sets consist of annual editions of the CFR in XML-tagged files. When unzipped, the CFR data packages contain XML files for each of the 50 CFR subject matter titles, encompassing all of the individual CFR print/online volumes that are reissued each year. CFR volumes are published quarterly, with new data sets being added as they become available (see publication schedule and list of titles below).

When Congress enacts laws, or when the President and Federal agencies determine that new regulatory measures must be undertaken, agencies publish the changes in the Federal Register, which are integrated into the standing body of law in the CFR. Many volumes of the CFR are quite dynamic, changing substantially from year to year. For that reason, it is important that multiple years of the CFR are converted to XML. An incident occurring in 2007 would be enforced or litigated based on rules in force in the 2007 edition of the CFR.
These data sets are of high value because the CFR contains all of the general and permanent regulations of the United States government, which affect nearly every aspect of life in the United States. Each citizen has rights, obligations, protections, and benefits under law, specifically defined in the CFR. Federal regulations set enforceable standards for food safety and drinking water, for the air we breathe, for various forms of transport and communication, for our financial and health care systems, for security and national defense, and in many other areas. The CFR was created by a 1938 amendment to the Federal Register Act, which was the first open government law of the U.S. government. In general, a regulatory requirement is not enforceable against any person unless it appears in the text of the CFR.
By making CFR data available in XML, developers will be able to present this complex information in new ways. For example, multiple agencies have responsibility for safeguarding the environment, wildlife, and natural resources. With XML structure and underlying metadata, it is possible to build applications that present regulatory issues geographically, topically, and chronologically, in addition to agency-by-agency. It will also be much more feasible to correlate provisions of the CFR with other legal resources in our information domain, such as proposed regulations and public hearing notices in the Federal Register, the President’s orders and statements, agency programs in the U.S. Government Manual, and the Public Laws that set out the broad regulatory framework and grant legal authority.
Public Access to the CFR:
- can be used to increase agency accountability and responsiveness
- improves public knowledge of the agency and its operations
- furthers the core mission of the agency
- creates economic opportunity, and
- responds to need and demand as identified through public consultation
This is the first time the data is available as raw data in XML format.
