Cornell's Legal Information Institute
Releases Complete US Code as Dataset
October 8, 2004

Cornell Law School's Legal Information Institute has announced the release of a new online edition of the United States Code, including all the Federal law passed by Congress currently in force. For the first time, the project team is also releasing the underlying XML version as a dataset for use in research.

The XML data set has been generated from the most recent official version made available by the US House of Representatives, codified under fifty "titles". The United States Code "is the official compilation of the Federal statutes of a general and permanent nature; by Federal statute, the Law Revision Counsel of the U.S. House of Representatives is the publisher and compiler of the Code, and the Counsel is an appointee of the Speaker of the House."

Thomas R. Bruce, Director of Cornell's Legal Information Institute (LII), suggests that this edition of the United States Code represents perhaps the largest body of legislation ever made available online in XML format for use by researchers interested in legal text. One of the goals of the US Code project is to stimulate interest on the part of the research community in working with legal text, and to survey the uses to which people put XML versions of legislation.

According to the LII's USC Bell Code Browsing Environment User Guide, the Institite is sponsoring a "continuing effort to render the United States Code as an open-source multi-use XML data set. An important part has been to develop an environment to make the raw data, and emerging interpretations of it, as visible as possible in an analytical mode. As this is primarily a laboratory artifact, not many user friendliness features have been implemented; the emphasis has been utility for someone who knows the project."

The US Code supplied to the Legal Information Institute "is marked up for typesetting; [the project team] uses this specialized markup to help discover the structure to motivate more generalized XML elements. In a preliminary micro-translation, the control-code based input is rendered in a quite literal readable format, which is then stored as a file with the same scope as the input (title or appendix) as well as fragmented along data-natural boundaries and rendered as static HTML for easy viewing."
