The Library of Congress is sponsoring a set of legislative data challenges to advance the development of international data exchange standards for legislative data. These challenges are an initiative to encourage broad participation in the development and application of legislative data standards and to engage new communities in the use of legislative data. Goals of this initiative include:
•    Enabling wider accessibility and more efficient exchange of the legislative data of the United States Congress,
•    Encouraging the development of open standards that facilitate better integration, analysis, and interpretation of legislative data,
•    Fostering the use of open source licensing for implementing legislative data standard.

The Markup of US Legislation in Akoma Ntoso Challenge invites competitors to create representations of selected US bills using the most recent Akoma Ntoso standard. This work will help identify gaps in the Akoma Ntoso framework or US bill text where data cannot be incorporated properly within the existing standard, and propose new domain specific metadata elements or possibly other solutions to overcome these challenges.

The winning solution will win $5,000 in cash, as well as opportunities for promotion, exposure, and recognition by the Library of Congress. For more information about the prize, please see the Official Rules.


You may participate in the Challenge if you are:

  • at least 18 years old at the time of entry; you may enter both individually and as part of a team or organization;
  • a team of individuals where each team member is at least 18 years old at the time of entry; and
  • any for-profit or non-profit organization.

A team or organization must appoint a representative to act on its behalf. 

Please see Official Rules for full eligibility information.


Submission should include:

  1. Title of your solution
  2. Executive summary
  3. Converted bill text - data files and supporting documentation for conversion of the text of the four U.S. bills, including the Akoma Ntoso XML versions of each bill.  
  4. Documentation about decisions you made regarding the tools used and processing of data files. 
  5. Open Source Toolkit - if you develop a toolkit for this challenge, it should be included in your documentation and either submitted under an open source license or committed to the public domain. If you use existing tools, we'd like your evaluation of the tools and information about how they were used for the challenge.
  6. Optional Video demonstrating your solution, or describing how your proposed solution would work.

Please see Official Rules for full submission requirements.
