Open Data

The parliament has opened its database for free use. The aim: to make parliamentary work even more transparent and accessible to all and encourage collaborative use.

700,000 items of data for free use

As of the start of the parliamentary year 2022, the Chamber of Deputies has become even more transparent: the Parliament is making a large proportion of its data available for free use.

Over 700,000 items of data from the Chamber of Deputies will be available on the Luxembourg government’s Open Data platform to encourage free use and collaborative re-use. Developers, researchers, journalists, and other interested parties may produce their own applications or statistics on the basis of this data.

To begin with, the Chamber of Deputies made the following data available:

  • the transparency register (since it was introduced in 2022)
  • the list of petitions (since 2014)
  • the list of parliamentary questions (all data)
  • the composition of committees, international delegations, and decision-making bodies (Conference of Presidents, Executive Office) (since 2009)
  • the deputies currently in office
  • former deputies (since 1998)
  • attendance at plenary sessions (since 2018)

Next, by the end of 2022, the following data will be accessible:

  • the list of speeches by deputies (since 2013)
  • votes (since 2018)
  • the list of committee meetings (since 2018)
  • the list of motions
  • the list of government bills/private member’s bills
  • the list of European directives and their transposition into national law

The spirit of the ‘Open Data’ policy is to provide data that goes back as far back as possible. Data are updated every month.

The legal framework

  • The Chamber of Deputies has adopted the principles of Luxembourg’s ‘Open Data’ strategy, launched in 2018. It is based on texts and practices that have existed for almost 20 years.

    In the European Union, the legislative framework of the Open Data movement was created with Directive 2003/98/EC and Directive 2013/37/EU on the re-use of public sector information. In Luxembourg, these directives were transposed by the amended law of 4 December 2007 on the re-use of public sector information.

    A new legal framework was implemented in Luxembourg in 2021, established by the law of 29 November 2021 on open data and the re-use of public sector information.

    This law transposes the European directive (EU) 2019/1024 of the European Parliament and of the Council of 20 June 2019. Access to public documents is covered more specifically by the law of 14 September 2018 on a transparent and open administration.
