LEOS-Pilot 2.0.0

About LEOS

LEOS is a software that was created under ISA Action 2016.38 Legislation Interoperability Tools - LegIT to address the need of the public administration and European Institutions to generate draft legislation in a legal XML format.

It is a legislation editor and this current prototype supports the drafting of the 'secondary' legislation of the EU law which has to be adopted under the Ordinary Legislative Procedure. Therefore, it covers the writing of Proposals for Directive, Decision and Regulation submitted by the Commission to the Council and the Parliament. If you want to find out more about this procedure, please read the European Parliament's article.

Given the high diversity of legislative traditions encountered across the Union and the different levels of modernisation, it was extremely difficult to provide a universal single turnkey ICT solution that adapts to each specific context. Even if a significant part of the business logic can be found embedded in the code, we design with the goal of delivering re-usable building blocks so LEOS is released Open Source as we believe that some parts of it could be reused and adapted by some other Public Administration having similar needs. For more information on the features please check out our article here.

The code is available for free under European Union Public Licence 1.2, and the development team paid attention to organise the code in a structured way to ease its reusability (modules, plugins…).  For more information on the EUPL licence, please visit this link.


If you are interested in seeing how this works, what better way than trying it yourself?

Please take into account that some IT knowledge may be required to set up prerequisites and run the demo. Make sure to have all the prerequisites up and running, download the release, unzip it and run the “run-all.bat” file. For more information on how to run the demo please check the README.txt

For more practical information, please check the “LEOS-Pilot_2.0.0.zip\LEOS-Pilot_2.0.0\docs\” folder for the Technical architecture.doc and HOWTO folder and our supporting documents. The team and Mr. Leo S have made sure to make the supporting documentation clear, but if it is not, please don’t hesitate to send us an email at DIGIT-LEOS-FEEDBACK@ec.europa.eu.

What's new?

This Beta version is currently used for a pilot across the Commission services. The main differences compared to the previous prototype version are:

  • Possible to add comments & highlights using annotations.
  • Possible to add suggestions on a part of text with the feature to accept and reject a suggestion.
  • Improved version management, with major versions and possibility to see differences between versions.
  • Improved table of content edition.

What's gone?

This time...nothing :)


Get in touch!

We are envisaging to create an open source community on software for legislation drafting, in order to share best practices, experiences, expertise, and why not code!! Should you be interested or would you just like to share with us some observations on our work, you can join the conversation one legislative drafting here OR contact us at DIGIT-LEOS-FEEDBACK@ec.europa.eu .


We are looking forward to hearing from you,

LEOS Team for LegIT ISA2 Action
