This document discusses integrating the LEOS legislation drafting software with the ManyLaws legal informatics platform. LEOS allows for online collaboration on legislation, while ManyLaws relates laws within and across countries and translates them. Integrating the tools would allow users to access relevant laws from other jurisdictions, compare legal elements, and create metadata during drafting to make new legislation retrievable in ManyLaws. This would provide a powerful solution for legislation drafting within the EU. The document outlines ManyLaws' process for handling legal data and how LEOS could integrate to directly input new data and access ManyLaws' services.

2. What is LEOS
LEOS - Legislation Editing Open Software, is an open source
software delivered under ISA² Action 2016.38 Legislation
Interoperability Tools – LegIT.
LEOS is designed to help drafting legislation, by facilitating
efficient online collaboration through:
– Comments
– Suggestions
– Version control
– Co-edition
– Restrictive structure
LEOS supports AkomaNtoso metadata schema

3. What is ManyLaws
ManyLaws is a legal informatics platform, result of a CEF Telecom
Action
ManyLaws utilizes high-performance computing, automated
translation and AI to :
– Interrelate laws within a member state legal system
– Compare laws between EU member states
– Interrelate member state laws and EU directives
– Visualize progress and relations of laws
– Translate laws to member state languages
ManyLaws supports AkomaNtoso, ELI and DCAT metadata
schemas
ManyLaws is accessible at www.manylaws.eu

5. Why integrating LEOS with ManyLaws
The ManyLaws / LEOS integration can provide parliaments with a powerful solution for
legislation drafting, so that users will be able to:
1. Create “clusters” of relevant legislation from an EU member state, for any new legislation
that is to be drafted.
2. Locate and cite relevant laws from other EU member states, when drafting new legislation.
3. Locate relevant legislation at EU level, when drafting new legislation.
4. Compare legal elements (e.g. new vs existing) across different domains and countries.
5. Create the necessary metadata when drafting new legislation, so that it is ManyLaws-ready
(automatically retrievable).
6. Make any new legal element OpenData-ready, through also inserting the necessary DCAT
metadata elements.
7. Use ManyLaws to visualize the legislation process, for a new legal element.
8. Coordinate ManyLaws and LEOS thematic ontologies and controlled vocabularies.
9. Use other advanced features of ManyLaws (e.g. sentiment analysis on social media posts
about legislation, intelligent consistency checking on new legislation, automated
translation).
