The sixth Interoperable Europe Community Talk, dedicated to the LEOS and EDiT tools, was scheduled for Tuesday, 1 September 2026, from 10:00 to 11:00 CET, online on Webex. The editorial packet stated 29 September; the official event page, updated in August 2026, fixes 1 September. This article follows the Commission source, not the incorrect calendar.

LEOS (Legislation Editing Open Software) is an open-source editor for drafting and reviewing legislative acts in an interoperable XML format. EDiT is the European Commission’s internal collaborative drafting environment, built on LEOS. Presenting the two does not mean compulsory adoption in every administration.

The Community Talk series, which began in January 2026, brings together public-sector practitioners, interoperability experts and community members. The sixth edition, announced by Martina Albini, focused on collaborative legislative drafting.

Interoperability matters when institutions use different systems but must exchange documents without losing structure. Standardisation can support the traceability of changes. LEOS code is available under the EUPL licence for administrations to adapt.

An earlier LEOS community webinar noted that the Commission instance has, since early 2025, been used for a subset of acts in the ordinary legislative procedure. Those figures are not extrapolated here to every EU institution.

Interested readers should check recordings or materials on the Interoperable Europe portal. No outcomes of the 1 September discussion are invented, and no 29 September repeat is announced without a new confirmation.

The acronyms LEOS and EDiT stay explained at first use; they are not a single commercial software package under one name.
