Invisible XML (ixml) is a language and process for identifying structure in documents. Invisible markup allows users to exploit the implicit structures in documents without the need for explicit markup. Since the release of the ixml standard in 2022, we have seen a steady increase in the use of ixml, as well as many interesting conference presentations about the language. The community group therefore feels the time is right for an event exclusively dedicated to invisible markup.
The Symposium will be held via Zoom on two afternoons (Western European time): Thursday/Friday 26/27 February 2026. The sessions will be four hours each day.
Attendance will be free.
Slides will be published on the ixml website after the Symposium, along with videos of the presentations if these have been made available.
