LibreItalia Conference 2025 in Gradisca d’Isonzo

Libreitalia Conference 2025 was organized by Marco Marega – a LibreItalia and TDF Member – in Gradisca d’Isonzo, near the border with Slovenia, in Gorizia’s province. Gradisca is a very nice fortified city surrounded be beautiful parks. The conference venue was the historical Monte di Pietà palace, that the municipality administration kindly allowed to use. Gorizia, the administrative center, is a city divided in two parts, half in Italy (Gorizia itself), and half in Slovenia (Nova Gorica). Together, they are the 2025 European’s Capital of Culture. The conference was very interesting, with members coming from many different cities. Furio Honsell – a councilman of Friuli Venezia Giulia region and also a former mayor of the city of Udine and rector of Udine University – was the special guest, introducing his regional law proposal to promote free software adoption in local administrations. Italo Vignoli had two talks, one about the end of Windows 10 support and the other about the 20th anniversary of the ODF format. Marco Gaiarin had a brief talk about good practices for free software adoption. Giulia Bimbi spoke about Italian laws regulating free software adoption in public administrations.

The artificial complexity of OOXML files (the PPTX case)

This is the third and final post on the topic of the artificial complexity of the OOXML format. This complexity is the result of careful design aimed at preventing interoperability. Developers have to deal with a veritable “maze” of tags, even for the simplest content. This binds users to the Microsoft ecosystem, providing the first example of standard-based lock-in. The PPTX case To demonstrate the difference in complexity between Impress and PowerPoint XML schemas in ODF and OOXML formats, I created a simple eight-slide presentation summarising the most common types: title and subtitle, centred text, bulleted list, table, vector image, photo, colour graphics and video. I created the same file using both software programmes, starting from a basic template without a background to prevent interference with the slide format and, consequently, the XML schema. This is the PDF file of the presentation (the first seven slides are identical, while the video on the last slide is replaced by a static image): To perform the analysis, I duplicated and renamed the two files, replacing the original extension with ‘ZIP’, and then unzipped them to create two folders containing all the files from their respective XML schemas. The LibreOffice folder is very
