Build a graphical application with Qt and Rust. Qt is a mature GUI library. Rust is a new, exciting and strict programming language. You can build most of your application logic in Rust and write the GUI in QML or Qt Widgets.

This talks will walk through how to do this with Rust Qt Binding Generator.

In this presentation, I will talk about the current developments in OpenDocument ranging from adoption, implementation, documentation, validating and testing by producers and consumers of ODF software and how they help overall software freedom.

It has been more than ten years since the first specification of the OpenDocument was published. The current version, ODF 1.2, has been widely implemented and adopted. Across the world, governments, businesses and people have chosen ODF as the preferred file format for editable documents.

Over the years, many software projects have added ODF support. Not just notable FOSS projects such as LibreOffice, Calligra, OpenOffice, AbiWord, Gnumeric and WebODF, but also proprietary offerings such as Microsoft Office and Google Docs support ODF. The ODF community has held many so-called plugfests and developed a methodology for testing interoperability.

Now is a good point to look at the current state of ODF and what direction it should go in. ODF 1.2 is very rich with OpenFormula, RDF and MathML. Should more features be added? ODF is meant to make exchanging office documents easy. Has this goal been achieved or is there more work to do? Or should we put more effort into perfecting the interoperability between the current implementations? And what is the future of ODF on the web?

In this presentation, I will talk about the current developments in ODF ranging from adoption, implementation, documentation, validating and testing by producers and consumers of ODF software and how they help overall software freedom.

Jos van den Oever represents the Dutch government at OASIS. In 2015, the Dutch government has joined the ODF Technical Committee that specifies ODF. So far, the specification was mostly directed by the software implementors. The increased involvement from organizations that use ODF software shows that this important open file format is becoming more mainstream.

Open Document Format has been tested at so-called Plugfests over the years. At these plugfests compatibility between ODF implementations is tested. This started out as a manual process with a wiki and USB sticks. ODFAutoTests have increased the amount of testing that can be done at a plugfest. More testing could be plugfests lasted longer. To make that possible, a web server is being developed.

The web server builds on the ideas of OfficeShots and ODFAutoTests. The current version is implemented in Haskell with the Yesod framework. The talk will go into the workflow of testing and how it can be implemented in a web page.

Good software can take a hit. Most software can't. The OpenDocument Format (ODF) specification is quite large and very important. Now that it is being adopted more and more, many strange and wonderful documents will be created by custom software that claim to be ODF documents. The ODF softwares of the world should be prepared. That's why ODFAutoTests helps you to create outlandish documents and lets you run them through your software.

This talk will include an enticing argument for writing tests and will present the audience with the data of running the current tests on the current software.

WebODF is an office suite for both local and cloud use. It works anywhere there is a browser or a browser widget. With WebODF you can edit office documents, share them, or publish them. WebODF is compatible with LibreOffice, Microsoft Office, OpenOffice and others, but can also be used stand-alone. It requires no special server software; it can be easily integrated with any web software.

Since WebODF started in 2010, it has grown in many directions. The new breakthrough feature is document editing. No other software makes it so easy to add office document editing functionality to your application. Not only did we add document editing, we added document editing for groups (collaborative editing). Good software is easy to use and packed with features. That is why we made viewer.js. It makes it easy to publish PDF and ODF documents on your website or display them in your content management system. In this talk, we will demonstrate all these exciting new features and explain how you can use them in your software.
