DITA-OT Day Conference – Rotterdam 2022 November 13, 2022 in Rotterdam, Netherlands. DITA-OT Day was not held in 2020 or 2021. Making the migration leap: jumping across versions to the latest DITA-OT - Robert D. AndersonMany DITA-OT implementations are unable or unwilling to move off of obsolete versions. Some shops continue to run version 1.8.5, released 8 years back (and 15 major versions behind the latest). Why is that the case? What is preventing teams from moving to a more recent, full featured, and supported release? In this session we will discuss what’s involved in moving off of older releases from 1.x, 2.x, and now early 3.x. Most importantly, is it worth it? What would you get from upgrading? When you decide to move, should you go one version at a time, or jump to the latest? Attendees who have gone through this migration in the last few years are encouraged to discuss their experience; attendees who are still running older releases are likewise encouraged to discuss their concerns or share any upgrade plans.Avoiding duplicate effort with post-preprocessing - Tim Grantham If you have publishing requirements, such as custom styling or content restructuring, that applies to multiple outputs (such as PDF and HTML), use post-preprocessing to restructure content before it heads further down the pipeline.DITA and Markdown and Docker, oh my…Nokia’s Cloud and Network Services is one of three major business groups in Nokia, all of which use DITA and DITA-OT for the great majority of customer-facing documentation. Unlike Nokia’s Mobile Networks or Network Infrastructure groups, CNS focuses entirely on software for both cloud and core network solutions and services. With the advent of co-authoring between DITA content from Technical Writers and Markdown content from R&D developers, Lw-DITA and the Lw-DITA OT-plugin have now become key aspects of our documentation ecosystem. The CNS User Assistance Tools team has implemented a dozen OT Plugins, and leverages Ant, Maven, Git, and Jenkins plugins to support both local documentation builds on writers’ workstations as well as CI builds on a server farm orchestrated by Kubernetes. By packaging our Maven, Ant, and DITA-OT customizations into separate Docker layers, we're able to allow R&D pipelines to build the corresponding documentation during a software build to support rapid CI/CD deployments going forward. With the generation of OT Project files by our pipeline, we were able to further eliminate the need for some of our previous scaffolding. Local workstation builds are facilitated by OxygenXML SDK plugins to marshal writer configuration info to OT. Unit testing of our OT customizations is accomplished using a combination of XSpec, AntUnit and Jenkins. The next wave of OT plugins will support OpenAPI3 conversion to DITA in a pre-process plugin and to Markdown. We will also be enriching our content to better support modern presentation solutions, including the application of machine learning and AI-assisted solutions.Scaling the DITA Open Toolkit for Enterprise Use - Robert AndersonModerated discussion about scaling the DITA Open Toolkit for use in big companies.Simpler custom PDFs - The user perspectiveMany tech writers find it hard to customize the DITA Open Toolkit’s default PDF output. Even relatively minor adjustments require knowledge of XSLT, attribute sets, DITA-OT plug-ins, and a bit of research to figure out what you need to change. What if there were an easier way? The DITA-OT project team has been working on an alternative mechanism that can be used to configure basic formatting in a simple plain-text theme file. This approach makes it easier to adjust page sizes, headers and footers, and various attributes for common elements. While complex customizations would still require a custom plug-in, if you just need to tweak a few font families and colors to approximate your company branding, this new alternative might be all you need.Simpler custom PDFs - The technical detailsTechnical description of how the new theme plug-in processes theme files to produce PDF output. We go through how code generation is used to produce XSLT templates that build on PDF2 processing and how that allows us to produce PDFs without coding XSLT. No prior experience with PDF2 customization is required.Various DITA publishing ideas experimented on the Oxygen XML Blog - Radu CoravuI will discuss about various articles we wrote on the Oxygen XML Blog in the last years about various ways to enhance DITA publishing: Generating Google Structured Data Generating content for the Google Chatbot Converting OpenAPI to DITA content Showing consecutive codeblocks in separate tabs Generating an RSS feed Tagging certain articles with labels Embedding diagrams in DITA content Creating Link Graphs From DITA Maps Publishing DITA Content Using the MKDocs Web Site Generator and others.Pushing square pegs into round holesTopic based structured writing doesn’t require DITA or XML. It can be done with a pen and paper. What is required, however, is a lot of discipline. What happens when people are sold an authoring format that allows you to write DITA and that technology will not hold your hand and help you to stick to the rules and guidelines? A description of what happens in one DITA processor when it’s given something that is not DITA but the user really, really wants it to work.Extending Doctales reveal.js with CSS Grid - Lief EricksonThe Doctales plugin creates web presentations using the reveal.js framework. By default the reveal framework does not support CSS Grid or viewport overflow. I'll cover how I extended the XSLT in a new plugin and added a new theme with CSS grid and other features using SCSS.Supercharging DITA-OT Webhelp creationDITA is all about reuse, but when it comes to publishing, none of the existing output makes it into the new publication. In this lightning talk, I will demonstrate how Webhelp (or any HTML-based) output creation can be made 1000 times faster by only recompiling the DITA files that have changed. Using technology that existed even before the birth of XML in a way that nobody has tried before. Conceptual talk, but including proof of concept with fully working demo. Fasten your seatbelts before takeoff.Our experience helping the DITA-OT project as a commercial company - Radu CoravuI will cover the various ways in which Oxygen XML Editor tries to help the DITA Open Toolkit project (by adding issues, opening pull requests, adding documentation issues, helping people with DITA OT related questions on various channels, attending in the DITA OT meetings and sponsoring the DITA OT Day events).DITA HTML Styling via Bootstrap 5A code walkthrough of the updated html-bootstrap plugin demonstrating newly supported components and accessibility options, and discussing the challenges of mapping DITA to structured HTML using XSL transforms.
