This tutorial takes an eat-your-own-dog-food approach to showing how to use CSS for paged media. Using the HTML text of its own slides, the tutorial session will progressively reveal and explain the CSS styles that are used to format and paginate the slides. By the end of the session, the fairly undifferentiated mass of text will be formatted with running headers and footers, page numbers and page number cross-references, bleeds, CMYK colours, footnotes, top- and bottom-floats, and other features that appear in paged media but not in a browser.

This session will focus on the current state of PrintCSS tools in an informal format. It will provide an overview of the available tools in the PrintCSS domain and compare their features from a high-level perspective. Participants will gain insights into the various options and understand how these tools stack up against each other. The session aims to foster a comprehensive understanding of the PrintCSS landscape and enable attendees to make informed decisions regarding tool selection.

This tutorial aimes to provide a deeper knowledge of the Invisible Markup language ixml, a method for automatically discovering and adding markup to notations. While humans can deduce implicit structure in notations, computers require explicit information. The session highlights how Invisible Markup can be applied to various input forms, such as CSV, JSON, CSS, bibliographic entries, and more, with XML as the target markup language. It explores case studies and advanced usage examples, including the ixml grammar of ixml itself. The tutorial follows a lecture format with hands-on exercises. Attendees should have studied the introductory tutorial beforehand (available online), and will need to bring a laptop to the tutorial.

The XProc 3.0 tutorial will be a mix of theory, demos and practice. If time and technical hurdles allow, attendees can do (simple) exercises to get practice and a feel for the language. The presentation itself is also available.

If you want to follow along with exercises, please perform the preparations for the tutorial as mentioned in mu-2023-xproc.xatapult.com

This session will consist of two parts. Firstly, we will provide an update on the current state of Antenna House software. Secondly, there will be an opportunity for participants to engage in discussions with us and their fellow attendees. We encourage you to share any challenges you have encountered or suggest features that you would like to see.

This presentation explores the use of XProc 3.0 in developing a set of command-line applications for converting XML documents into various derivatives. The author uses XProc as the core of the application and experiments with building the application logic in XProc, including command-line handling and file/directory management. The paper proposes two design patterns that can be widely applied to use XProc effectively in developing command-line applications.

Decentralization of data and applications with edge computing is coming outside the XML community. Can we revitalize web browsers and shift XML processing from the server-side to the client-side with added benefits of improved speed and low-latency? Can we make XML an alternative to Javascript and JSON development within web browsers? This requires client-side database technologies, client-side XML programming languages, support for XSLT, and powerful ways to address standalone XML documents as well as XML stored in document databases or XML supplied through cloud-based API calls. This calls for data abstraction and a unified data model within the web browser. This paper talks about two large projects aimed at solving the client-side equation of XML and put XML on the map for web development again.

This session looks at how easy or difficult it is to format the Markup UK proceedings to PDF using Norman Tovey-Walsh’s XSLTng DocBook stylesheets.

The paper describes an XSD visualizer plugin that automates schema visualization and emphasizes the accuracy and completeness of element structure. It provides a comprehensive view of the inheritance hierarchy and actual element structure, allowing users to quickly identify potential errors and ensure the correctness and completeness of markup documents. This tool is useful for academics, software engineers, and end-users interested in enhancing their markup quality assurance practices through automated schema visualization with a specific focus on element structure.

ISO/IEC JTC 1 is the joint technical committee of ISO and IEC that is responsible for IT standardization. SC 34 is the sub-committee of JTC 1 that is concerned with the active maintenance of several wide-used document description and processing language standards, including the schema language Schematron (ISO/IEC 19759-3) and office file format standards OOXML (ISO/IEC 29500), ODF (ISO/IEC 26300 in collaboration with OASIS) and standards supporting the use of EPUB for e-books. The presentation will include a brief update on the current work programme of SC 34.

The paper discusses the challenges faced in enhancing the quality of XML pipelines. The existing pipelines are based on batch scripts and XSLT. They produce high-quality XML results but lacked additional quality features. The paper describes the additional features that were added to enhance the pipeline quality, such as validating results, verifying links to image documents, and producing only valid transformation results. The paper discusses how XProc 3.0 was used to improve the pipeline, reduce dependencies and enable the creation of summarized logs.

There are established software solutions to convert from XML to TeX. Nevertheless, these approaches either limit the configurability of the TeX output or introduce a lot of programming effort. In this paper, we will discuss these methods and present an alternative approach that hopes to offer the greatest possible flexibility based on fixed conversions, an extensible configuration and the injection of XSLT, and that forms the basis for our Open Source typesetting system xerif.

Interoperability and extensibility are keywords for XML. Why are we not seeing the same for software applications, web applications, mobile apps, and operating systems in general? Why can’t I run an iPhone app om my Samsung TV? Why isn’t Mac applications possible to run on my Windows computer? If we had interoperability and extensibility in a similar way that XML provides for data, but for software, we would not have any of these problems. Software would run across all types of devices, screen form factors, and operating systems – across desktop, mobile, smart TV’s, and the infotainment systems of cars.

This paper discusses how to use the XIOS/3 Edge Application Platform and the CloudBackend Singularity Database to create a new XML- and cloud-based operating system complete with productivity applications, software development tools, and a file system – including extensive support for XML.

While CloudTop XML OS is still under development, this paper provides a snapshot of the current state of the implementation and provides examples on how to build XML-based software applications.

This paper discusses the benefits of using Test-Driven Development (TDD) on XSLT development, specifically using the XSpec unit-test framework. Through TDD, the resulting XSLT code is of high quality with no bugs, easy to maintain, and well-documented by tests with 100% code coverage. The paper also includes a live-coding session demonstrating how to apply TDD and refactoring operations such as Extract Function.

This presentation describes Kurt's journey of replacing WordPerfect with prodoc.dtd, a semantic authoring doctype; and how prodoc evolved to enable computer-assisted sense making, based on markup that formalizes knowledge flow analysis and modelling semantics. The paper also describes some of the challenges associated with multi-perspective decision making and techniques for negotiating and formalizing dynamic, natural-system ontologies. Lessons learned from WordNet and SUMO integrations are summarized. The paper concludes by suggesting that building editors and bots that use author-authored markup to digitize and amplify logic systems could, in many organizational settings, contribute to more-intelligent value optimizations and better long-term performance.

This presentation introduces markup languages from a new point of view, namely handling XML in linguistic terms and tools. Just as natural languages XML languages have their own vocabularies, dialects, and grammars, and get translated into and from other languages during the publishing process. The author suggests that instead of creating ad-hoc linter rules for quality assurance the linguist's toolbox is worth considering. The presentation starts with a reasoned claim on the history of semantic markup (3600 years old!) and climbs the tree of linguistics for fruits from the translatology and corpus linguistics branches. From there he presents a view on the quantitative aspects of document processing and addresses daily XML-practitioners with measures for readability and complexity, citation styles, the benefits of translation memories, and editor macros and techniques from the very bottom of Chomsky's hierarchy.

This presentation aims to give an overview of AI and its potential benefits for content verification and correction using Schematron and SQF. OpenAI, a research lab focused on AI, has developed algorithms that can be used with Schematron to automate the verification of content. This can help save time and money for content creators and publishers while improving content accuracy. However, there are challenges in using OpenAI algorithms, such as the possibility of inaccurately identifying errors and not being able to detect cultural or regional differences in language. It is important to consider these challenges when using OpenAI for content verification and correction.

This presentation will cover XQuery for Schematron (XQS), a Schematron processor being implemented in native - and naive - XQuery. To the author's knowledge, there are no other such implementations available at this time. The purpose of the work is at least two-fold: to demonstrate the utility of an XQuery query language binding for arguably the primary quality assurance technology applicable to XML, and to provide a second "reference" implementation while work on the latest revision of the ISO standard proceeds. (There is no formal requirement for any implementation under ISO regulations, but it clearly helps to be able to answer the question standards authors should consider when new features present themselves: How would you implement that?)

"Markup quality assurance" is the theme for Markup UK 2023, but what does "quality" mean when the markup is meant to be formatted for human consumption? When that markup is transformed from an original document in a completely different XML vocabulary? This presentation looks at different ways of assessing or assuring the quality of both the markup and the formatted document.

Back in 2020, the author outlined some ideas for new features to go into a proposed XSLT 4.0. This talk gives an update on how those ideas are progressing. A W3C Community Group has been formed to take proposals forward and is meeting weekly; the current state of play is visible at qt4cg.org for those who are interested.

Inevitably, there's a vast amount of detailed change, and standing back to examine what's significant, what the overall themes are, isn't all that easy. Perhaps the best way to summarize is to say that we're adding functionality and convenience, all building on the solid foundations of the 3.0/3.1 specifications. In 3.1 we introduced major new infrastructure: arrays, maps, higher order functions; but there's a feeling that it's not fully exploited. For 4.0, the aim is to leave the foundations intact, and to build on them. The talk will aim to have both breadth and depth: giving a lightning tour of the range of new features in the language(s), and selecting one or two areas for a deeper examination.

This talk introduces and evaluates the suitability of Apache Ivy as a dependency manager for document and data transformation projects, which is less common in these projects. The proposed solution will provide an optimized set of templates based on the development of Arousa and test common scenarios like dealing with local repositories and setting up a shared network repository. The approach has shown that it is suitable for dependency management on XSLT and XProc transformation projects, and the code samples will be shared for future reference. The initial experience with Arousa seems to back the validity of the solution, and the templates provided can help with the added complexity.

This paper discusses the development of tools to explore and maintain XSLT, XQuery, and other markup-processing code. The tools described include freqx, Xarcissus, and Eddie 2, which help to explore sample documents and large DTDs. The paper also covers XSLT DTD-coverage testing and encourages others to take a similar approach in developing tools to explore markup.

In this talk, despite its misleading title, you'll discover how XML has been utilized in various publishing projects at The Academy of Performing Arts in Prague over the past 20 years.
