ISSN 1795-9713 Copyright © 2014, by University of Jyväskylä Jyväskylä University Printing House, Jyväskylä 2014 ABSTRACT Jauhiainen, Eliisa Deployment of XML for office documents in organizations Jyväskylä: University of Jyväskylä, 201, 63 p. (+ four included articles) (-\YlVN\Ol/LFHQWLDWH7KHVHVLQ&RPSXWLQJ ISSN) ,6%1 (nid.), 978-951-39-5600-4 (PDF) Licentiate Thesis Majority of the content in organizations is stored as documents. Structured documents, like XML documents, allow the structure definitions, document instances, and layout specifications to be handled as separate entities. This is an important feature to realize from a document management point of view. A class of similar documents with the same structure constitutes a document type. The documents are built from components that are logical units of information within the context of the document type. Office documents are typically authored using word-processing software, they are relatively short in length, and intended for human consumption. The development of open office standards brought XML to organizations’ office en- vironments and changed the capabilities of using document content in ways that were previously impossible or difficult. The aim of this research is to ex- plore possible benefits of using custom XML schemas in office documents and factors influencing the design of such schemas. This study reports findings from two action research studies. Both cases involved designing custom XML schemas for office documents with the case organizations. The research resulted in the increased understanding of real-life requirements and challenges of XML schema design for office documents and provided insights of XML-based office document use after implementation. The research area changed significantly since the study was started. When the research began in 2005, the open XML standards for office documents were still under development, yet office suites available had already XML support enabling the use of custom XML schemas. The longevity of the study has pro- vided an opportunity to closely observe the use of an XML-based office docu- ment authoring system using custom XML schemas in a case organization through the years. The contributions of this study are the insights to schema design efforts. The two cases revealed issues motivating organizations to con- sider custom XML schemas for their office documents and how XML document management can be analyzed and described. The use of schema design meth- ods was observed to be beneficial in both cases.

It’s been a long road, but luckily filled with light and many opportunities to grow. I would also like to express my warmest thanks to the reviewers of this thesis, Jari Multisilta and Tero Päivärinta, for their contribution and insightful comments. This thesis marks an end of an interesting journey. Luckily I have shared it with the best travelling companions possible, a group of very near and dear ones in the Department of Information Systems and Computer Science. The la- dies known as the Tricksters (i.e. “huiputtajat”) - Maritta Pirhonen, Minna Sil- vennoinen, Irja Kankaanpää, and Marjo Silvennoinen - all of you made this road more fun to travel. Thanks for the laughs, shoulders to cry on, sympathetic ears, and many great discussions. Sharing thoughts, ideas and a wide spectrum of feelings with you on research and life in general has been both enlightening and empowering experience for me. I would also like to thank Reija Nur- meksela, my “partner in crime”. Writing research articles with you is always a pleasure. Your insightfulness never ceases to amaze me. Some people enjoy afternoon tea at five o'clock, but Seija Paananen and I enjoy our seven o’clock coffee in the morning. Seija is without a doubt the heart of the Department of Information Systems and Computer Science, and one of the most significant supporters for me throughout these years. Your positivity is truly inspiring! I would also like to express my gratitude to the hardworking people in the Faculty Office. If I have done anything to make your everyday work even a lit- tle bit easier, I’ll take that as one of the most important accomplishment of these past years. Don’t ever forget how important and valuable work you do for the faculty staff every day.

    1 of 3 Looking to the Future BY JOHN BALDWIN FreeBSD’s 13.0 release delivers new features to users and refines the workflow for new contri- butions. FreeBSD contributors have been busy fixing bugs and adding new features since 12.0’s release in December of 2018. In addition, FreeBSD developers have refined their vision to focus on FreeBSD’s future users. An abbreviated list of some of the changes in 13.0 is given below. A more detailed list can be found in the release notes. Shifting Tools Not all of the changes in the FreeBSD Project over the last two years have taken the form of patches. Some of the largest changes have been made in the tools used to contribute to FreeBSD. The first major change is that FreeBSD has switched from Subversion to Git for storing source code, documentation, and ports. Git is widely used in the software industry and is more familiar to new contribu- tors than Subversion. Git’s distributed nature also more easily facilitates contributions from individuals who are Not all of the changes in the not committers. FreeBSD had been providing Git mir- rors of the Subversion repositories for several years, and FreeBSD Project over the last many developers had used Git to manage in-progress patches. The Git mirrors have now become the offi- two years have taken the form cial repositories and changes are now pushed directly of patches. to Git instead of Subversion. FreeBSD 13.0 is the first release whose sources are only available via Git rather than Subversion.

  • Triroff, an Adaptation of the Device-Independent Troff for Formatting Tri-Directional Text
    ELECTRONIC PUBLISHING, VOL . 2(3), 119±142 (OCTOBER 1989) triroff, an adaptation of the device-independent troff for formatting tri-directional text ( K9J+ דניאל ברי) 69K ) AND DANIEL BERRY זאב בקר) ZEEV BECKER 9 T Computer Science Department Technion , Haifa 32000 N , Israel X SUMMARY This paper describes a system for formatting documents consisting of text written in languages printed in three different directions, left-to-right, right-to-left, and top-to-bottom. For example, this paper is such a document because it contains text written in English, Hebrew, Japanese, and Chinese. The system assumes that the input is in the order in which the text is read aloud, and it produces output in which each language is printed in its own correct direction, but for which a human cognizant of the reading conventions will reproduce the input order. The system consists of three major pieces of software: Ossana and Kernighan's ditroff for formatting text consisting of only left-to-right or unidirectional text, Buchman and Berry's ffortid for rearranging right-to-left language text occurring in ditroff output to be printed from right to left, and a new program bditroff for rearranging top-to- bottom text occurring in ditroff output to be printed from top to bottom. Below are translations of this English language abstract, except for this paragraph, into Hebrew, Japanese, and Chinese. The latter two are each printed twice, once in a modern left- to-right style, and once in a more traditional top-to-bottom style. The software described in this paper was used to format and typeset this paper.

  • Markup 101: Markup Basics Cynthia Zender, SAS Institute, Inc., Cary, NC
    Paper TU12 Markup 101: Markup Basics Cynthia Zender, SAS Institute, Inc., Cary, NC ABSTRACT Do you want to know what this "Markup" buzz is all about? Does it surprise you to know that the concept of "marking up" text for computers has been around since 1969? So what's all the excitement about? And what does SAS have to do with it? INTRODUCTION This paper provides an introduction to the concept of markup through concrete examples. The types of markup files which the author will discuss include: HTML, RTF, comma-delimited, tab-delimited, SYLK, WML, troff, LaTeX, Docbook, SGML and, yes, XML. We will compare the development of markup specifications with the development of WYSIWYG tools using a timeline of milestone development events. By the end of the presentation, you'll not only understand what the buzz is all about, you'll also understand how SAS can produce markup files and what kind of markup is possible. You will also receive a checklist of questions to ask at your company to help you figure out where to go next with markup and SAS. WHAT IS MARKUP? The concept of "markup" is as simple as a teacher with a red pencil "marking up" a student's paper or a copyeditor "marking up" page proofs with editing symbols. The key to making "markup" work is that the person marking up the content and the person processing the marked up content have both agreed on what the markup symbols mean. For example, "stet" written in the margin of a document means that something previously stricken out should be allowed to stay in the document.

  • Nroff/Troff User's Manual
    AT&T Bell Laboratories Murray Hill, New Jersey 07974 Computing Science Technical Report No. 54 Troff User's Manual² Joseph F. Ossanna Brian W. Kernighan Revised November, 1992 Troff User's Manual² Joseph F. Ossanna Brian W. Kernighan AT&T Bell Laboratories Murray Hill, New Jersey 07974 Revised November, 1992 Troff User's Manual² Joseph F. Ossanna Brian W. Kernighan AT&T Bell Laboratories Murray Hill, New Jersey 07974 Introduction Troff and nroff are text processors that format text for typesetter- and typewriter-like terminals, respectively. They accept lines of text interspersed with lines of format control information and format the text into a printable, paginated document having a user-designed style. Troff and nroff offer unusual free- dom in document styling: arbitrary style headers and footers; arbitrary style footnotes; multiple automatic sequence numbering for paragraphs, sections, etc; multiple column output; dynamic font and point-size control; arbitrary horizontal and vertical local motions at any point; and a family of automatic overstriking, bracket construction, and line-drawing functions. Troff produces its output in a device-independent form, although parameterized for a specific device; troff output must be processed by a driver for that device to produce printed output. Troff and nroff are highly compatible with each other and it is almost always possible to prepare input acceptable to both. Conditional input is provided that enables the user to embed input expressly des- tined for either program. Nroff can prepare output directly for a variety of terminal types and is capable of utilizing the full resolution of each terminal. A warning, however: nroff necessarily cannot support all fea- tures of troff.
