Hypertext in Engineering BIBA
  Kasper Østerbye
On a number of occasions it has been stated that hypertext is the perfect technology for supporting engineering teams in organizing information about ongoing and past projects. In general, hypertext has been proposed for interrelating such things as project diaries, schedules, documentation, blueprints, test requirements, standards materials, etc. In software engineering, program-related information is envisioned to be managed through a hypertext system that supports collaborative work. This workshop will bring together researchers working toward these visions, with workshop discussions concentrating on how these visions can be realized and supported.
   The workshop will be organized as a number of discussions around specific topics. Topics of interest include, but are not limited to:
  • Experiences of using hypertext in engineering
  • Requirements for using hypertext systems in engineering
  • Concurrent engineering, version and configuration control
  • Integration of documentation and specifications of design
  • Use of hypertext for software engineering
  • Hyperbase Systems BIBA
      John J. Leggett
    The hyperbase (hypermedia database) system architectures to be discussed are large-scale (tens of terabytes), open, distributed, heterogeneous and extensible with capabilities for computation and collaboration. Typical application environments are archival digital libraries, large-scale collaborative systems and large engineering enterprises. Discussion will concentrate on hyperbase systems and not hypermedia environments or user-interface issues except as they might impact the hyperbase.
       The areas listed below may serve as focal points for discussions. Participants are encouraged to identify additional areas of critical importance.
  • Models and Architectures
  • Node, Link and Structure Management
  • Browsing/Search and Query
  • Version Control
  • Concurrency Control, Transaction Management and Notification Control
  • Impacts of Application Environments
  • Courses

    Educational Uses of Hypermedia: From Design to the Classroom BIBA
      Daniel M. Russell; George P. Landow
    Objective: To provide a broad survey of educational uses of hypermedia along with specific advice for designing and deploying effective educational applications.
       Content: Hypermedia creates rich possibilities to dramatically expand on traditional educational practices. In this course we'll examine the state-of-the-art in educational hypermedia. At the same time, we'll be grounded in reality. Based on the instructors'real-world uses of hypermedia in a variety of educational settings, many stories will be told, examples will be given, and heuristics for selecting, using, and creating effective educational hypermedia will be illustrated. This is both a broad survey of the field and a course that can be directly applicable in your use of hypermedia for learning.
    The HyTime Interchange Standard BIBA
      Steven J. DeRose; David G. Durand
    Objective: This course will provide the essential background required to read the HyTime standard, understand its structure, and apply it in practical situations.
       Content: After a brief review of SGML, this course introduces and describes HyTime (ISO 10744) an SGML-based standard for representing hypermedia and multimedia documents. HyTime provides flexible ways of representing links, without constraining the kinds of data objects that can be connected by those links. HyTime also includes methods for handling both temporal and spatial rendering and synchronization. We will describe HyTime mechanics in some detail and will also include recommendations about its use.
    Introduction to Hypertext and Hypermedia BIBA
      Jakob Nielsen
    Objective: The goals of this course are to give attendees an introduction to the concepts of hypertext (non-sequential writing) and hypermedia (multimedia hypertext), to provide them with the background necessary to take more advanced courses at Hypertext'93, and to participate in the conference even if they are not hypertext specialists.
  • Definition of hypertext and hypermedia.
  • Survey of the state-of-the art of hypertext with several demonstrations.
  • Hypertext architectures and system-level hypertext.
  • User interface issues and problems in hypertext.
  • Empirical tests of the usability of hypermedia systems and documents.
  • Navigating large information spaces.
  • Putting Documents Online: A Manager's Guide BIBA
      Ann Rockley
    Objective: Participants will be able to evaluate information, identify key factors affecting decisions, and develop criteria for decision making in projects to put documents online.
       Content: There are a number of decisions to be made before beginning to put a document online. Making the correct decisions up front can save you months of work and assist you in avoiding pitfalls. This workshop will show participants how to identify criteria for document design and software selection based on the results of audience and information analysis. The pros and cons of different online document formats (e.g., document database, SGML, proprietary) and distribution methods (e.g. CD-ROM/WAN/diskette) will be examined. We will look at the issues of documentation management (link management, revision control, and multiple authors). Some of the pitfalls of conversion will also be reviewed. This course does not review issues of writing for online. A sample exercise scenario will be used throughout to assist participants in applying the information and skills.
    Becoming a CD-ROM Publisher BIBA
      Bruce Winters
    Objective: This course describes the current environment for CD-ROM publishing and outlines a general and cost-effective path to follow.
       Content: This course is a comprehensive introduction for the author, publisher, and user of electronic information delivered on CD-ROM. The course addresses both technology "nuts and bolts" issues and the management issues for successful CD-ROM publishing. Topics include user types, authoring tools, retrieval software, desktop production, effective use of hyper- and multimedia, platforms, CD drives, standards, distribution, security, allocation of resources, intellectual property rights, cost-benefit analysis, and project management.
    SGML for Writers: An Introduction to Document Structure and Analysis BIBA
      Elizabeth Gilmore
    Objective: The SGML concept that most affects writers is that SGML documents have a hierarchical or tree structure that is rigorously defined as a Document Type Definition or DTD. The primary objective of this course is for writers to gain sufficient knowledge of SGML to understand the role of DTDs in an SGML-based publication system. The course is designed to teach writers how to think effectively about SGML, not simply to understand SGML syntax.
       Content: After an overview of SGML-based electronic publishing, the instructor uses a sample document to introduce DTDs, SGML markup and the process of analyzing documents to identify and describe their structure. Following the instructor's example, participants analyze some short documents, describe their document's hierarchical structure in a simple graphic tree notation, and begin learning how to use SGML to describe document structures.
       The course is designed to give writers first hand experience with the decisions and trade-offs that are inherent in DTD development.
    Automatic Information Retrieval and Text Utilization BIBA
      Gerard Salton
    Objective: This course covers basic methodologies for dealing effectively with large full-text information files consisting of documents of different type and covering many different subject areas.
       Content: The course provides a brief introduction to basic text storage and file organization methods. Procedures are described for carrying-out a viable analysis of text content (text indexing) applicable to collections in arbitrary subject areas, for efficiently comparing query statements with stored items, and for optimizing the query formulations during the search process.
       Since long book-size documents are often processed, it is important to provide access to smaller text excerpts rather than only to full documents. Strategies are described for accessing text passages of arbitrary size, and for automatically linking related text passages. The manipulation of collections of linked text passages leads to procedures for constructing text summaries, identifying the main themes apparent in the texts, and implementing selective text reading and text traversal strategies. Such applications and other similar ones are briefly described.
    Designing Electronic Publications: How We Do It BIBA
      Paul Kahn; Krzysztof Lenk
    Objective: The purpose of this course is to teach the design of electronic publications by leading participants through the basic principles of visual rhetoric and logic, highlighting those universal elements of visual design that apply to design for the computer. We will focus on issues of information design, symbolic and representational language in icons, the challenges of type on the computer screen, and methods for representing hypertext links.
       Content: The lecture will be illustrated with slides of information design examples, computer animations of effective typography on the computer screen, and examples of electronic publications produced by the instructors. We will illustrate the methodology used to develop visual language for electronic publications such as online software and hardware documentation, college-level text books, and consumer reference books.
    Visual Language: Analyzing the Emerging New Language Combining Words, Images, and Shapes BIBA
      Robert Horn
    Objective: Visual language is an emerging new language composed of words, images and shapes, which are tightly coupled. So closely are words and visual elements integrated that, in many communication situations, we can not do without either. This course will focus on approaches to analysis of visual language as a language and such topics as how to integrate words and images. The outcomes for participants will be a greater understanding of visual language and a greater propensity to use it in their own communication.
       Content: This course will present evidence for why we should begin to treat visual language as a language that most of us will be "speaking" more frequently in the next 10 years. We will analyze visual language to sort out what words do best and what the images and other shapes contribute. We will then explore what is known about the "systematics" (the grammar and semantics) of the language. Finally, a wrap-up group discussion about the hypermedia implications.
    Interactive Learning Environments: Where They've Come from and Where They're Going BIBA
      Elliot Soloway
    Objective: To enable attendees to better understand the alternative computing technologies that are available for learning, teaching and training, i.e., strengths/weaknesses, technology & classroom requirements, domain/task applicability.
       Content: A historical survey of the various teaching and training technologies will be given. The architectures of computer-assisted instruction (CAI) systems, simulations, intelligent tutoring systems (ITS), microworlds, and interactive learning environments (ILE) will be described. Emphasis will be placed on how the 90's computing infrastructure (e.g., high-MIP/GIP computation, high-bandwidth networks, multimedia, portable computing) will impact teaching and learning.
    Hypermedia Documents for Regulatory and ISO 9000 Compliance BIBA
      Bruce A. Warren; Neil W. Blahut
    Objective: You will be able to decide if you need electronic document management and delivery to meet OSHA and ISO 9000 requirements. You will be able to identify, specify, and satisfy the architectural and user interface requirements that distinguish a document management/workflow system suitable for white collar document creators, and a plant floor hypermedia tool that will be accepted and used by production workers.
       Content: Electronic at-the-job information is almost the only way to meet OSHA and/or ISO 9000 compliance requirements without large staff increases to handle paperwork. Case histories from three large chemical companies that have implemented OSHA/ISO hypermedia projects will be used as examples and project planning templates. The case studies will illustrate how to identify the information needs of production workers. We will explain and demonstrate user interface designs for packaging and delivering information in ways that plant floor workers can absorb while on the job.
    Forging the Business of Hypertext Publishing BIBA
      Dale Dougherty
    Objective: This course provides a basic understanding of how publishing works as a business. It reviews current academic and commercial experimentation with distributed hypertext publishing to explain how technological innovations in distribution are changing the activities and economics of publishing.
       Content: Traditional publishing consists of acquiring or developing content, manufacturing the content as a tangible product, and marketing and distributing those products in volume. Large computer networks such as the Internet are making it possible for a new kind of information publishing that incorporates hypertext technology on a global scale. We will look at existing Internet-based models for distributed information servers. In particular, we will look at the WorldWideWeb, a hypertext project originating at CERN in Switzerland. We will examine how information servers provide a useful framework for satisfying the requirements of the owners of information as well as providing transparent access to users.
    Text to Hypertext Conversion: A Practical Engineering Approach BIBA
      Mark Chignell; Bernd Nordhausen
    Objective: This course is a comprehensive survey of how people are solving the problem of converting text to hypertext, and it focuses on practical engineering approaches. Participants will gain the required knowledge to convert existing text to hypertext.
       Content: This course begins with an overview of the conversion problem, and an introduction of the two basic problems, node segmentation and automatic linking. We then show how SGML can simplify the conversion process, and improve the quality of the resulting hypertext documents. In addition, we touch upon several advanced topics of hypertext conversion, such as lexical and linguistic approaches for automatic linking, and signature methods. The course also includes an evaluation of different conversion methods and a demonstration of conversion tools.
    Hypermedia in Museums BIBA
      David Bearman
    Objective: This course surveys the use of hypermedia in museum exhibitions and reviews the unique requirements for hypermedia applications in the museum context. Participants will be better able to understand issues of design, copyright, production, staffing, standards, and distribution that determine the success of museum applications.
       Content: The workshop will explore the museum setting as an environment, museum audiences, and the design consequences for interactive multimedia. It will demonstrate and discuss examples of the best hypermedia applications installed in or developed by museums worldwide.
       Requirements specific to the museum setting will be matched to capabilities and features of hypermedia. Production related issues, including contracting with museums, copyright concerns of museums, hardware and software requirements for delivery in museum environments will be discussed.

    Evaluating Hypermedia Usability BIBA
      Gary Perlman
    Objective: To introduce cost effective methods of evaluating hypermedia systems, particularly early in the development process, when redesign is least expensive. To provide participants with enough experience during the course so that they are able to apply the methods on their own.
       Content: The course introduces a development methodology for hypermedia applications designed to enable cost-effective evaluation and usability testing. The course will focus on three methods for evaluating systems: Observational Skills and Video; Program Instrumentation; and Questionnaires and Checklists. All three methods are designed to be used by a broad base of evaluators, minimizing skill and equipment requirements. Participants will be given hands-on experience gathering and interpreting each kind of evaluation information.
    Hypertext in Legal Education and Law Practice BIBA
      Ronald W. Staudt; William R. Andersen; David E. Kiefer
    Objective: To provide a survey of current hypertext applications in law schools and law firms, including basic legal education for law students, training for new associates in law firms, continuing legal education for experienced attorneys, legal research, and litigation support.
       Content: The course will provide an overview of law as an inherently hypertextual domain. The instructors will describe specific hypertext and multimedia applications that are being used in the teaching and practice of law around the world. The instructors will discuss design and implementation methods and review lessons they have learned from extensive use of hypertext in legal applications.
    Metaphor Design in Hypertext Systems: Managing Expectations and Surprise BIBA
      Aaron Marcus
    Objective: This course will help participants manage the fundamental terms, images, and concepts in complex systems and displays that they develop for hypertext systems to make it easier for users to understand complex structures and processes. Participants will learn terminology, theory, and practical techniques that will improve their use of metaphors in products and provide guidance for research.
       Content: This course will begin with a discussion of user interface components, classical semiotics and rhetoric, and the history of metaphors in computer systems. Then we'll look at what is happening in the industry as the metaphors of computer systems are changing. We'll close with a pen-and-paper design exercise to explore the basic nouns and verbs of a hypermedia system.
    Cooperative Hypermedia Systems BIBA
      Norbert A. Streitz
    Objective: This course will help participants to evaluate the innovative potential of hypertext/hypermedia for CSCW scenarios and the need to expand hypermedia systems into cooperative systems. Learning about the roles of hypermedia, i.e. to be content of and medium for cooperative work, participants will gain a better understanding of the opportunities of cooperative hypermedia.
       Content: The course will begin by introducing the basic concepts of hypertext/hypermedia and selected scenarios of CSCW applications (e.g., document preparation, decision making and argumentation). These scenarios are used to discuss requirements for supporting synchronous as well as asynchronous cooperative work using hypermedia features. Examples of multi-user hypermedia systems are presented. This includes design decisions, system features and experiences. In addition, the integration of additional CSCW support (e.g. audio/video conferencing, shared screens) will be discussed.
    SGML for Implementers BIBA
      Steven DeRose; Darrell Raymond
    Objective: This course will help participants apply ISO 8879 Standard Generalized Markup Language to hypermedia applications. SGML's document model can greatly enhance portability and effectiveness of electronic documents. This course will demonstrate how to use SGML effectively, and the fundamental database principles underlying it.
       Content: We will focus on using SGML well (not merely "validly"); how to workaround certain rough edges of SGML; and how to think analytically about document models, structural design, and electronic documents. Attendees will learn principles of structured documents, means by which SGML supports them, and when to consider alternative techniques.
    Intellectual Property Protection BIBA
      Pamela Samuelson
    Objective: This course introduces the intellectual property issues faced by software developers, including the specific issues that are raised by the unique character of hypertext, multimedia, and digital libraries. The course is not designed to provide specific legal advice, but people taking the course will be much better able to seek and understand legal advice about intellectual property concerns.
       Content: This course will begin with an overview of the intellectual property system and the basic principles of copyright law. The course will explain why the special character of digital media poses problems for traditional legal models of intellectual property. The course will review and critique key judicial decisions on copyright protection for software, graphics, and multimedia.
    Presenting Information Visually: Graphic Design Principles for Use-Oriented Designers BIBA
      Suzanne Watzman
    Objective: This "device-independent" course introduces graphic and information design principles to professionals with no formal visual design training. Understanding and appropriate application of visual design principles are the criteria for successful communication of ideas. Today's challenge is as much an issue of creating good technology as making it intuitively useful. This course will demonstrate and instruct in the value of quality visual design when integrated into the user interface design process.
       Content: This is a highly-illustrated overview of principles and concepts, including: terminology, process, perceptual concepts, typography, page/screen composition and organization, forms/diagrams, graphics, color, style guides. Case studies and examples demonstrate principles in context and a guidelines section will summarize principles. This course WILL NOT turn participants into graphic designers! IT WILL demonstrate how understanding and appropriate application of these principles can make products easier to use and understand and, ultimately more successful.
    Resource-Based Hypermedia for Education and Training BIBA
      Wendy Hall; Hugh Davis; Gerard Hutchings
    Objective: This course will examine the potential for resource-based learning in education and training and show how open hypermedia systems can be used to create instructional material from large sets of multimedia resources. Based on examples drawn from a number of case studies, participants will be shown how such material can be customised and tailored to meet a variety of educational and training needs.
       Content: The course will show how hypermedia systems can be used to guide students through core instructional material whilst having full access to large databases of multimedia resources. Such environments can be customised and tailored to meet individual needs, authoring effort is reduced, and instructional material can be integrated with existing working environments. The course will present the authoring, navigation and interface issues of such environments through a number of case studies, drawn from both industry and education.
    Interactive Electronic Technical Manuals and the Content Data Model BIBA
      Bryan K. Caporlette
    Objective: The course explains the information requirements and user interface capabilities needed for Interactive Electronic Technical Manuals (IETMs), especially those based on the U.S. Department of Defense's Content Data Model (CDM). It will enable participants to plan an evolution from page-oriented technical manuals to database-oriented ones in which "neutral" information can be reused for different presentation devices and user tasks.
       Content: The CDM is an SGML-based specification that is required for defense contractors and which is well-suited for interactive manuals in air transport, automotive, and other applications involving maintenance of complex systems. The CDM supports context-dependent filtering, branching based on user interaction, dynamic generation of information, and other complex presentation techniques that can be exploited in IETMs.
       The course begins with an introduction and rationale for this model-based approach to technical manuals. It explains how the CDM distinguishes application-specific information from a "generic layer" and emphasizes how generic templates for information development can be applied in IETMs in a variety of industries.

Presentations will include examples of published works and projections concerning the future of electronic publishing.
    Corporate Conversion Strategies and Methodologies BIBA
      Daryl Savell; Robert Glushko; John Johnson
    Many organizations recognize the benefits of converting to on-line publishing and SGML source files. However, the transition from paper-based methods and proprietary authoring tools can be risky and expensive. Speakers from Passage Systems and Communitec will describe their experiences helping organizations convert to on-line publishing while preserving their sizable investment in technology, process, and legacy documents. Presentations will include a review of the benefits of SGML and on-line publishing, typical costs and problems in making the transition, and step-by-step guides to help ensure success.
    Building Embedded Hypertext Applications BIBA
      Dennis Egan; Bruce Warren; Dan Cunningham; Surend Dayal
    Hypertext as a technology is finding its way into many different application areas. As an integral part of applications in industrial process control, computer aided design, legal research, and many other systems, hypertext has become an embedded information-access technology. Warren Forthought, Intelligent Controls, and SoftLaw Corporation will describe their experiences in building and fielding embedded hypertext applications in industrial, engineering, and legal settings.
    SGML Authoring and Viewing Tools BIBA
      Victor Riley; Faye Merrideth; Jolana Leinson; Bill Smith
    SGML is an international standard for text representation that enables a single document source to take on multiple forms for viewing and printing across different platforms. Speakers from Arbortext, Frame Technology, and Electronic Book Technologies will discuss their tools for creating and delivering SGML-based data, and will demonstrate how their tools support the process. Both complementary and competing approaches among the vendors may emerge as they discuss and demonstrate their individual tools.
    Converting Legacy Data to SGML BIBA
      Robert Glushko; John McFadden; Harry Summerfield; David Silverman
    Electronic publishing and neutral data formats are attractive visions, but many organizations have large volumes of data in several different proprietary formats. How can these legacy printed and word-processor documents be converted to a single form that enables both hypertext and paper delivery? Representatives of Exoterica, Zandar, and Data Conversion Laboratories compare and contrast their approaches to converting legacy data. Typical benefits, costs, and problems associated with data conversion will be discussed, along with presentations of vendor tools and services for aiding the process.
    Minimum Platform Hypertext Tools for Technical Publications BIBA
      Phill Murray; Scott Johnson; Ronald Turner
    Hypertext is viewed by some as an expensive technology, requiring pricey software tools and high-end graphical workstations, but tools are available for creating and deploying high quality, cost effective hypertexts on MS-DOS computers. Representatives from Ntergaid and Sophware Supplements will present electronic technical manuals created and deployed on low-end PCs, and will discuss the creation and conversion processes. The emphasis will be on delivering low cost, high quality, electronic technical documents. Demonstrations will address problems such as automatic link-creation, approaches to handling graphics, and deployment strategies.


    Above and Beyond Publishing: The Inexorable Logic of Metamedia Publishing BIBA
      Ted Nelson
  • Closed media, unusable together, unable to quote from or link to one another,
       are creating a Balkanized world of electronic media. Whereas what we need
       is on-line media with comparable connections -- for scholarship,
       controversy, anthologizing, understanding, the reworking of ideas, and
  • A Point-and-click universe. We want to be able to jump from document to
       document, like a squirrel from branch to branch, passing through one
       document on the way to another, purchasing just that moment's portion.
  • Networked interwoven documents. We need to be able to treat the network as a
       seamless whole, and the contents as a unified docuverse.
  • Royalty. Owners need to be paid. Copyright is not an imposition; it is the
       compromise under which things are made available. The new system must
       extend it inconspicuously and innocuously.
  • Open hypermedia publishing. Everyone must be free and equal to publish, to
       comment, to publish links, to quote. Quotation can work within the
       copyright system, by purchasing the quotation from the document of origin.
  • Compatibility. Enough of this hardware incompatibility hogwash! We need
       compatible data, to which the hardware is a window.
  • Connectedness. Any document must be able to connect to any other.
  • Stability. We need to know the material will be addressable in the same form
       and the same way, decades from now.
  • A Populist System. This cannot just be for the wireheads, early adopters,
       elite; it must be accessible to all.
  • Open-ended technology, capped by trademark: a variety of database methods can
       implement this publishing model, in a mix of assured upward compatibility.
  • Defined by contract. Participants agree to unusual terms of sale, etc. No
       rights are relinquished by participants except within this closed system.
  • Promise of stability. Publisher and vendor agree to keep material in the

  • Arbitrary links. Any type of connection, from an expansible list of link
  • Quotation. Transclusion, or virtual instance pointer, says "buy from there." TECHNICALITIES --
  • Harpoon table. Inbound links and transclusion pointers are stored also with
       the destination document; this storage is paid for by those who point.
  • Local caching of transclusions. Quoted material may be stored with a new
       document, still owned by original publisher, but storage paid for by new

    Hypertext and Group-Enabling: Lessons from the Desktop BIBA
      Irene Greif
    Desktop products for individual use have been richly developed in the past decade. A generation of "group-enabled" products is now emerging to meet users' needs to share documents, graphics and models from the desktop. Key technologies for this group-enabling include messaging, versioning and distributed data. We show how Hypertext can be another valuable group-enabling technology in such application as spreadsheets, worked processing and presentation graphics.
    Writing Toward the Future: What Avant-Garde Writing Has to Tell Hypertext Designers BIBA
      George P. Landow
    In an important sense all writing in hypertext is experimental since the medium is taking form as we read and write. Electronic linking, one of the defining features of this technology, can reconfigure notions of author, text, reader, writer, intellectual property, and other matters of immediate concern to those who design hypertext systems or author documents with them. Because hypertext fiction -- writing at and over the edge -- sets out to probe the limits of the medium itself, it acts as a laboratory to test our paradigms and our fundamental assumptions. A sample of experimental hypertexts shows the ways they illuminate issues ranging from reader disorientation and authorial property to the nature of hypertext genres and the rules of electronic writing.
    Reengineering the Field: Hypertext in the 21st Century BIBA
      Robert Akscyn
    What goals (if any) should the field of Hypertext have and how should those goals be pursued? This talk will assess the current 'state of the field' and present some proposals for future directions.
