The amount of publicly available information resources on the Web is increasing rapidly. As this trend continues, finding these resources becomes more difficult. Several systems, notably Archie, Jumpstation, Lycos, WebCrawler, RBSE Index, and Harvest have attempted to solve this problem by building indices and allowing users to search them.
These Web-wide indexing solutions do not, in practice, share information with each other. In addition, the databases often fail to provide users with specific or complete answers to their queries.
This workshop has two goals: to find ways that index providers can share indexing and Web-structure information, and to explore ways to improve the query experience for users. Both goals stem from the need to address the increasing scale of the Internet: as the size of the problem increases, we need to be more efficient at building indices, and better at focusing on what the users are looking for. As we find solutions to these problems, it will enable us to build more efficient, consistent, and powerful indices of the World-Wide Web.
In addition to a general discussion of Web-wide indexing, the workshop will have two specific tasks:
Allowing indices to cooperate and exchange information can help solve several problems. First, it would allow the index builders to do a more efficient job of indexing. Indexing information for Europe might be collected in Europe, then transmitted in bulk to the United States. Or, we may find ways to build a distributed index, and avoid even the bulk transmission. Second, it would enable different retrieval engines to run against the same set of indexing information, providing better service for users and opportunities for research on different kinds of retrieval. Finally, it would server as an experimental tool for learning about decentralized indexing.
This workshop is not meant to set any standards for indexing or exchange of indexing information. However, if it serves as a starting point for the experimentation that will give us the experience necessary to propose standards in the future, should that be desirable.
The workshop environment is the ideal place to do this work; we will bring together people with experience building and running Web-wide indices. The ideal participant would be involved in building or operating an Internet information discovery system, or an expert in the field of database systems, distributed computing, expert systems, information retrieval, or library studies.
The workshop is open to everyone agreeing to contribute a short (less than 4 pages) paper or written participant statement. We want to have active participants in the workshops. The workshop chairs will decide on the program and presentations. Depending on the number of contributing participants the workshop may be opened also for additional non-contributing participants.

The World Wide Web (W3) is a fast growing information processing, browsing and retrieval tool, that runs on a wide variety of computer types. Up to now, it has been accessed primarily from office-, lab- or home-computers. But the simple yet powerful concepts of the W3 could also be used to build publicly accessible terminals (kiosks) that allow end-users online access to the W3.
This (half-day) workshop offers participants of the Third International World Wide Web Conference with W3-kiosk experience a possibility to meet and hold discussion on technical and organizational aspects of the introduction and maintenance of online kiosks based on the W3. The emphasis in the workshop is on the concept of "online." The goal is to discuss experiences with W3-kiosks that access remote data.
The workshop is open to everyone agreeing to contribute a short (less than 4 pages) paper or written participant statement. We want to have active participants in the workshops.

Using the Web as a tool for teaching and training means more than making course notes available, but how can we best use the Web to enhance these activities? There are questions of interaction, authoring, importing existing courseware and tools, and integration with other tools. A number of sites have gained important experience in this area; now is the time to share this experience and identify the principles, techniques and tools for teaching and training using the Web.
This workshop aims to pool experience in this area and to establish "best Web practice." We will also identify our requirements for future development of Web tools. Finally, we plan to identify or create a suitable forum for further discussions.
People who are using the Web for a major teaching or training exercise and who are interested in sharing their experience and discussing new ideas will be especially welcomed. Participants will be invited to prepare a short position paper in advance of the workshop.

Submission deadline: March 1
SGML is the general markup language on which HTML is based, and has been widely adopted since it became a formal standard in 1986. Many gigabytes of data have been encoded with SGML tag-sets other than HTML; many of those tag sets were specially designed for particular kinds of documents and other data. Using this data on the Web is impractical if it must all be translated into the single and small HTML tag-set. The SGML Open Consortium is working actively with the IETF and WWW communities to develop ways of delivering the vast collections of SGML data on the net effectively and easily.
This workshop will review the progress made so far, and work to achieve a wider consensus on how to manage fully general SGML data on the net. The most pressing issues right now include: MIME types for delivering SGML documents along with required information to handle them, such as their DTDs and style sheets; smart caching to allow re-using DTDs and stylesheets rather than re-fetching them for every document; DSSSL-Lite for interchanging stylesheets; helping with the finalization of HTML 3.0. We will devote time during the day to each of these topics.
This workshop is intended for anyone interested in how the Web can be used with large and/or diverse documents, whose structure may go beyond what HTML is intended to address, and also to anyone with non-HTML documents they wish to deliver. We view this as a real *work*shop, so attendees should be prepared to participate actively in the discussions and help resolve issues and questions.
The workshop is open to everyone agreeing to contribute a short (less than 4 pages) paper or written participant statement. We want to have active participants in the workshops. The workshop chairs will decide on the program and presentations. Depending on the number of contributing participants the workshop may be opened also for additional non-contributing participants.

This half-day tutorial gives an overview of the issues in designing and constructing multimedia user interfaces (MUI) for World-Wide Web applications. The special emphasis is on user interface principles and how WWW-documents can benefit from multimedia features. Based on an investigation of the as yet restricted features of HTML and successive document description languages, the aim is to discuss how to present a virtually seamless integration of multimedia within hypermedia WWW-documents. Within this context, the objectives are to analyze the users' and authors' requirements for hypermedia, and to present the state-of-the-art of multimedia user interfaces. Furthermore, the emerging principles and inherent problems of WWW browsers and editors are investigated, and solutions are offered in the form of revised user interface principles and design guidelines.
Themes include:
The tutorial is intended primarily for designers and authors of WWW-documents, either at the beginner or intermediate level. The participants will learn principles and techniques for designing better WWW-documents where multimedia is used as an integated aspect of the hypermedia network.

The explosive popularity of the World Wide Web has led to calls for greater privacy and security in this new environment, as well as intense efforts aimed at making the Web the basis for a "digital marketplace." Numerous projects are underway, adding new cryptographic capabilities to Web applications, defining extensions to the HyperText Transfer Protocol (HTTP), and attempting to integrate these features into the greater network security context. When combined with the frequent announcements of institutions promising to "bring security to cyberspace" or to "clear the way for commerce on the net", this makes for a pretty confusing scene.
This tutorial will provide an overview of current features and development activity pertaining to WWW security. After reviewing currently available methods for achieving access control, authentication and privacy on the Web, we will turn our attention towards recent proposals aimed at enhancing Web security and enabling new forms of commercial transactions. These new schemes will be covered at a level of detail dependent upon audience interest and familiarity, with demonstrations provided when applicable.
Anyone interested in these topics is welcome to attend. Familiarity with the basics of cryptography as well as fundamental system and network security will be helpful, though not essential.

The World Wide Web is an explosion of information and there are few guidelines or policies to help or hinder (as the case may be) the HTML author; it is a veritable electronic frontier. The regulatory vacuum in which we are now operating will become less so. How can we prepare ourselves for and manage this intervention, and how can we protect ourselves (employee and employer) from improprieties which may occur as a result of the lack of guidance provided to authors?
The tutorial "The Policy Wave is Coming: Authorship in a U.S. Government Agency Context" will provide the novice and the expert with salient information to guide the creation of their own HTML documents for publication on the WWW.
This tutorial will share direct experience in the creation of a network of Home Pages designed to represent the NASA High Performance Computing and Communications (HPCC) Program, and the coordination required in communicating and managing information spanning six (6) NASA research centers located across the United States. Additionally, the tutorial will demonstrate practical WWW applications for managing and scheduling projects between diverse organizations across large distances. The tutorial will also share the deliberations and controversy surrounding the topics of "regulation," "control," "security" and, "standards."
This tutorial will present results of interaction with the US White House Office of Science and Technology Policy's Information Infrastructure Task Force (IITF); specifically, we will present on the coordination of IITF Home Page usage in reporting NASA activities relating to the creation of a National Information Infrastructure (NII), and the Global Information Infrastructure (GII) initiative.
In sum, this tutorial will discuss the importance of responsibility, accountability, and quality control on the WWW and how these areas will affect the "wave" of policy making which will inevitably complicate our work out on the Web.
The tutorial "The Policy Wave is Coming: Authorship in a U.S. Government Agency Context" is intended for anyone who has contact with U.S. Government Agencies or anyone who may be impacted by U.S. Government policy decisions in this area. Policy and regulatory decisions impacting the WWW can have a major affect on those of us who live and work on the Web; this implicates a wide range of people as the WWW community is more than programmers and technologists. The WWW community is computer programmers, computer technologists, librarians, physicians, engineers, politicians, journalists, et al.; this tutorial is intended for just such diversity.

Interactive and distributed multimedia systems are key technologies rapidly evolving from marketing hype and research prototypes to commercial products.
Despite the great success WWW applications experience within the Internet community, the usefulness of the WWW in its present form seems to be limited to the presentation of static data. This restriction is not acceptable, especially for pretentious commercial applications.
The transmission characteristics of the Internet are not appropriate for high-bandwidth, low-latency audio- and video-based applications, with many users working on the same data.
Other information networks based on high communication rates, as appropriate for real-time requirements, like ATM or B-ISDN, are currently evolving. But still, only few applications exist that make use of these capabilities. Products as successful as the WWW do not -yet- exist in this field.
The aims of the workshop are:
Workshop participants should submit abstracts that directly address the aims of this workshop or fit into one of the following categories:
Representatives of industrial and research institutes are invited to discuss the above topics. The workshop will be jointly conducted by members of the System-Software Group (Kaiserslautern University, Germany) and the CEC Karlsruhe, a center for applied research of Digital Equipment Corporation.
The workshop is open to everyone agreeing to contribute a short (less than 4 pages) paper or written participant statement about work in the area indicated above. We especially encourage the submission of reports about practical experiences with multimedia systems and the Web. We want to have active participants in the workshops. The workshop chairs will decide on the program and presentations. Depending on the number of contributing participants the workshop may be opened also for additional non-contributing participants.

The goal of this workshop will be to gather interest from Webserver administrators from hospitals and medical research institutions around the world and to discuss ideas for establishing standards for sharing information among us. The ultimate purpose would be to put useful data on the Web for potential patients seeking physicians with particular specialties, as well as sharing discoveries in the medical research fields among hospitals.
Topics for Discussion:
Intended Workshop Participants:
Departmental Webservers are springing up in hospitals around the world. Anyone running a Webserver in a hospital or medical research institution should find this workshop an ideal forum for discussing the future of linking our servers and standardizing on homepages.I currently run the MGH Neurology Webserver with Dr. Anne B. Young (Chief of Neurology at Massachusetts General Hospital), and am in the process of "rallying" the other departments to put their information on the Web. By working with Harvard and MGH's Information Resources Department, I am organizing MGH's "Main" Webserver. I look forward to discussing the techniques I've learned and hope to hear from many other Webserver administrators. By forming contacts with each other and developing standards, we can make the wealth of information on hospitals and medical research institutions available to the general public in an easily navigated "webspace."
The benefits to patients and doctors worldwide would be fantastic.

We will give an in-depth tutorial on the NCSA httpd software, from the installation procedure to advanced configuration options.
We will explore its functionality and demonstrate how to create directory indices, how to restrict access to certain documents, how to write CGI scripts, how to handle forms, how to create sensitive images, how to perform WAIS searches, how to log information and keep statistics of server access, and how to fully take advantage of Server-Side Includes (SSI).
We will briefly compare its current status with other servers, in particular, the CERN httpd. We will also have a Q&A session regarding potential security issues when administering a Web site. Finally, we will outline future development directions regarding WWW server software at NCSA.
This tutorial is intended mainly for system administrators and people willing to fully explore the capabilities of the NCSA Web server software (httpd). We will go over the basics of installing and administering a web site, but a working knowledge and understanding of UNIX will be expected.

The Common Client Interface (CCI) allows external applications to access World Wide Web functionality by providing a mechanism with which it may communicate with a Mosaic browser. With this functionality user may enhance a browser application by writing a stand alone application that runs along side and adds additional features to the web session. This addition of functionality may be added to the environment without modifying the Mosaic executable. Further, a stand alone application may gain Mosaic functionality and access to the web by using the functionality built into Mosaic through the common client interface.
The CCI may be divided into two realms, local only and remote. The remote CCI is based on TCP/IP and has been implemented in the Unix version of Mosaic and will soon be in NCSA's PC and Mac versions. This session will concentrate on the remote realm where application and browser may exist on the same or remote machines.
This tutorial will instruct the attendee on CCI functionality, the programming interface (API) and the CCI protocol.
This tutorial is intended for developers who wish to either enhance Mosaic functionality by developing new applications that aid web browsing, or who wish to develop applications that have access to world wide web technology through Mosaic. It is assumed that the attendee will have some programming experience. The tutorial will cover the protocol and application programmer interface (API) used in the remote implementation of the CCI. Several API have been developed for the CCI including C, Perl, and Tcl. This tutorial will concentrate on the C interface.

The Client Communication Interface (CCI) is a mechanism built into the latest versions of NCSA Mosaic for Windows which allows other applications to communicate with Mosaic. The CCI consists of a collection of OLE function calls that can be made from other programs. For example, an application can use the CCI to ask Mosaic to access a World Wide Web document, download an Internet resource, or even send electronic mail.
This tutorial will introduce the functions that are available to the user, and demonstrate the use of those functions via examples and sample applications. Examples of CCI uses will range from simple Microsoft Excel macro function calls to stand-alone Visual Basic or C++ applications. Source code will be provided for all of the examples and sample applications.
The intended audience for this tutorial includes both Windows users and developers. As the simplest applications of the CCI, we will demonstrate how to use OLE-enabled applications -- such as Microsoft Excel, Microsoft Access, Quattro Pro, and others -- to access Internet resources. We will also briefly cover how to write standalone applications (using Visual Basic and/or Visual C++) for even greater flexibility. This will be covered in more depth in handouts rather than during the session.

or Now That I've Got An Identity, What Do I Do With It?
Currently, much of the activity surrounding security on the Web is directed towards authentication; making sure that the identity a program asserts is really its (or its user's) identity. As authentication schemes begin to be deployed, both developers and users will find that they need to consider authorization; what identities are allowed to take which actions, on what objects. This tutorial covers both authorization foundations and current authorization work on the World Wide Web, so that developers and administrators can make informed decisions about what sort of authorization mechanisms and models to use, based on their needs and the unique characteristics of the Web.
The following topics will be covered:
Authorization basics
We'll cover authorization's place in a security system and how it relates to and relies on authentication, the pieces needed (or used) for an authorization decision, and issues like dealing with multiple domains of trust and authority for user authentication, and authorization (including cascaded authentication and delegation).
Authorization models
These include basic authorization models such as Access Control Lists (ACLs) and capabilities, and authorization models in use in various contexts.
Authorization in Use
Examples will be provided of mechanisms for security, with an emphasis on those currently in use, and on distributed systems security. Candidate systems include: DCE and DSSA ACLs, capabilities in Amoeba, Kerberos proxies, roles in Oracle, Safe-TCL.
Authorization and the Web
Aspects of the Web that impact how authorization might occur, and the current state of authorization efforts on the Web will be reviewed. This information will be updated up to (and including) the actual tutorial.
This half day tutorial is targeted to Web developers, Web application developers, system administrators, and Web researchers with an interest in security, but with little background in authorization. No background in other security basics (such as authentication or encryption) will be assumed. Attendees will acquire an understanding of authorization's relation to other security aspects (particularly authentication) and a solid background in work-to-date related to authorization in security research, distributed systems, and the Web.
The Conference will take place at the Technical University of Darmstadt.

Panel Session on Wednesday, April 12, 1995
11.00 - 12.30
As the popularity of the World Wide Web increases, a growing number of industrial companies are interested in distributing their documents over the Internet.
Unfortunately, the structure offered by HTML is too simple to represent industrial documents such as part lists or maintenance manuals.
The only way that industrial users can make use of the Web for collaborative manipulation of their mission critical documents is to provide them with full SGML capabilities on the Web.
The aim of this panel is to discuss possible strategies to open up the web for real industrial applications.
State of the Art Report on Wednesday, April 12, 1995
14.00 - 15.30
Networked information discovery and retrieval is among the most pressing problems confronting users and information providers alike. The environment is characterized by competing object description models, confusion of terminology, legacy systems that do not interoperate, and a rich profusion of proposed solutions.
This panel will address the state of the art (and confusion) in this area, including the status of Internet Engineering Task Force Uniform Resource Identifier Working Group developments and the recent OCLC-NCSA Metadata Workshop.
The Developers Day will take place at the Maritim Konferenzhotel.
