Abstract: Content-based retrieval of three-dimensional scalar data is increasingly necessary as on-line repositories of data volumes continue to grow. This paper describes preliminary work in retrieving and displaying scalar volumetric data via web-browser user interfaces. An HTML-based web-browser is used to construct queries based on user-specified textual keywords and a voxel value histogram. Shape-based query handling is in development. Pre-rendered images of volumes matching the user’s query are displayed and the user picks one of these to select a volume for further study. The selected volume is isosurfaced "on-the-fly", according to the user-supplied threshold value, and the resulting geometry is loaded into a VRML-based web-browser for interactive exploration and analysis. The system described here is being used as a platform for further research in content-based retrieval algorithms for volumetric data.

Abstract: A World Wide Web Common Gateway Interface package is described for accessing existing online interactive atlases of anatomy. The Web interface accesses the same 2-D and 3-D images of human neuroanatomy, knee anatomy and thoracic viscera that are currently accessed by a custom interactive atlas in distance learning courses. Although the Web interface is too slow to replace the existing atlas, it provides a parallel access path that has much broader potential for development of a distributed distance learning network in anatomy. By maintaining both access methods to the same information sources we continue to satisfy the fast interactivity needs for our local courses, while at the same time providing a migration path to the Web as the capabilities of Web browsers evolve.

Abstract: Substantial efforts to establish standards for encoding and accessing electronic resources have occurred over the past five years. We have designed a Web-based tool, called Spectrum, to enable individuals without specialized knowledge of library cataloging or markup to create records for describing and accessing networked electronic resources of various types. System users may create descriptions of electronic resources and view them as formatted USMARC bibliographic records, TEI headers and URCs. Because we anticipate continued volatility in the definition of data element standards, the Spectrum system is designed to allow maximum flexibility in the design of the input formats.

Abstract: This paper describes the current status of the World-Wide Web Library of Common Code 3 and the work done in order to start the convergence process towards a uniform Library. Currently many World-Wide Web applications are using different versions of the Library with a set of added functionality that is often either incompatible with the other versions or represents an overlap of code development. A new initiative has been taken at CERN 4 in the context of the W3C 5 collaboration with MIT 6 in order to converge the current versions of the Library so that existing and future World-Wide Web applications have a powerful and uniform interface to the Internet.

Abstract: This article is a follow-up to a comment I made on one of the CIDOC discussion lists. I suggested that many of the HTML \"pages\" out there on the World Wide Web would not pass close inspection by an SGML parser (i.e., a program that checks for valid SGML), even though in principle HTML is a perfectly valid application of the SGML standard. I went on to suggest that the value of these pages would be increased by making sure that they were actually SGML-conformant. This would allow them to be re-used for other purposes, by any SGML-aware software. \"Fair point,\" said our worthy Editor, \"tell us more\". So I tried. So what is SGML (and indeed HTML)?

Abstract: With the introduction of WEB browser and java related technologies, network management platforms, applications and agent development are being re-engineered to fit this new framework. Network equipment and software vendors are rushing to adopt WEB related technologies for competitive advantage.

Abstract: To reduce the number of resources needed for high quality music on the WWW, we advocate the use of client-side sound synthesis techniques. This paper discusses techniques extending the functionality of Web browsers and describes the design of the hymne class library, which is used by the hush Web widget to synthesize the sound of musical scripts embedded in HTML pages.

Abstract: New WWW services may be created either by extending Web protocols or by adding services in a lower layer. The DCE Web toolkit demonstrates that a broad array of new services can be provided in a layer below HTTP. Toolkit services include security, naming, and a transport-independent communications interface. Web applications can take advantage of these services by communicating their current protocols, such as HTTP, over the toolkit layer. The toolkit provides our prototype Web implementation with many new features, including security and location-independent hyperlinks without modification of the HTTP protocol and only minor changes to Web applications.
