1. WS Organization

• Each participant is strongly encouraged to read all contributions before attending the workshop.
• The results of the workshop and the final contributions will be "published" as a WWW document tree. Participants are encouraged to share copyrights for that purpose (so that we can copy contributions to a stable server).

• Please see Phillip Hallam-Baker's workshop overview document (try this server workshop overview document if the previous results in an error) and related document on HTTP development

2. Declarations of Interest & Draft Contributions

A. Gateways to database systems

1. An architecture and implementation of a database system
   • Participant: David Eichmann, University of Houston - Clear Lake
   • Personal Home Page: http://rbse.jsc.nasa.gov/eichmann/
   • Site Home Page: http://rbse.jsc.nasa.gov/
   • email: eichmann@cl.uh.edu
   • Short Summary:
   • Draft Contribution: Integrating Structured Databases Into the Web: The MORE System
     Also see: The RBSE Spider - Balancing Effective Search Against Web Load
2. [A database interface implementation]
   • Participant: F. Pasian, R. Smareglia - Osservatorio Astronomico - Trieste, Italy
   • Personal Home Page:
   • Site Home Page: http://hpw002.oat.ts.astro.it
   • email: smaregli@oat.ts.astro.it
   • Short Summary: Lately, WWW has rapidly imposed itself as an extremely efficient way of accessing information spread on the Network. Therefore, astronomical applications dealing with data distribution have now a state-of-the-art and unified tool to be based upon.
   • Draft Contribution: SQL-ARCHIVE interface: WWW access to astronomical archives and databases
3. In absentia: [ WEB/Sybase Gateway using High-Level Specifications ]
   • Participant: Stanley Letovsky, Letovsky Associates, New Haven -- CT
   • Personal Home Page: http://cgsc.biology.yal e.edu/stan.html
   • Site Home Page: http://cgsc.biology.yale .edu/top.html
   • email: letovsky@cs.yale.edu
   • Short Summary:A declarative schema notation drives a SQL code generator that produces object-extractors, a table definition generator, and an html formatter, allowing dynamic Web access to objects in Sybase DBs. Retrofitting to existing DBs and creation of new ones are both supported.
   • Draft Contribution: http://cgsc.biology.yale.edu/ genera.html

B. On-the-fly page/image/image-map generation

Since this topic is highly related to database systems, in which all pages are generated on-the-fly, it will be discussed in the context of that section.

C. Extensions to the HTTP protocol

1. [graphical extensions using X]
   • Participant: Rainer Klute, Dortmund University
   • Personal Home Page: http://www.informatik.uni-dortmund.de/IRB/Klute.html
   • Site Home Page: http://www.informatik.uni-dortmund.de/
   • email: klute@heike.informatik.uni-dortmund.de
   • Short Summary: Although the World Wide Web brings the new dimension of multimedia integration to the Internet, displaying text or graphics, playing sound clips or videos is only part of the story. We also need a general mechanism to integrate (graphical) applications into the Web, ideally inside WWW clients like Mosaic.
   • Draft Contribution: General WWW Gateways
2. [Live video on the WWW using X]
   • Participant: H. Houh, D. Wetherall, D. Tennenhouse
   • Personal Home Page:
   • Site Home Page: /
   • email: hhh@mit.edu, djw@tns.lcs.mit.edu, dlt@lcs.mit.edu
   • Short Summary: We describe a Media Gateway which uses the WWW as an interface to a video database. Live video is deliversed using X.
   • Draft Contribution: The Media Gateway: Live Video on the World Wide Web
3. [Extending http to accomodate object-maps]
   • Participant: David Eichmann, University of Houston - Clear Lake
   • Personal Home Page: http://rbse.jsc.nasa.gov/eichmann/
   • Site Home Page: http://rbse.jsc.nasa.gov/
   • email: eichmann@cl.uh.edu
   • Short Summary: URLs could be associated with objects displayed in a frame, with the client determining the coordinate resolution to a URL, and then just jumping to that link.
   • Draft Contribution:
