I. Developing and Maintaining a Decentralized Web

Katie Scheding, UCLA
Kelly Stack, idem
Kent Wada, idem

Web sites often spring up throughout an organization before an organization-wide Web plan is formulated. Neither radical decentralization nor radical centralization is effective: departments' needs must be balanced against the wider organization's needs. This tutorial discusses experience with such decentralized Webs at UCLA, and gives recommendations on managing them.

General understanding of the Web is required.

All three presenters have been heavily involved in UCLA's Web, are Webmasters of various sites at UCLA, and are members of the UCLA Campus Web Publishers' Group. Scheding has coordinates the UCLA Office of Academic Computing Web. Stack and Wada are members of the InfoUCLA team, which develops and maintains the UCLA CWIS.

Organizational and management issues are emphasized. It does not cover the use of HTML to create web pages, as does Tutorial A, nor the systems administration issues covered in Tutorial F. Tutorial B, A Highly Usable Site, emphasizes design and usability issues, and should be complementary to this one.

J. Web Image Databases: Formats, Sources, Organization

Andreas Bittorf, U. Erlangen

This presentation covers creating an image database on the Web, from the images themselves to the organization of the database. Examples will show the effects of compression, gamma correction, change of resolution, and color depth. Recommended design of the database and description system will be shown along with alternatives, and the effects of these design decisions on system and network load will be discussed.

Basic knowledge of databases and WWW technology is assumed.
