GopherCON '95
______________________________________________________
This workshop/conference will be an excellent opportunity to
learn about next-generation information system technologies
such as GopherVR and the IICM's Hyper-G system in an informal
workshop setting.
Highlights of GopherCON '95 will include new technology such
as 3D user interfaces, applying spatial document clustering to
searching document collections, and hypermedia technologies
including the IICM's Hyper-G system (which supports Gopher, HTTP,
and Hyper-G clients and hypermedia authoring tools for hypertext
and video).
GopherCON '95 will be a workshop-format meeting with limited
attendance to promote discussion. Because attendance is limited,
we suggest that you register as soon as possible.

Session Descriptions

[1]--------------
GopherVR and VRML
-----------------
Next-generation user interfaces for Internet navigation will incorporate
3D scenes as both a graphical document type and as a way to visualize
relationships in a collection of documents (GopherVR). The new GopherVR
clients make it possible to view and navigate current Gopher servers'
document and link collections as 3D scenes, and Gopher+ servers can
easily give GopherVR clients hints about how to display the scene
representing a Gopher directory. GopherVR opens up a new visual
vocabulary for representing the relationships between items in Gopher,
while preserving Gopher traditional strength in serving low-end clients
with low bandwidth links.
This session is an overview of the design rationale and engineering
tradeoffs in the current GopherVR clients, how GopherVR hierarchies and
VRML documents address complimentary problems, and future directions for
GopherVR and VRML development.
[2]---------------------------
The Hyper-G Information system
------------------------------
Klaus Schmaranz <kschmar@iicm.tu-graz.ac.at>)
Currently, the most popular Internet information systems use
distributed menus and searching (Gopher) or hypertext documents (WWW) to
represent information spaces. The IICM at the Technical University in Graz,
Austria has developed Hyper-G, a second generation information system which
combines a structured hierarchy with hypermedia documents.Hyperlinks are
supported in all document types including text, images, movies, 3D scenes
and PostScript.
One of the most interesting features of Hyper-G is that links between
documents and directories are two-way links, so it is possible to traverse
the link in either direction. This makes it easy to view the collection of
all documents that point to a given directory or document (a good way of
finding related documents). Two-way links also make it possible to
automatically update hypertext references when a document moves; this is
a problem that is not handled well by either Gopher or WWW currently.
This session covers the Hyper-G system architecture, how Hyper-G clients
work, and an overview of authoring hypermedia in Hyper-G to be served to
Gopher, WWW, and Hyper-G clients, and will be presented by a member of the
Hyper-GJdevelopment group from Graz.
[3]-----------------------------------------------
Update on the IICM, NCSA, and Gopher collaboration
--------------------------------------------------
The Hyper-G, NCSA Mosaic, and Gopher developers recently announced a joint
development effort to produce VRweb 3D VRMLJclients for use with Gopher,
Hyper-G and Mosaic clients. This session is an update on the progress of
this effort.
[4]-----------------------------
Document Clustering for GopherVR
--------------------------------
One of the reasons for developing GopherVR is to make it possible to
represent relationships between documents in a collection by spatially
grouping the documents in a 3D scene. The is a particularly interesting
technique when applied to searching and browsing a document collection.
This session covers how we are clustering documents on GopherVR-aware
servers, and how other search engines can use GopherVR clients to display
clusters of documents.
[5]-------------------------------
Screen Scraping for Fun and Profit
----------------------------------
Screen scraping (harvesting information from 3270 terminal sessions) is one
way to to provide an easy-to-use Gopher interface to information that is
only available via a terminal-based interface. This session covers how a
Unix gopher gateway was written to efficiently harvest information student
grade information from 3270 terminal sessions, reformat the information,
and present it via Gopher. If you have legacy systems that are not going to
migrate to client/server technology anytime soon, you may want to apply
these techniques to free your data without creating a shadow database system.
[6]-----------------------------------
Gopher and OpenDoc component documents
--------------------------------------
The philosophy of the Gopher developers at the University of Minnesota has
always been to develop small, modular applications, and OpenDoc's component
architecture is a good match for this philosophy. This session will include
an overview of OpenDoc and how we plan to integrate Gopher with OpenDoc
documents.
[7]------------------------------------
Customizing Unix servers for 3D clients
---------------------------------------
This sessions covers how to customize an existing Unix server for GopherVR
clients. You'll find out how easy it is to take an existing Unix Gopher
server and have it return a +3D: attribute to specify a 3D scene.
[8]-----------------------------------
GopherSurfer, AppleSearch and GopherVR
--------------------------------------
An update on the popular Macintosh Gopher server software, how to integrate
this software with the AppleSearch full-text search engine and how to make
your GopherSurfer 3D-savvy.
[9]-------------------------------
Gopher gateway to Z39.50 and Isite
----------------------------------
Z39.50 servers are commonly used for library online catalogs, and there has
been a Gopher gateway to Z39.50 catalogs for the last year. This session
covers new developments in integrating Gopher with Z39.50 and Isite.
[10]----------------------
Integrating Gopher and WWW
--------------------------
HTMLJpages are a popular document format, while Gopher hierarchies are fast
to navigate and let you associate abstracts, alternate views, and other
meta information with any type of document. This session looks at how to
publish HTMLJdocuments from Gopher servers and point Gopher links at
HTMLJdocuments on WWW servers to serve the widest possible community and
take advantage of the strengths for both Gopher and WWW.
[11]----------------------------------------------------------
Using Gopher for Structured Searching of a Very Large Database
--------------------------------------------------------------
This session covers how to use FreeWais-SF and Gopher+ electronic forms
to publish and make searchable (by field) a very large database. Gopher+
forms make it possible to search on fields without exposing the user to
FreeWAIS-SF syntax. The database published was the Books in Print
database.
[12]-----------------------------------------------
Champagne Tastes on a Beer Budget
Linux as a Low Cost Option for a Gopher/HTTP Server
---------------------------------------------------
Steven Kirby <kirby@rhett.libs.uga.edu>
This session will discuss the University of Georgia Libraries' experience
running a Gopher and HTTP server under the Linux operating system. Our
server (gopher://scarlett.libs.uga.edu) has been in production for over a
year and has served over a quarter of a million transaction without a hitch,
despite the fact that the machine our Gopher server runs on is a lowly
386DX-40 mhz system with 8 megabytes of memory and a 420 Mbyte IDE hard
disk. This session will address a number of issues relating to running a
Gopher server under Linux, including hardware options, obtaining and
installing Linux, and selecting Gopher server software that is appropriate
to a particular site's needs. This session will be of interest to persons
and organizations who prefer the stability and functionality of a
Unix-based Gopher server, but whose budgets might not be able to
accommodate a workstation or server to run a commercial variant of
