Here is the working outline for the course:
Data Model Design Issues
Node design issues
What is the appropriate data model for a node?
What types of objects may nodes contain?
(Text, Graphics, Images, Audio,...)
What properties may these objects have? (color, etc)
What size should a node be?
What types of nodes should there be?
What sort of data object should be used as the source for a link?
What sort of data object should be used as the destination for a link?
How can nodes be aggregated into larger structures?
How can nodes be composed from other objects?
From other nodes
From other databases/files
How kept current?
How can versioning be supported? (Time versions, object variants)
Link design issues
What types of links should there be?
cold, warm, hot
Should a link have internal structure?
Should links have multiple destinations?
User Interface Design Issues
Target users (novice, casual, expert)
System Performance Issues
How does System response affect user performance?
What style of user interface should be used?
Direct maniplation, ...
Degree of directness
How should nodes be presented on the display?
Space multi-plexing or time multiplexing
Number of windows
Types of windows
Overlapping or non-overlapping
How should a link source/destination be presented on the display?
(Icons, highlighting, blinking, face types, underlining, ...)
How fast should the system respond when following a link?
Time to access and display new node in same document
Time to access and display new node in new document
Time to access, load, and initiate execution of programs
How should the system support browsing?
Should graphical views of the database structure be provided?
What types? How should they be constructed? Maintained?
How can disorientation be reduced? (other than overviews)
How can the user search other than by browsing?
What types of queries can be specified?
Exact match, best match, first match, ranked matches
How are the queries specified? (forms, example items, ...)
What types of searches can be performed?
What scopes for searching are available?
(Current document, Current hierarchy, Whole database, ...)
How is scope specified?
How is search performed (interactive, background batch, ...)
How are the search results provided (temporary|persistent; highlighting)
How can the user interface be tailored?
What features can be tailored? (e.g., defaults for newly created items)
How does the user specify the changes?
When do they take affect (immediately, next session, ...)
Multiple levels of functionality (how controlled?)
Application Design/Support Issues
How should the system support authoring?
What tools can be used to make authors more productive
How does the user change properties of objects?
How are properties of objects examined?
Domain specific versus Domain General
Support for specific domains
Electronic publishing (e.g., creating documents from hypertext)
Office information systems
Front-end to other systems (e.g.,databases)
Personal information manager
Support for collaboration
How can information be jointly authored and shared by multiple users?
How can interference among multiple users be reduced?
How is interference handled when it occurs?
How can access to sensitive data be restricted?
How can communication be supported?
How can annotation be supported?
How does the system support individual work?
How does the system provide for mutual intelligibility?
Script Language Design Issues
Target users (Novice, Casual, Expert)
Syntax of script language
Interpretation vs. Pre-Compiled vs. Runtime-Compiled
Ease of creation and maintenance
How are scripts represented?
How are scripts edited?
Loading and Execution
On-line help and reference manuals
On-line libraries of code
Platform classes (pc versus workstation)
Graphical user interfaces
Distributed database (locking, ...)
Backup and Archiving
Splitting and merging multiple databases
Display device dependencies
Internal versus external link storage
Storage representation formats (binary, ASCII)
Integration with other programs
Integration with other databases
Integration with other hypertext systems
Importing text files
Importing graphics files
Exporting to other formats
Control of external devices (Videodisk)
Use of standards
XII, Motif, Open Look, HyTime
