Software tools for constructing hypertext systems
=================================================
Over the last six months, we've built several large commercial hypertext
systems. These systems are close to 1,000 files each, having perhaps 2,000
embedded links, and the same number of network nodes.
In database terms, these are relatively small systems. But with hypertext,
expert systems, or general programs, organizing information using 5,000 elements
into decision trees (or if statements) is a large system.
However, the entire literature of hypertext -- articles, books, and
existing products <FILE74> -- makes absolutely no mention of the type of
tools we use to rapidly build hypertext systems.
From our viewpoint, hypertext is more than a pretty screen. At the core, it's
categorizing and classifying information in order to serve the needs of users.
Tools for categorizing and classifying are central to hypertext.
Without such tools for creating, organizing, and managing link information,
the construction of hypertext frames (i.e., nodes, files, structures,
screens, pages) is haphazard. At best, the build-a-screen-then-link-it
approach leads to spaghetti hypertext, providing users with wandering,
where-am-I experience. <FILE28 HYPERTEXT> Lost-in-the-labyrinth
hypertext simply reflects poor management of the contained information.
<FILE62 VALUE>
However, the hypertext surprise is that only PC-Hypertext provides tools for
building structured hypertext. Why only us? Haven't others built large
systems?
From our own experience <FILE53 EXPERIENCE>, here are the various
processes and software we use to build effective hypertext systems <FILE30>:
┌───────────────────────────────────────────────────────────────────────────┐
│ Hypertext construction Software we use (and provide) │
│ ======================= =============================== │
│ Creating idea units SPLITTER <FILE32> │
│ Building indexes MARKER <FILE33> │
│ Inserting cross-links REFALL <FILE34> │
│ Checking link integrity IC (Integrity checker) <FILE64> │
│ Organizing decision trees DECISION TREE <FILE53> │
│ Classifying screens MaxThink and HOUDINI <FILE26> │
│ Translating structures M2H and H2H <FILE64> │
└───────────────────────────────────────────────────────────────────────────┘
We've assembled our hypertext construction tools into a package called
HYPERLINK, which is available from MaxThink for $89. From our experience,
you can build very effective hypertext systems in minimum time with these five
recommended software tools:
┌───────────────────────────────────────────────────────────────────────────┐
│ Type of software Recommended Price Reasons │
│ ================ =========== ===== ======= │
│ Run-time system PC-Hypertext None Cost, simplicity, speed │
│ Word processor Galaxy $49.00 Speed, windows, format │
│ Idea processor MaxThink $89.00 File management │
│ Network processor Houdini $89.00 Link management │
│ Hypertext utilities Hyperlink $89.00 Construction speed │
│ Dictionary/Thesaurus Ref-Set $89.00 Compatible & complete │
│ Grammar Checker Grammatik II $89.00 Thorough & helpful │
└───────────────────────────────────────────────────────────────────────────┘
All these software packages are available from MaxThink. Call for details on
how each package specifically aids the construction process of hypertext systems.
