"TopicMap" is a special Java applet designed to help you navigate topics on HighWire in a graphical form. The intent is to give you a sense of context while navigating a large, tree-structured database.

When TopicMap is launched, it appears in a separate window. As it may take 60 seconds or more to load, you will want to keep this separate window open to avoid having to reload frequently.

When results are selected (by double-clicking on a topic with more than zero documents), the results show up in the original browser window from which TopicMap was launched.

How to use TopicMap:

CLICKING on a topic moves it to the center of the display.

CLICKING AND DRAGING moves topics of interest toward the center and exposes new topics which had previously been minimized.

DOUBLE-CLICKING on a topic will show a list of the documents in the original web browser window.

TYPING a term in the 'Search for Topics" box will highlight all topics that have a topic name that contains the search term. The highlights appear as red triangles next to the topics. The 'enter' key will select the first highlight (the closest match to your search) and move it to the center of the window. Subsequent uses of the 'tab' key will take you to the other highlighted topics your search found.

If you HOVER over a topic (without clicking), you will see a popup window that gives the full topic name and the number of documents in the topic (if that count is greater than zero).

resets the search term and re-centers the display to the root node.

Can't Use TopicMap? [Macintosh] [Windows]

If you are using a Macintosh:

Internet Explorer below version 4.5: you will need to upgrade your browser to a more recent version and then follow the instructions below for '4.5 or higher'.

Internet Explorer 4.5 or higher: you will need to install Java support separately; this is available from Apple as the Macintosh Runtime for Java (MRJ).

You may also need to modify IE's application memory settings. Minimum and preferred memory sizes of at least 4096K seem to work if virtual memory is on. You will need to set it higher if you have virtual memory turned off.


TopicMap will not currently run on Macintosh Netscape, as Netscape's Java support is incomplete.

If you are running Windows:

Internet Explorer 3 or lower: you will need to upgrade your browser to a more recent version.

Internet Explorer 4 or higher:

Make sure that Java is enabled: Go to Tools > Internet Options. Under "Security Settings", select "Internet" and "Custom level...". Make sure that Microsoft VM > Java Permissions is set to "High Safety". For improved performance, enable "JIT compiler for virtual machine".

Make sure that JavaScript is enabled: Go to Tools > Internet Options. Under "Security Settings", select "Internet" and "Custom level...". Make sure that "Active scripting" and "Scripting of Java applets" are enabled.


Netscape 4 or lower: you will need to upgrade your browser to a more recent version.

Netscape 6:

Make sure that Java and JavaScript are enabled: Select Edit > Preferences. In the dialog box, select (+) Advanced and make sure that the check boxes for "Enable Java" and "Enable JavaScript" are selected.
