XML Hypergraph
See
http://taporware.mcmaster.ca/~taporware/xmlTools/hypergraph.shtml
Description
Tool uses Hypergraph Package (
http://hypergraph.sourceforge.net/) to display the structure of the submitted xml file. This tool requires jsdk1.4.2 or later. Otherwise, only the default hypergraph is displayed. (Note: If one node has more than 10 children nodes, only the first 10 children nodes are shown).
HyperGraph is an open source project which provides Java code to work with hyperbolic geometry and especially with hyperbolic trees.
Pseudocode
- Obtain XML string by URL or from user's local disk. If the text is not an XML, return an error message
- Use xslt file (based on the hypergraph rules) to translate the input xml string to a hypergraph enabled xml file so that it can be displayed in hypergraph format
- Generate an applet so that the hypergraph can be displayed in a browser
