Medical Dictionary Example

This example shows how eXist and XQuery can be used to view a Medical Dictionary. The main features of this implementation are:

• This is Document-centric XML, with markup interspersed in a textual definition of a term.
• Dictionary entries are supplemented with sound and image files
• Two XQuery scripts provide navigation to the definition of a term, and to all terms which refer to a term.

Scripts and Links

Sample navigation

• Larynx
• Cold
• Common Cold
• Search

Scripts

• definition.xql
• referrers.xql
• search.xql
• terms.xsl
• search.xsl

Text to speech

These script generate Voice+XML. Only Opera currently supports this XML vocabulary, and only two American voices can be used, one male one female.

• Larynx

Triples Model

A small fragment of a more basic model of the human body has been encoded as triples: subject verb object. At present the graphs are generated using PHP but it would be desireable to use only XQuery. Opera is a good SVG enabled Browser.

• Base data created in an eXcel spreadsheet.
• Generate Dot file for GraphViz
• SVG of connections generated from the data by selecting isConnectedTo facts. This goes via PHP until I can work out how to do this in Xquery.
• SVG of partOf relationships
• SVG Text of the PHP script.
• SVG generatedgenerates SVG but not yet from data
• SVG viewed in an IFrame
