XyMJava System for World Wide Web Communication of Organic Chemical Structures

Abstract

The XyMJava system for drawing chemical structural formulas has been developed by using the Java language in order to enhance World Wide Web communication of chemical information, where the XyM notation system proposed previously has been adopted as a language for inputting structural data. The object-oriented technique, especially the design-pattern approach, is applied to parse a XyM notation in the XyMJava system. A chemical model is introduced to encapsulate information on chemical structural formulas and used to draw the formula on a CRT display. Thereby, an HTML document containing a XyM notation can be browsed by the XyMApplet of the XyM Java system.
