Combinatorial chemistry has emerged in recent decades as an approach to quickly and efficiently synthesize large numbers of potential small molecule drug candidates. In a typical synthesis, only a single target molecule is produced at the end of a synthetic scheme, with each step in a synthesis producing only a single product.
Chemical Markup Language (ChemML or CML) is an approach to managing molecular information using tools such as XML and Java. [1] It was the first domain specific implementation based strictly on XML, first based on a DTD [2] and later on an XML Schema, [3] the most robust and widely used system for precise information management in many areas.
