XML

XML stands for eXtensible Markup Language. It's a markup language much like HTML. XML was designed to describe data. The tags in XML are not predefined as you need to define your own tags. It also uses a DTD (Document Type Definition) to describe the data. XML with a DTD is designed to be self describing.

Smiles

The simplified molecular input line entry specification or SMILES is a specification for unambiguously describing the structure of chemical molecules using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
