Abstract

Embodiments of the invention provide a graphical rendering of source and target data instances enabling a user to select mappings between elements in the source data instance and elements in the target data instance. The data instances are typically input to embodiments of the invention as text files (e.g., DTD, XML, XML Schema Definition ('XSD') files, HTML files or the like), Additionally, in some embodiments additional characteristics or functions operating on data populating the mapped structures can be provided. Upon receipt of the mapping data (and, optionally, additional characteristic or function operations) embodiments of the invention generate a list of elements mapped from the target data instance. From this list, templates or code blocks are generated by embodiments of the invention which enable a script or source code file to be generated. The generated script or source code file, when processed on data streams of input data conforming to the original source data definition, will output a data stream which conforms to the original target data definition. The output data stream may be, for example, be formatted as an XML output file.
