Data-transformer: an example of data-centered tool set

This paper describes the data-transformer library, which provides various input and output routines for data based on a unified schema. Currently, the areas of the library's use include storage and retrieval of data via CLSQL; processing CSV and similar tabular files; interaction with user via web forms. Using the supplied schema, the data-transformer library can validate the input, process it and prepare it for output. A data schema may also include channel-specific details, e.g. one may specify a default HTML textarea size to use when generating the forms.
