A schema mapping is essentially a data transformation function that can be executed on a dataset that conforms to one schema to another dataset that conforms to a different schema. In research, schema mappings have been used to refer to the logical formalism that specifies the relationship between two schemas. Schema mappings are typically use to combine data, from various sources, into a single unified format. While schema mappings can be manually specified by data scientists (it is a data transformation function afterall), they are typically automatically generated from schema matchings and further tuned by the user to suit particular needs.
We are not aware of any schema mapping tools that automatically generates Python code from schema matchings. It will be desirable to have a schema mapping tool with such a functionality.
