Pedro is an application that creates data entry forms based o�n a data model written in a particular style of XML Schema. Users can enter data through the forms to create data files that conform to the schema. They can use controlled vocabularies to mark-up text fields and have the application perform basic validation o�n field data. When they feel they have finished writing a data file, Pedro can tell them if they have left out any required records.
