Method and system for providing a net effect platform for developing and correcting screen scraping parser scripts

Individuals using a data management system are provided the capability to make corrections to default values presented in a simulation of at least part of a webpage including default data indicating the layout of the webpage, and/or one or more identified data fields determined by heuristic analysis and/or from data collected from other individuals/users. These contributing individual corrections are then transformed into contributing individual originated parser scripts associated with the webpage. The contributing individual originated parser scripts are then implemented and/or applied to the webpage for all individuals, including the contributing individual.
