Towards a global biological information infrastructure

چکیده
This paper analyzes the problems of working with large, mixed-origin taxonomic databases.The analyses were based in an example of a database that included more than 50 000specimens of Papilionidae and Pieridae butterflies of Mexico, obtained from ca. twentydifferent museums. The major problems and errors present in this database were classified aserrors of structure, consistency, and content. Errors of structure referred to faultynormalization or lack of referential integrity. Lack of consistency referred to contradictionsamong data fields, while errors of content included mistakes found from mere typos to factualerrors like misidentified specimens, faulty taxonomy or imprecise and equivocalgeoreferencing. Several ways of identifying and correcting errors are presented and discussed.
