Abstract: Darwin test enables the following functionality: Data Management. - To validate and check records from Darwincorev2 or Darwincore1.4 tables through queries that users can customize. - Activation and deactivation queries. - To create new validation queries to fit users needs. - To make direct corrections on wrong records through the validation forms. Those corrections can be set in a permanent way in the first Darwincorev2/Darwincore14 table or in a parallel table.

They have boundingbox for countries and provinces. Technical details - Error detection of omission, typographic, convention and consistency of the data. - DARWIN_TEST is based on Microsoft Access© XP. - Only a database Darwin_test.mdb and you can link the DARWINCOREV2 or DARWINCORE14 table and other referecence tables to check scientific names. - Graphical User Interface easy-to-use. - Open source code available on Sourceforge.net under the terms of the EUPL.
