PEDRo software components. The software components used in PEDRo. In essence, data flows clockwise from the top left, with three categories of user. The first category of user is the scientist who carries out data entry – this user must be intimately familiar with the experiment that has been conducted and the equipment that has been used. The result of the data capture process is a PEDRo XML file. This XML file is then checked by the database curator, who can then add the data into the database. Once in the database, the PEDRo Database Access software can be used to search the database and view its contents. The PEDRo software has been implemented over the Xindice XML database [12] using Java Server Pages [28].
