In this way self-describing documentation units are created. The creation of the XML files in principle is the responsibility of the archives. Within the project software and procedures were developed to assist them in the creation of output in XML format. In the future probably more and more information systems will facilitate the creation of data in XML format and it will become easier to manage data consistency between a local archive management system and the Web-based access system. Just like with the images the XML files are sent via FTP to the server of the EVA system.
Individual archives create XML files, extracted from the local archive information system.
The XML files are sent by the standard Internet protocol FTP to the server of the EVA system. End-users interested in access to a catalogue of images and descriptions, and users interested in the results of the EVA project and the model of the EVA system. Based on the information on the Web site an archive employee should be able to evaluate the relevance of the project results for the conversion and dissemination of its own collection. The XML formatted descriptions are automatically converted to the database on which the EVA system is based. Periodically the database is refreshed with new information that is sent to the server by the archives with the help of the FTP protocol.
