| Abstract |
Conservation and restoration of works-of-art is a major duty for museums all over the world. These processes become increasingly IT-based in the last few years. Knowledge acquisition in this field employs examination and analysis methods based on digitization, image processing and data management and security techniques. However, there is a lack of information systems for managing, organizing and presenting information and knowledge relevant to the conservation of works-of-art. CREBITEL is an initial design and implementation of a Web-Based Information System (WBIS) with educational orientation concerning conservation. The system implementation follows a 4-tier architecture: 1st DBMS, 2nd application server, 3rd web server, 4th browser. The Semantic Index System (SIS) has been chosen as the DBMS, so modeling is based on the Telos semantic network data model. The model supports features of multilingual thesauri. It also relates the relevant terminology with specific paintings, for which there exist conservation reports and multispectral images. CREBITEL is accessed from the WWW through its Web application, which is executed on the Apache Tomcat application server. The Web application is fully parameterized and comprises a set of operations implemented with Java Servlet technology. The operations retrieve data from SIS through the available Java API, which uses native functions to communicate with the multithread version of the SISServer. The final results of the operations are exclusively formatted in XML according to predefined DTD. The presentation of XML results is independently accomplished using XSL files. The data-presentation independence is the basis for the features of multilinguality (direct language switch) and multipresentation, which differentiates this system from others. Last but not least, a design for data entry is proposed for the present system. It may be implemented with the use of "XML Entry Forms", so that loading can be relatively easy. The system was tested with virtual data and the performance of the several operations was judged as satisfactory
