The AGROVOC Concept Server (AGROVOC/CS) Workbench is a web-based working environment consisting of numerous functionalities for the distributed management and enhancement of the AGROVOC/CS built from the AGROVOC thesaurus. Following the Semantic Web’s vision, that emphasizes collaboration in the development of data and metadata to be shared and reused across the web, the management of AGROVOC will progressively be transferred from a few individuals in FAO to a wider community of international AGROVOC experts. These interested and competent users will share the collaborative maintenance and extension of AGROVOC, one of the most frequently used terminological resources for agricultural information management in the world. Maintenance of the future extended AGROVOC will thus be completely decentralized with people worldwide contributing to its development. This report provides a brief note on the technical aspects of the AGROVOC/CS Workbench. Technical details †¢ Multilingual web interface and content (UTF8). †¢ The software is developed in pure JAVA (version 1. 5. x), with no calls to any third party modules requiring precompiled DLLs or other operating system specific features. †¢ The Google Web Toolkit (GWT) is used with an Eclipse plug-in for development of the system. It is used to build the system as a fully Java based AJAX client browser application that is compatible with all common web browsers. †¢ Where possible the JSP 2. 0 Expression Language (EL) is used for any JSP development within the project (it’s a way of writing script-less JSP pages). Protege OWL api framework is used to connect OWL. †¢ MySQL is used as RDBMS. †¢ The system is DBMS-independent. Additional database abstraction layer for interacting with the OWL backbone and the relational database will be used (e. g. the hibernat e persistence and query service, etc. ). The system follows FAO guidelines for HTML publishing: †¢ Guidelines for Web site development; †¢ File naming convention and file organization guidelines; †¢ Check list for the clearance of Web sites. In summary, the system is based on the following components: Development components †¢ Eclipse 3. 2 †¢ JAVA-JDK version jdk1. 5. x †¢ Apache Tomcat (that supports JSP and JAVA Servlets) Google Web Toolkit (for AJAX framework), version 1. 4. 60 †¢ Google Web Toolkit Incubator, version 1. 4 †¢ Protege OWL API 3. 4 libraries †¢ Hibernate 3. 0 libraries †¢ Hibernate 4 GWT, version 0. 5 RC2 †¢ MySQL version 5 Server side †¢ Windows XP, Windows 2000, or Linux †¢ Apache Tomcat 5. 5. 9 or higher †¢ JAVA-JDK version jdk1. 5. x or higher †¢ MySQL version 5 or higher †¢ Protege OWL API 3. 4 libraries †¢ Hibernate 3. 0 libraries †¢ Hibernate 4 GWT, version 0. 5 RC2 †¢ WAR file with compiled JAVA files and necessary libraries Current Server Configuration †¢ OS : Debian GNU/Linux 2. 6. 22-2 †¢ CPU: AMD 64 bit †¢ Memory: 8GB †¢ MYSQL version: 5. 0. 45 TOMCAT Version: 6. 0. 14 †¢ Java-JDK: 1. 6. 0_04 Required Application 1.
