6 Status: Company Approved Page 6/9 2 Alfresco architecture This section introduces the core components used in Alfresco Content Management System. It also presents a System overview and an initial architectural diagram in the context of the XML based publication solution for Eurostat. The information provided in this document is preliminary and based in the findings and conclusions of the current analysis. It is subject to evolution during the specification phase of an initial Prototype. 2.1 Core support frameworks Alfresco uses state of the art core components that assembled together provide a powerful, scalable and reliable Content Management foundation. They include: Spring - Spring is an application framework that includes AOP capabilities. Hibernate - Hibernate is an object-relational mapping technology Lucene - Lucene is an enterprise-scale full-text and metadata search engine MyFaces - MyFaces is an implementation of Java Server Faces 2.2 System overview The following diagram introduces Alfresco Content Management system s services. Figure 1 - Alfresco system overview

8 Status: Company Approved Page 8/9 3 XML based publishing solution in context This section introduces the proposed integration between Alfresco and the custom components to be developed for the XML based publishing solution for Eurostat. Technically speaking, both Alfresco and the custom components developed for the solution will be hosted on a JSP container (Apache Tomcat). The solution will also use: a file system to store documents and a relational database (like Oracle) in order to persist metadata and internal business related information 3.1 Custom components The following is a preliminary list (to be completed during the specification phase) of custom components that will be developed for the solution, and will extend Alfresco s own architecture: User interface components, built to integrate seamlessly with Statpub. Workflow custom components, to facilitate the integration with Statpub and support the collaborative business process (creation, authoring, proofreading, translation, publication). ODF custom generators, to facilitate the construction of ODF fragments containing tabular data and charts generated from external data sources. Digesters, to process and homogenise information coming from different data sources. Custom transformers, to produce publications compatible with the different output channels (PDF, mini Web sites, etc). Metadata extractors, to extract metadata contained in ODF documents, populating the Content Management System. Metadata assemblers, to stamp metadata on exported documents in order to facilitate tracking and control. Below we can see an initial diagram of the solution in context:
