SDX 2 Documentation Download Installation Presentation Architecture Server Document repositories Repository Multilingualism Configuration | # SDX-2 : Presentation The SDX project reaches version 2. It still aims at offering a « System for Documents in XML » under the GPL licence (open source). What is SDX useful for ? What is the contribution of the new version (for those who already know the first one) ? Document systems are very specific and have no large economic scope, why are they so expensive ? With the XML standard (and numerous related standards), document systems join general applications, many open source components are available. XML documents are getting common, various partners can share them, is it possible to connect a search and display interface without copying orginal versions ? SDX offers a search engine which can directly index URLs (repositories) ; it allows to define one or more indexing models (document repositories), with relevance ordering and its own layer to display documents (without modifying orginal versions). Our hosting provider offers a servlet engine, but with remote access only, including many restrictions. Is it necessary to call the Web administrator, each time something has to be modified ? An SDX server can be installed by performing few tasks : copy the archive in the servlets environment and restart the servlet engine once. To open an application, jsut do copy and paste. An expensive licence has been bought for using a powerful database, what an open source software can be useful for ? Is it professional ? Except several widespread products, commercial software industry does not gather as many skills, testers and situations as an open source project. The SDX architecture coordinates components which are well-known for being among the most generic, and which provide services that would not generate profit in a commercial context (including support, documentation, advertising...). SDX can provide full-text search functionalities to a relational system (including multilingual syntax analysis, including configuration and thesaurus) ; it can gather scattered information in a single document for display and preservation purpose. This flexibility relies on an architecture and four key concepts: the SDX server, applications, document systemsDocument repositories, and repositories. This part of the documentation aims at defining those concepts.
