The aim of the OTS conferences is to encourage close cooperation between people conducting research on component-related technologies and their users. Therefore, sessions usually incorporate papers presenting new technologies, those presenting a technology performance results and/or specific technologies in practice. OTS'2004 is devoted to changes in the IT industry related to Slovenia's full membership in the EU. We encourage authors to submit papers related to the goals, solutions and problems related to this change. Conference topics are:

• Model Driven Architectures (MDA),
• Information Portals
• UML with an emphasis on version 2.0,
• Techniques and methods for the software size estimation of object-oriented and component-based projects
• Patterns and their influence on development process and quality
• Improvements in software development methods (agile and conventional)
• Business interoperability with standards like ebXML, BPMI, RosettaNet and BPEL4WS, their comparison with previous standards (EDI, XLANG, WSFL) and practical experience with supporting standards (freebXML, Collaxa, BPWS4J, BizTalk, ChoreoServer).
• translation proposals for new English technical terms and their consistent use in practice

Take the challenge and present your knowledge, experiences and results with technologies related to conference topics. Your contribution will help organizers preserve the excellence of previous OTS conferences in Maribor (Slovenia).
