The trend towards outsourcing increases the number of documents stored at external service providers. This storage model, however, raises privacy and security concerns because the service providers cannot be trusted with respect to maintaining the privacy of the documents. The research project SemCrypt^1 explores techniques for processing queries and updates over encrypted XML documents stored at untrusted servers. By performing encryption and decryption only on the client and not on the server, SemCrypt guarantees that neither the document structure nor the document content are disclosed on the server. Filtering query results and processing as much as possible of the query/update statement on the server does not depend on special encryption techniques. Instead, the chosen approach exploits the structural semantics of XML documents and uses standard, well-proven encryption techniques. SemCrypt thus enables to query and update encrypted XML documents on untrusted servers while ensuring data privacy.

In this paper we present our most recent work carried out in the wider context of the IST-ADRENALIN project, to facilitate formation and lifecycle management of networked enterprises. The projects focus is in designing and building an execution "kernel" for mobile agent applications written in Java, using the Aglets platform and integrating it with any existing ERP system. For integrating mobile agent infrastructures in operational ERP systems, we developed a generic model, which we call Mobile Agent Model, and which encompasses two parts concerning the Agent Logic and the Agent Proprietary data, analysed in more detail in this paper. This model is branch independent and builds on the Adrenalin Company concept, where the fractal and the Information supply chain concepts are combined, introducing that every process, activity and resource can be defined with the "triangle" of executor - controller - co-ordinator tasks, supporting characteristics of self-similarity, self-organisation, self-optimisation and dynamic organisational behaviour.

This article introduces the EC-project PROMOTE/sup /spl reg// (IST-1999-11658) where an overall framework for process-oriented knowledge management, starting at modelling knowledge intensive business processes in a Web-environment and focusing on the knowledge management processes such as identification, access, storage, distribution and evaluation where knowledge is being developed. The main focus of this text is the analysis of requirements of such a process oriented model based knowledge management system (KMS) and the system architecture of the PROMOTE/sup /spl reg// prototype. The application scenario "Quality Management for Software Development" is introduced to depict the realisation of the KMS.

The authors demonstrate that the concept of logical data independence as it is used in conventional databases can be applied beneficially to hypermedia modeling to achieve a clear separation between hypermedia data and applications. They show which aspects of logical data independence can be distinguished in hypermedia databases and describe an architecture which is constructed similar to the architecture of a conventional database. The paper is a continuation of previous work, in which they described how physical data independence can be achieved for hypermedia database management systems.

The book draws on invited papers selected from the proceedings of the 25th International Conference on Information Systems Development (ISD) held in Katowice, Poland, August 24 - 26, 2016. The invited conference papers were revised and expanded and present research that is focused on context, creativity, and cognition in information systems development. These issues are significant as they provide the basis for organizations to identify new markets, support innovative technology deployment, and enable mobile applications to detect, sense, interpret, and respond to the environment.
