In the days of the overwhelming data and information burst of the 21st century, new and innovative handling approaches are necessary. With every single day, the importance of the statement of John Naisbitt increases, who once said that the human mankind is drowning in information, but starving for knowledge. Because of this, mechanisms are necessary to adequately present content. Therefore, this dissertation focusses on solutions that base on technologies of the Semantic Web and are targeting a proactive, holistic quality-driven content provision. For this goal it was necessary to define the process-oriented frame of this approach and to adequately model the subprocess of proactive content provision by taking into consideration the intended semantic and quality-related orientation. By this, it was possible to preserve the relationship of the specific solutions. To show the practical relevance, a primary focus was laid on the provision learning content within the domain of e-Learning. For the first preparation step, presented solutions are related to the analysis of relevant processes and process description approaches. This was the basis for the derivation of ontology-based descriptions of didactical expertise and e-Learning process models. Additional topic where the individualization based on user models for the lifelong learning as well as the proactive preparation of content for further processing. The second main phase was about the ontology-based provision of individualized content being enriched with additional information. The proactive presentation by graphical user interfaces was enhanced by agent technology concepts. Therefore, a common methodology as well as example scenarios have been developed. This work is completed by the presentation of manifold application examples of the developed solutions as well as conceptional proactive systems. The present dissertation is an important contribution within the area of tension of the proactive ontology-based respectively throughout quality-oriented provision of content. Especially for the domain of e-Learning methodologies, application scenarios, architectures and prototypical implementations were developed to implement and improve chosen aspects of the presented, innovative and quality-oriented QuaD 2-Framework. Steffen Mencke Otto-von-Guericke University of Magdeburg Contents Working on, writing and finishing a Ph.D. is an adventure that took me into the deepest universe of science with black holes slowing me down and wormholes pushing the speed of my learning. The beauty of the New and the wisdom of the Known form a unity, whose essence resulted in this dissertation and the experiences I made. It is not only boldly going where nobody has ever been before, it is also to know the roots where you are coming from. The most important roots, are the people one can belong to. At the very first place, this is the family. I owe the deepest thanks for their extreme support and patienceespecially from my wife Nicole. Without her I am nothing. Although many teachers, professors, reviewers and mentors guided the preparation of this journey, traveling between the stars of open questions, nebula of unsolved mysteries and borders of the mind is a way that can be hardly gone without a compass. So, I want to thank my adviser Prof. Dr.-Ing. habil. Reiner Dumke who was my compass, who called me in his group at the University of Magdeburg and gave me the opportunity and substantial support to make my Ph.D. I learned many things from him-not only professional expertise, but also many invaluable truths about the amenities and dangers of the world of research, science and academics. A next thank goes to Prof. Dr. Stanimir Stoyanov. His readiness to evaluate my work provided substantial parts of my space trip's finishing line. I hope for many revealing conversations in the future. Third, I want to thank Prof. Dr.-Ing. Cornelius Wille. His support and open mind were factors that I do not want to have missed. For him, I formulated the sentence: "Agents are not a new concept but their use in the field of ontology-based content provision constitutes a basis for consequential advances." A space tripe alone is a hard trip. So, it was very helpful to talk with many friends and colleagues-thank you all! Without the possibility to be complete, I especially want to mention: Dr. rer. nat. Fritz Zbrog: I liked our technical term creation sessions. Dmytro Rud: Did you found your sentence in my thesis? Stephan Vornholt: Brainstorming, eh?! Martin Kunz: Quality is the future!

While data is the raw material of information and needs a context for a meaning, information is an interpretable message already being related with a meaning and thereby being relevant for the receiver [Endres, 2004]. Knowledge is even more complex-it can be defined as the general awareness or possession of information, facts, ideas, truths, or principles gained through experience or association [American Heritage, 2003a]. Content can have multiple characteristics. In its glossaries, the World Wide Web Consortium (W3C) defines it as: Definition 2 Content is used to mean the document object as a whole or in parts [that is to be presented] to the user through natural language, images, sounds, movies, animations, etc. [W3C Glossary, 1999a]. Another definition from ContentWatch, an organization for the promotion of content management theory and practice, defines content as: Definition 3 Raw information becomes content when it is given a usable form intended for one or more purposes. Increasingly, the value of content is based upon the combination of its primary usable form, along with its application, accessibility, usage, usefulness, brand recognition, and uniqueness [Boiko, 2005].

Furthermore it is used to classify existing work and possible starting points for the future development of agent techniques and technologies order to enhance the performance and the effectiveness of several aspects of e-learning systems. Agents are not a new concept but their use in the field of e-learning constitutes a basis for consequential advances.

Defining e-learning as a single process, just with content development and content delivery/maintenance, only depicts a limited view to its complex nature. Many more detailed processes exist and can be described, analysed and optimised. This paper addresses this aspect. It is intended to provide background information about e-learning processes and their possible descriptions. They are used to start a discussion about useful and applicable e-learning process descriptions.

The invention provides a unique composite material capable of detecting and identifying multiple biological materials within a single package. The biological material identification system is designed for incorporation into existing types of flexible packaging material such as polyolefin films, and its introduction into the existing packaging infrastructure will require little or no change to present systems or procedures.

Unfortunately existing solutions are mainly focusing on functionality. But for the success of Systems Integration in the long run, the quality of developed architectures is of substantial interest. Existing quality-related information can be reused to optimize this assembly of components to thereby always provide the best possible combination. For this purpose a framework for the quality-driven creation of architectures is proposed in this paper. Besides this quality-oriented characteristic, the usage of semantic knowledge and structured process descriptions enable an automatic procedure. Especially the combination of both is a promising approach.
