The THESEUS research program, funded by the Federal Ministry of Economic Affairs and Energy, aimed at the development of a new internet-based knowledge infrastructure in order to enhance and facilitate the effective use of knowledge available on the Internet.

For this purpose, a wide range of public and industrial research partners worked on basic technologies and technical standards. These technologies are vital for the subsequent development of innovative products, applications, services and business models for the World Wide Web as well as for the service and knowledge society of the future.

The Fraunhofer IAO conducted two projects within the THESEUS research program.

Concerning the topic of business models, work was carried out within the frame of the transversal working group »business requirements and models« that involved participants of all fields of the THESEUS project. The group’s findings were made available for the six THESEUS use cases. The major concrete tasks of the Fraunhofer IAO were the establishment of the THESEUS-wide working group and the preparation of subtopics, relevant across use case scenarios. Furthermore, the IAO carried out various workshops and provided solutions for »Next Generation Business Models«.

Within the use case TEXO, we developed an infrastructure for innovative, cross-company, web-based services. These services are moreover based on service oriented architectures (SOA) that facilitate a flexible and semantically oriented procurement between service provider and user. For this purpose, the Fraunhofer IAO described and evaluated use cases together with SAP and other partners and worked on concepts and tools to support the different stages of innovation in the process of service development. Furthermore, the Fraunhofer IAO developed methods and tools for a comprehensive modeling of services.

One focus of the THESEUS research program was on semantic technologies with the ability to recognize the meaning of information and categorize them accordingly. With the aid of the standards and basic technologies resulting from THESEUS, internet users should be able to create and edit contents, rules and regulations. In this way, the present Web 2.0 will be transformed through the combination with semantic methods into the internet of tomorrow.
