Linked Enterprise Data Services

2015/06 - 2018/05

The innovative growth core project Linked Enterprise Data Services (LEDS) is aiming at developing, establishing and merchandising the next generation of semantic, interlinked data driven applications and services based on the Linked Data paradigm. In order to achieve this goal, LEDS develops a technology platform, which will include competences, methods and concrete technological building blocks. The project is directly in line with the development of Web 3.0 and with the 2020 strategy for eGovernment. 


Crossmediale Mehrwertdienste für die digitale Mediendistribution

2012/08 - 2014/12

The junior research group Chrooma+ is exploring how to enrich audiovisual media with semantic interlinked information. The project is a cooperation with the professorships Medieninformatik and Technische Informatik. We are focusing our research on Web services, digital signage and interactive television.



2012/01 - 2013/12

MockupDD project intends to combine the high degree of end-user involvement provided by agile methodologies, with the productivity provided by MDWE (Model-Driven Web Engineering). MockupDD uses interface mockups (popular in code-based agile processes) to gather interaction and functional requirements, and then reuses them throughout the whole development process as valuable model specifications. These specifications provide also the foundation required to generate running web applications (even partially) by following an iterative enrichment process. MockupDD intends to be a hybrid agile and model-driven methodology to analyze, design and implement web applications. It promotes intensive end-user participation by incorporating user interface mockups as a common language between them and the development team. At the same time, MockupDD relies in the productivity provided by MDWE methodologies to quickly derive web applications from high-level models.


Open Mashup Enterprise service platform for LinkEd data in The TElco domain

2010/10 - 2013/07

The convergence of Telecom, IT and content services drives new emerging service markets based on an open Internet of Services. Mashups have gained big success in the so-called Web 2.0. The success of the Web 2.0 services has encouraged Telcos to expose their services as Telco Mashups, in order to provide third parties with facilities to build their business. Moreover, the exposure of network infrastructure as services is facilitating the entry of new API-driven telco agents that bring traditional telco services (telephony, messaging, IP location, etc.) to the Web. Yet, the technologies underlying each of the different mashup types are heterogeneous, which makes integration challenging. Also, mashups do not offer a universal composition model either, since mashup development is not vendor independent. A mashup developed within a specific technology has to be re-coded in order to be deployed in another engine. In this landscape, OMELETTE aims at researching on the development, management, governance, execution and conception of converged services with a specific focus on the telco domain. OMELETTE will create a sound model of mashups that follows the REST architectural style (also supported by standard widget technology), as well as a standard specification of a mashup-containing platform that may guarantee portability and interoperability among different vendors and versions. These concepts will be based on a solid theoretical model of mashup foundations and the specific requirements gained from the telco domain. OMELETTE will aim at breaking the barriers between the web, telecommunication and hybrid services, taking into account the convergence of IT/telecom/content systems. OMELETTE will foster as well the reuse of existing components and mashups, thanks to its automated service discovery functionalities. Project OMELETTE aims at developing an open platform for building convergent mashups for the telco domain to be used within several industry-driven use cases.


Web-based Federation Technologies for Science

2007/04 - 2008/12

The research project Web-based Federation Technologies for Science (codename "Hanoi") is concerned with the practical application of federated Web technology in real-life scenarios. This covers e.g. single-sign on access across Web sites, inter-organizational use of Web services, or federation management with the help of architecture registries.


Distributed Deployment Strategies for Web Application Components

2003/09 - 2004/02
The project is concerned with methods and infrastructure systems to support the handling of Web portal components. A main focus lies on the secure execution of foreign (potentially harmful) code as well as the portal-spanning exchange of components with Web-service based technologies.


WebComposition Markup Language

1997/03 - 2000/03
The WebComposition Markup Language (WCML) project was started in 1997 and provided the first basis for the WebComposition research focus. WCML describes an XML vocabulary for the WebComposition approach that allows definition of (Web-) components, properties, and relationships between these components. The WCML provides a generic mechanism facilitating compositional reuse. Distributed Components (nested in Virtual Component Stores) can be used to design and implement a Web-Application. The components may e.g. model high-level design concepts, like design pattern or OOHDM classes.


WebComposition Repository

1999/03 - 2000/02
Web application development suffers increasingly from the coarse-grained implementation model of the Web, as established software design concepts are hardly applicable to it. The object-oriented WebComposition Markup Language (WCML) addresses these problems with a fine-grained component-based model and thus supports the application of software engineering practice to applications in the Web. In this project, we introduce the WebComposition Repository as a key tool for a systematic approach to code reuse. The repository is used for storing, managing, and retrieving large numbers of WCML components. Consequently, it facilitates reuse in component-based Web Engineering.
