Abstract [en]

Today information is managed within increasingly complicated Web applications which often rely on similar information models. Finding a reusable and sufficiently generic information model for managing resources and their metadata would greatly simplify development of Web applications. This article presents such an information model, namely the Resource and Metadata Management Model (ReM3). The information model builds upon Web architecture and standards, more specifically the Linked Data principles when managing resources together with their metadata. It allows to express relations between metadata and to keep track of provenance and access control. In addition to this information model, the architecture of the reference implementation is described along with a Web application that builds upon it. To show the taken approach in practice, several real-world examples are presented as showcases. The information model and its reference implementation have been evaluated from several perspectives, such as the suitability for resource annotation, a preliminary scalability analysis and the adoption in a number of projects. This evaluation in various complementary dimensions shows that ReM3 has been successfully applied in practice and can be considered a serious alternative when developing Web applications where resources are managed along with their metadata.

Abstract [en]

This thesis is driven by the motivation to explore a way of working collaboratively that closely reflects the World Wide Web (WWW), more specifically the potential of the Web architecture built on Semantic Web technologies and Linked Data. The goal is to describe a generic approach and architecture that satisfies the needs for loose collaboration and collective knowledge construction as exemplified by the applications described in this thesis. This thesis focuses on a contribution-centric architecture which allows for flexible applications that support loose forms of collaboration.

The first research question deals with how Web-based collective knowledge construction can be supported. The second research question explores the characteristics of collective knowledge construction with respect to the Open World Assumption (OWA). The OWA implies that complete knowledge about a subject cannot be assumed at any time, which is one of the most fundamental properties of the WWW. The third research question investigates how Semantic Web technologies be used in order to support such a contribution-centric architecture.

The thesis and its underlying publications are of a technical character and are always grounded in theoretical models and considerations that have led to functional implementations. The research has evolved in iterative development processes and was explicitly directed at building applications that can be used in collaborative settings and that are based on standardized Web technologies. One of the main outcomes, an information model, was developed together with such an application and provides a number of novel approaches in the context in which it was designed.

The validity of the presented research is supported by evaluations from different perspectives: a list of implemented applications and showcases, results from structured interviews that have investigated the suitability for various resource annotation processes, as well as scalability aspects.

The thesis concludes that it is ultimately up to the application how "loose" the collaboration should be and to which extent the OWA is incorporated. The presented architecture provides a toolkit to support the development of loosely collaborative applications. The showcased applications allow the construction of collaborative conceptual models and to collaboratively annotate educational resources. They show the potential of the used technology stack and the introduced contribution-centric architecture that sits on top if it.
