Collaboration is one of the most important topics regarding the evolution of the World Wide Web and thus also for the Web of Data. In scenarios of distributed collaboration on datasets it is necessary to provide support for multiple different versions to exist simultaneously, while also providing support for merging diverged datasets. In this paper...

Distributed actors working on a common RDF dataset regularly encounter the issue to compare the status of one graph with another or generally to synchronize copies of a dataset. A versioning system helps to synchronize the copies of a dataset, combined with a difference calculation system it is also possible to compare versions in a log and to dete...

The World Wide Web is an infrastructure to publish and retrieve information through web resources. It evolved from a static Web 1.0 to a multimodal and interactive communication and information space which is used to collaboratively contribute and discuss web resources, which is better known as Web 2.0. The evolution into a Semantic Web (Web 3.0) p...

Electronic resources (e.g. e-journals, e-books or databases) are gaining more an more importance in libraries. With AMSL we demonstrate a flexible electronic resource management system which enables libraries to manage their electronic resources with a domain adapted software based on the OntoWiki application framework. Due to its generic design an...

Zusammenfassung Knowledge Graphs (KG) provide us with a structured, flexible, transparent, cross-system, and collaborative way of organizing our knowledge and data across various domains in society and industrial as well as scientific disciplines. KGs surpass any other form of representation in terms of effectiveness. However, Knowledge Graph Engin...

The Semantic Web is about collaboration and exchange of information. While the data on the Semantic Web is constantly evolving and meant to be collaboratively edited there is no practical transactional concept or method to control concurrent writes to a dataset and avoid conflicts. Thus, we follow the question, how can we ensure a controlled state...

The World Wide Web and the Semantic Web are designed as a network of distributed services and datasets. The distributed character of the Web brings manifold collaborative possibilities to interchange data. The commonly adopted collaborative solutions for RDF data are centralized (e. g. SPARQL endpoints and wiki systems). But to support distributed...
