Dynamics in linked data environments

Abstract

Linked Data resources represent things in the world, which change over time, i. e. the resources are dynamic. We want to address open questions in building complex applications that consume and interact with Linked Data resources. Applications that consume Linked Data need to know about the dynamics of Linked Data to efficiently obtain fresh data to build their logic on. To address this problem of freshness, we set up a study to observe the dynamics of Linked Data on the Web and provide insights into the dynamics of Linked Data on the Web. Increasingly, the Web not only provides read-only Linked Data resources, but also writeable Linked Data resources. We develop a model for dynamics in the context of writeable Linked Data such that complex applications can be built on this model. We last present an observer that tracks the execution of applications that interact with multiple Linked Data resources.
