Abstract. At the time of writing there exists no consensus about the approaches to detect, propagate and describe changes in resources and datasets of the Linked Open Data Web. This survey gives a comprehensive overview of the current technical solutions and a comparison of such based requirements we derived from use cases the community came up with. We give a detailed overview about the aspects of discovery, granularity level, and description of the changes, as well as the detection algorithms and notification mechanisms. Moreover, we present a high-level dataset dynamics stack that integrates the current technical solutions for dealing with changes in datasets of the Web of Data. 1 On the Importance of Dynamics of Linked Datasets So far, Linked Data principles and practices are being adopted by an increasing number of data providers, getting as result a global data space on the Web containing billions of RDF triples [8]. However, there are still various research challenges that must be overcome. One particular research challenge is datasets dynamics, and the
