Towards Linked Data Update Notifications

Linked Data resources change over time in terms of both content and relationships among them. Resources in a dataset might be frequently inserted, deleted, updated, and linked to other resources. Datasets are consumed in a lot of useful applications that would benefit from real-time notifcations when data changes in RDF data stores. sparqlPuSH describes a notification service for updates in RDF stores. Analyzing this approach and the implementation for applicability, it became obvious that a number of serious constituent problems have not been addressed and remain unsolved. In this paper, we review sparql- PuSH approach and we introduce our own vision and ideas in extending and generalizing it
