A Summary of the RGS⊕: an RDF Graph Synchronization System for Collaborative Robotics

In the context of collaborative robotics, distributed situation awareness is essential for supporting collective intelligence in teams of robots and human agents, where it can be used for both individual and collective decision support. This is particularly important in applications pertaining to emergency rescue and crisis management. During operational missions, data and knowledge is gathered incrementally and in different ways by heterogeneous robots and humans. This paper aims to describe an RDF Graph Synchronization System called RGS ⊕. It is assumed that a dynamic set of agents provide or retrieve knowledge stored in their local RDF Graphs which are continuously synchronized between agents. The RGS ⊕ System was designed to handle unreliable communication and does not depend on a static centralized infrastructure.
