The paper presents the BOLD (Buildings on Linked Data) framework to simulate dynamic Linked Data environments, next to an instantiation, a benchmark for Linked Data agents built using the framework. The BOLD benchmark provides a read-write Linked Data interface to a smart building with simulated time, occupancy movement and sensors and actuators around lighting. On the Linked Data representation of this environment, agents carry out specified tasks, such as controlling illumination. The BOLD framework runs the environment and provides means to check for the correct execution of tasks and to measure agent performance. We conduct measurements on rule-based Linked Data agents.
