// Last, we expose our entity on an HTTP datapoint as Linked Data object. The ECA2LD lib will take care of building the correct

// This concludes the example. In the future, support to add datapoints on the Entity Collection should be implemented. This
// would automatize the process of creating datapoints for each entity manually.
