With hooks users can define actions that can trigger task execution of external TES services. Within the p2p network, specific nodes can be associated with specific compute resources, that can automatically trigger workflow executions. This powerful integration can efficiently route workflow jobs to the nearest compute resource to allow for data-to-compute patterns. Each job can be enriched with metadata information coming from the triggering resource action, helping to not only enrich metadata and data with provencance information, but also helping workflows to carry metadata information to external services.
