human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "db nets on the marriage of colored petri nets and relational databases"):
  Abstract: The integrated management of business processes and mas- ter data is being increasingly considered as a fundamental problem, by both the academia and the industry. In this position paper, we focus on the foundations of the problem, arguing that contemporary approaches struggle to find a suitable equilibrium between data- and process-related aspects. We then propose db-nets, a new formal model that balances such two pillars through the marriage of colored Petri nets and relational databases. We invite the research community to build on this model, discussing its potential in modeling, formal verification, and simulation.

Includes members:
  Member "homogeneous equations of algebraic petri nets":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "from db nets to coloured petri nets with priorities extended version")
  Member "verification of relational data centric dynamic systems with external services":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "specification driven predictive business process monitoring")
