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 "a core model for choreographic programming"):
  Abstract: Choreographic Programming is a paradigm for developing concurrent programs that are deadlock-free by construction, by programming communications declaratively and then synthesising process implementations automatically. Despite strong interest on choreographies, a foundational model that explains which computations can be performed with the hallmark constructs of choreographies is still missing.

Includes members:
  Member "applied choreographies":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "no more no less a formal model for serverless computing")
  Member "procedural choreographic programming":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "connectors meet choreographies")
  Member "dynamic choreographies theory and implementation":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "no more no less a formal model for serverless computing")
  Member "the paths to choreography extraction":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "implementing choreography extraction")
  Member "that s enough asynchrony with standard choreography primitives":
    also connected through other hyperedges:
      (none)
  Member "on asynchrony and choreographies":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "connectors meet choreographies")
  Member "choreographies divided and conquered":
    also connected through other hyperedges:
      - Hyperedge HE-6 (induced by source paper "the paths to choreography extraction")
  Member "choreographies in practice":
    also connected through other hyperedges:
      - Hyperedge HE-7 (induced by source paper "on asynchrony and choreographies")
