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 "koalja from data plumbing to smart workspaces in the extended cloud"):
  Abstract: Koalja describes a generalized data wiring or `pipeline' platform, built on top of Kubernetes, for plugin user code. Koalja makes the Kubernetes underlay transparent to users (for a `serverless' experience), and offers a breadboarding experience for development of data sharing circuitry, to commoditize its gradual promotion to a production system, with a minimum of infrastructure knowledge. Enterprise grade metadata are captured as data payloads flow through the circuitry, allowing full tracing of provenance and forensic reconstruction of transactional processes, down to the versions of software that led to each outcome. Koalja attends to optimizations for avoiding unwanted processing and transportation of data, that are rapidly becoming sustainability imperatives. Thus one can minimize energy expenditure and waste, and design with scaling in mind, especially with regard to edge computing, to accommodate an Internet of Things, Network Function Virtualization, and more.

Includes members:
  Member "a spacetime approach to generalized cognitive reasoning in multi scale learning":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "from observability to significance in distributed information systems")
  Member "spacetimes with semantics":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "locality statefulness and causality in distributed information systems concerning the scale dependence of system promises")
