human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "anonymized e mail interviews with r package maintainers active on cran and github"
  Abstract: This technical report accompanies a research article that empirically studies the problems related to inter-repository package dependencies in the R ecosystem of statistical computing, with a focus on R packages hosted on CRAN and GitHub. The current report provides supplementary material, reproducing an anonymised and sanitised version of e-mail interviews that have been conducted in November 2015 with five active R package maintainers. The goal was to gain a better understanding in how R package maintainers develop and distribute their packages through GitHub and CRAN. All five interviewees were actively maintaining packages on GitHub, some were also active on CRAN. They have been selected based on their profile (the number of R packages they maintain on GitHub and/or CRAN) as well as their gender (three interviewees were male, two were female).

Connected through hyperedge HE-1 (induced by source paper "an empirical comparison of dependency network evolution in seven software packaging ecosystems"):
  with members:
    - "on the interaction of relational database access technologies in open source java projects"
    - "a network perspective on software modularity"
    - "package upgrades in foss distributions details and challenges"
