init{
  var rl := LabResearchCategory{ name := "Routine Lab" number := 1 }; rl.save(); 

  LabResearch{ name := "T.W.B.C." category := rl }.save();
  LabResearch{ name := "RBS" category := rl }.save();
}

  entity LabResearch{
    name :: String (searchable)
    category -> LabResearchCategory (inverse=LabResearchCategory.research)
  } 
  
  entity LabResearchCategory{
    name :: String
    research -> Set<LabResearch>
    number :: Int
  }

workaround:

  rl.research.add(LabResearch{ name := "T.W.B.C." });
  rl.research.add(LabResearch{ name := "RBS" });
