Process-centered and Data-centered approaches a In a process-centered approach (PCA) to the development of an analysis pipeline a well established process P ₁ is selected to build a new resource from input data. In the data-centered approach (DCA), the resource R ₁ has been created by prototypical code which needs to be properly structured and polished. b In the PCA the resource R ₁ has been produced and a well established procedure P ₂ has been selected to further process it. In the DCA the process P ₁ is now properly structured and the resource R ₂ has been created using prototypical code. c Both approaches finally yield equivalent pipelines and annotations
