Figure 4: A) plug in technology illustrated by the example of the Eclipse platform; schematic representation of the connection between plug-ins. B) Example openMASP: open Modular Analytical Software Platform; a demonstration project to show the advantages of Eclipse RCP-technology for programming of every time extensible modular analytical software; the base builds the Eclipse core plug-ins and OSGI-plugins above the ‘java virtual machine’; the next layer are the data structure plug-ins and the top layer are the functional plug-ins and the user interface.
