      LTPDA provides a framework for doing object-oriented data analysis. LTPDA objects
      can represent typical data structures needed for data analysis, for example, time-series
      data or digital filters. These objects can then flow through a data analysis pipeline
      where at each stage they record the actions. The output objects of a data analysis pipeline
      therefore contain a full history of the processing steps that have been performed in reaching
      this point. This history can be view to allow others to understand how results were arrived at, but 
      it can also be used to recreate the result.
