The ARS is currently not considered to be a replacement for the ARM for Define-XML standard. However, components have been added to the ARS model to facilitate the creation of ARM for Define-XML, including the reason and purpose of each analysis and the ability to create documentation references for both analyses and outputs.
The creation and use of the ARS model is based on the assumption that the input analysis datasets will be "analysis-ready", as defined in Section 3.1, Fundamental Principles of the ADaM model document (add reference). This means that the ARS metadata components are designed only to define and describe the minimal additional processing needed to produce results from analysis-ready analysis datasets; they are not intended to describe more complex data manipulations such as transformations or transpositions.
