 ## Process documentation
 In DEEP, standardized computational analysis pipelines are documented in form of so-called *Process* specifications.
 A *Process* document lists required input and reference files, specifies the output generated by the pipeline and
 provides a step-by-step description of the computational analysis.
 *Processes* are in XML format and are rendered into a readable form when opened in a standard web browser
 (assuming an active internet connection). They are lightweight enough to be send via e-mail to collaboration partners.

 ## Analysis documentation
 Each run of a standardized pipeline produces an *Analysis* metadata document at the end. These are simple tab-separated
 text files listing all input, output and reference files as well as non-default parameters in form of *key-value*
