Table of Contents: The archive contains:
  1. folders representing a set of different data sets, that are softgauges representing profiles with very different characteristics together with the specification of the task, how to analyse the profile;
  2. three schema files to validate the json format of the data sets,
  3. a manual explaining how to the data sets.
To ensure that the results of the users are linked to identical tasks and profiles, a chain is created by referencing the MD5 checksum of the task file in the result and by referencing the MD5 checksum of the profile file in the task file. An MD5 checksum is a 128-bit hash value generated by the message-digest (MD) algorithm, a widely used hash function developed by Ronald Rivest in 1991. It is specified in the standard RFC 1321.

For each profile n=1,... at least one specifications file with a number k=1,2,... is given, that defines the analysis task with all necessary input parameters facilitating the participating institutions or laboratories to process their tasks.

For each test three zip archive files are assigned with following file names (the file extension name sg stands for softgauges):
  • prf_n.sg with the profile with the serial number n (provided in this archive),
  • prf_n_specifications_k.sg of the tasks (provided in this archive),
  • prf_n_lab_results_k.sg (to be generated by the user).
The three different types of files contain one json file each. For each type of json file exists a schema file accordingly, which are provided in this archive.

Further details are given in the manual manual_softgauges.pdf.
