In addition to storing the VDJ rearrangements themselves, we need to store some metadata about the data set. This can include the version of the format we’re using, the software used to generate the data (incl. versions and cmd line options). What all should go into the metadata?
In addition, we need to propose a format for storing the metadata with the data. It can be done as a header to the data file, or can be done as a separate file. What are people’s preferences here?
