CMS: input for different steps in the reuse mode

[katilp]

Now the different steps in the reuse mode only accept uploaded files (I did not yet find where I would upload files) or repositories (which I found 💪 ).

We may want to reflect what would be the use of this part, and how the code is commonly structured. Some reflections:

• it is not likely that all these steps (ntuple prod, main analysis, other measurements...) are either in separate repositories or in single files. They may be in different directories of a repository, and if the code is in a single file, it requires at least a configuration file together with it.
• the use of this part - if filled in - would be to provide an easy-to-find answer to questions of type "where is your analysis code", "how was the background estimation in this analysis done" or "how was a nnn uncertainty estimated" typically in the review process, or when otherwise looking for information.

To make this useful, the options of uploading a file (without any context) or a repository (in which the part specific to this step is difficult identify) may not be the best. Would a possibility of pointing to a location in a repository (subdirectory ), or even better in a preserved workflow, be an option? Do you have better ideas @laramaktub @clelange ?

Sorry, I have no concrete suggestions. I would wait with defining this once we have some examples with CMS results on the REANA side.
