We have two ways: EITHER we just insert the URN in the description,
OR we want a machine to be able to parse it and hence we add an
additional field in the Capability_t.csv.
I think it would be reasonable to add a specific field for better
machine-readability.

true indeed. But we still have to agree on names.
I am thinking of something like (omitting some fields for readability):
Capability_t | Description |...| Reference documentation
=======================================================================================================================
data.transfer.http | capacity of moving a file from one network location |...| https://tools.ietf.org/html/rfc6585 |
| to another using the HTTP protocol |...| |
------------------------------------------------------------------------------------------------------------------------
data.transfer.https | capacity of moving a file from one network location |...| https://tools.ietf.org/html/rfc2660 |
| to another using the HTTPS protocol |...| |
-----------------------------------------------------------------------------------------------------------------------
data.transfer.webdav | ....
Also, agreeing on which RFC is crucial in my opinion.
Cheers,
Florido
