Hello,
Quoting and replying to your questions below.
>> 1) is it possible to recover the SWHID information using the 'slug'?
It's not possible.
>> I know that it is possible to get this information with
>>
>> swh deposit status --username ipol --password PASSWORD --deposit-id ID
yes, don't you keep the reference of the deposit id?
>> 2) is it possible to update some deposit (to add/correct some data
>> field) using the already existing deposit-id?
Yes, you can update deposit metadata information on swhid [1]
Use `swh deposit upload...`, passing along a metadata file with the
right information. I noticed the manual does not display that
information yet. I'll go and update that part.
There is also the possibility of updating a `partial` deposit (not
already ingested in the archive) using the deposit id.

Yes.

Heads up by the way, some of your deposits revealed an issue server side
[2]. It's fixed now. Some of the deposits were stuck because they
wrongly passed the checks. They got rescheduled and now some are
expectedly rejected with the specified reasons.
