Hello,
Quoting and replying to your questions below.
>> 1) is it possible to recover the SWHID information using the 'slug'?
No, it's not possible currently. Well, with the swh deposit status in
its current state.
We could imagine improving the `swh deposit status` to allow this. Note
that the result will most probably more than 1 deposit though.
>> 2) is it possible to update some deposit (to add/correct some data
>> field) using the already existing deposit-id?
Yes, we can update deposit metadata information now on the swhid though
[1]
Only updating a `partial` deposit (not already ingested in the archive)
is possible using the deposit id.

Yes.
