Hi Chris,
I'm looking forward to seeing how the https://premis-event-service.readthedocs.io/en/latest/  PREMIS Event Service develops as this would allow for your (and my ) use case.

Subject: [PIG] Search/Index PREMIS-Data

Hi all,

I attended the PREMIS-Tutorial at the IPRES this week, but unfortunately
the really important questions only pop into my head, when I'm already
lying in bed, so I ask it here:

What is the best practice to be able to search quickly to a huge amount of
PREMIS-Metadata

For example:

I migrate files from one format into another with a certain tool and
document this process in the PREMIS-Metadata. Two years later I realize,
that the tool I used, was not behaving as expected. Therefore I want to
find all objects in my archive, that have been migrated with this
particular tool and I have to search through all the PREMIS-Metadata of all
of my archived objects. Do you store the relevant information only in xmls
and then you parse each of this xmls? Or do you store it in the xmls and
additionally index it in a database, which you can query? Or do you have an
other solution for this kind of problem?

Thanks for any help
Chris
