Multiple generation(?) structure

[Sam Brenton]

Hi,

Is it possible to use pyPreservica to create an asset structure the mirrors this from 2 image files (tiff and dng)

I've epxerimented with the simple_asset_package and the complex_asset_package but the post-ingest structures aren't quite what I need 

Thanks in advance :)

Hi Sam,

 

I’m actually working on a project right now that uses that type of ingest structure myself; I’ve got some obsolete file formats that Preservica can’t migrate so I came up with a manual migration to do in advance and then upload both the original file and derived file as two separate Generations of the same Preservation Representation to Preservica, doing all this with OPEX/PAX:

 

https://developers.preservica.com/documentation/open-preservation-exchange-opex

https://developers.preservica.com/blog/using-opex-and-pax-for-ingesting-content

 

This results in something that looks like this:

 

You don’t even need pyPreservica for this step, as it’s just all about structuring the files inside nested folders to conform with the OPEX/PAX standard, which you can script using just the os and shutil modules. Hope this helps!

I dont think you can currently, pyPreservica supports multiple content objects within an Asset, but not multiple generations within a content object.

I will have to take a look at this use case at some point.
