Record File's Original Name

Title (Goal)	Record Born-digital File's Original Name
Primary Actor	Repository Manager
Scope
Story	As a repository manager I want to record a file's original path as a PREMIS "originalName" property.

[seth-shaw-unlv]

Some of our repository materials are born-digital items where we want to record the original full path of the file. E.g. 2016-2018 photographs/neo000093-013.TIF. I propose we add a field to the various Media entities to record this.

[mjordan]

I agree with this proposal. However, we haven't discussed what approach to take to replace 7.x's Islandora PREMIS, but as part of the Islandora Riprap module, I started work (didn't get far) on providing PREMIS fixity event data at mjordan/islandora_riprap#5.

This is probably related to our meta issue on auditing (#927).

[seth-shaw-unlv]

We also need to pick which version of PREMIS we are using. Fedora 5 uses a PREMIS 1 namespace built-in (http://www.loc.gov/premis/rdf/v1#); the module @mjordan cites appears to serialize PREMIS 2 XML; but LOC appears to only recognize PREMIS 3 as an RDF ontology (the page for 2.2 says they have an OWL ontology, but the linked page only refers to v 3).

[mjordan]

PREMIS 3 is the one to go with.

[seth-shaw-unlv]

So, for this usecase we can use http://www.loc.gov/premis/rdf/v3/originalName which we can shorten to premis3:originalName.

Hey, sorry if I missed the discussion elsewhere, but why is the field storage in islandora instead of islandora defaults?

[seth-shaw-unlv]

I don't recall the original reason, but the pattern of placing the field storage configs for media fields in core feature and the field definitions in islandora_defaults was established by @dannylamb a while ago.

[seth-shaw-unlv]

You can see the existing field storage configs @ https://github.com/Islandora/islandora/tree/8.x-1.x/modules/islandora_core_feature/config/install. Now that I think about this, I seem to recall it has something to do with setting up views we can keep in core regardless of the field definition...

[dannylamb]

^^ That plus things like making a field multi-valued are locked down by the core feature and don't change unless we explicitly do so and then provide an update hook for.

Islandora/islandora#735 and Islandora/islandora_defaults#13 merged.
