Finalize File Use modeling

[mcritchlow]

Descriptive summary

We need to reach agreement on our mapping of existing file use properties in DAMS4 to DAMS5. Longshou noted this is the last (major) mapping/modeling task that we've yet to finish.

If a meeting is needed let's get that setup.

Rationale

Because data models.

Going to initially assign @arwenhutt and @remerjohnson and then we can sort out ultimate responsibilities, next steps, etc., as needed.

@mcritchlow @lsitu
@remerjohnson and I discussed this today and he is taking lead on this.

There will probably be some questions here for ITS at some point, should he @ both of you?

[mcritchlow]

Yep that sounds good to me. We could hash those out here if that works, and then of course meet if needed as well.

[remerjohnson]

@mcritchlow @gamontoya So a missing piece of this for me is how functions similar to our notion of "File Use" work when just using the Horton/Hyrax interface. I'd like to make recommendations that are basically similar to current functionality, just in batch form. Or are all derivatives inferred from file type/format?

[mcritchlow]

@remerjohnson, @lsitu has the most experience in this. so pinging him to look at your question

[remerjohnson]

Thanks. Also would like to know if the PCDM Use is utilized by Hyrax or not.

[lsitu]

@remerjohnson As far as I know, the "File Use" work in hyrax is still on going and it won't be reflected in the Horton/Hyrax interface at this time. All files uploaded is marked as "original_file" and the derivatives are bounded to file type/format (which determines the derivative extension) for retrieving and no technical metadata is extracted and persisted in the Fedora/triplestore.
I think we can apply these file use properties you recommended to the Batch Import form so that we can have full support over the critical Excel batch import function as the first step, and then see what we can have from upstream to make it available on the horton/hyrax UI.
@mcritchlow Do you have any plans and thoughts on this?

[remerjohnson]

@lsitu So does that mean we can use what's in the existing Excel File Use vocab, or should I revise them?

[lsitu]

@remerjohnson We could but we had better map it to PCDM Use if we can, especially the related works are ongoing. If we can't stick with it, yes, we could implement our own set of file use properties. I have to mention that the file use in hyrax is not a property but a rdf:type with a url like http://pcdm.org/use#OriginalFile.
