[Archivesspace_Users_Group] Enumerations Findings

We have run into the case that some EAD attribute values are required to be NMTOKENs, thus no embedded spaces or other disallowed characters. We replaced enumerations with embedded spaces with underscores.

This has only come to my attention in the last week or so, so I haven’t made a thorough investigation of which attributes or which enumerations this applies to — just fixed them as I’ve encountered that error.

So it may be intentional that it is using the non translated value.
( And I wouldn’t be surprised, if for simplicity, it may be over applying that rule in places where it’s not actually required. )

At UNLV Special Collections, we've been working on cleaning up our enumeration values because in many cases there were duplicates caused by imports (i.e value: linear_feet vs value: Linear feet vs Linear Feet). We wanted to stick as close as possible to ArchivesSpace standards and decided to make our enumeration values all lowercase seperated by an underscore and then merge any records with incorrect enumerations into that correct value (i.e value: linear Feet into linear_feet). We also have some custom enumerations such as: value: oversized_box, translation: Oversized Box; digital_file; Digital File

After we had that set up correctly, we had some findings and was wondering if anyone has experienced the same things or had a standard we could use.

1. When generating PDFs and EADs the enumeration values that were custom (such as the oversized_box) would come out as machine readable oversized_box instead of using our local en.yml value (located in the local plugin).
     This was something I found in the EAD serializer (https://github.com/archivesspace/archivesspace/blob/master/backend/app/exporters/serializers/ead.rb#L490) and was able to create a temporary solution of generating it , but required altering the enumeration instead of referencing our file. I thought i'd point it out because anyone creating custom enumerations even with a translation in an en.yml  file would not see their change reflected in the EAD export. (I've attached an image reflecting this) Anyone experience this?

2. Another example of this case was in the container "type" attribute. Before something like Oversized Box would be export to EAD as is because that was it's value in the enumeration. After we changed the value correctly to oversized_box, it would export to the EAD container "type" as is and translate to the PDF as well. With some XSLT manipulation I was able to get it to show up as oversized box (shown in attachments). I've looked through https://www.loc.gov/ead/tglib/elements/container.html and cannot find an example of a two+ attribute value.

Should attributes be machine readable (i.e oversized_box), human readable (Oversized Box), or does it even matter? Of course, exporting it as Oversized Box would be easiest to translate a user friendly version to the user.

Excuse me for the lengthy post, I'm trying to be thorough with my explenation, but please let me know if you've come accross something similar or have a finite solution.
