Accessions, Resources, Archival Objects?

Hello Ron,

The divergence of the two date models within ArchivesSpace did come about with 
the work on the Agents module. While the plan is to eventually move other 
record types for which it makes sense to the same model (there are some related 
requests at https://archivesspace.atlassian.net/browse/ANW-1475 and 
https://archivesspace.atlassian.net/browse/ANW-380), because dates are so 
complex and because the agents work was underway already, we treated the work 
on dates associated with agents as a first step. The motivation for the change 
was specific to the EAC-CPF standard, though it has broader applicability with 
EAD as well.

I don’t have a specific timeframe for moving other dates in the application to 
this model right now. One of our thoughts in staging this date transition was 
that we wanted to get feedback on the agents dates piece before taking the even 
larger step of moving the other record types (and migrating the associated 
data) to that model. We haven’t received much feedback on the agents yet, 
possibly because a lot of people haven’t upgraded to a 3.x version yet or 
possibly because the new date model meets their needs just fine. We are 
currently reviewing prioritized projects against capacity in light of staffing 
changes and I intend to share more information and an updated roadmap soon.

I hope that helps. If you have other questions, or if anyone here has 
background or feedback specific to the agents date model, we’d be glad to have

Subject: [Archivesspace_Users_Group] different date models for Agents vs 
Accessions, Resources, Archival Objects?


I'm wondering why different date models exist for different record types in 

  *   Accessions + Resources/Archival Objects:

     *   Date Certainty: general certainty qualifier: "Approximate", 
"Inferred", "Questionable"

  *   Agents:

     *   Date Certainty: general certainty qualifier: "Approximate", 
"Inferred", "Questionable"
     *   Standardized Date Type: specific qualifier for both Begin and End 
date: "Standard", "Not Before", "Not After"

The extra field Standardized Date Type is occurring consistently for all date 
fields in the Agents module.

This raises some questions:

  *   What's the motivation for this difference? Is it standards-based, and 
does EAC-CPF allow for more detail than EAD? Or is is because the Agents module 
has been reworked more recently?
  *   In the latter case, is any harmonization foreseen for the date fields in 
Accessions and Resources/Archival Objects? If so, is there a time frame?

Many thanks for your thoughts!
