<p class="MsoNormal">Colleagues,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Development Prioritization Team is seeking community input on a feature request for revisions to the Date subrecord in ArchivesSpace (ANW-380;
<a href="https://archivesspace.atlassian.net/browse/ANW-380">https://archivesspace.atlassian.net/browse/ANW-380</a>). The Date subrecord is used in multiple ArchivesSpace modules, including those for Accession, Resource, and Digital Object records. Changes
to the Date subrecord to support the EAC-CPF <dateRange> model were previously included in the Agents revision project specifications (ANW-429;
<a href="https://archivesspace.atlassian.net/browse/ANW-429">https://archivesspace.atlassian.net/browse/ANW-429</a>), and the new model would support either EAD2002/EAD3 <unitdate> or EAD3 <unitdatestructured> exports.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The primary change planned is the separation of begin and end date expressions in the application. For example, currently a single date expression is used with separate normalized begin and end date entries for date spans:
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><u>Date subrecord<o:p></o:p></u></p>
<p class="MsoNormal" style="margin-left:.5in">Date Expression: circa 1950-1960<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">…<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Begin: 1950<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">End: 1960<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Certainty: Approximate<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The revised model would include a separate date expression field entry for each part of the date span:
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><u>Date subrecord<o:p></o:p></u></p>
<p class="MsoNormal" style="margin-left:.5in">Begin Date Expression: circa 1950<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">…<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Begin Date Standardized: 1950<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">End Date Expression: 1960<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">…<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">End Date Standardized: 1960<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">…<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Certainty: Approximate<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The concern has been raised that institutions may not have sufficiently consistent data entry practices to allow a single migration script to parse existing Date Expression values into separate Begin and End date expression fields. One
proposed path has been to move the entire existing Date Expression value to the new Begin Date Expression, while moving the normalized dates to their appropriate standardized value fields. This would appear as:
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><u>Date subrecord<o:p></o:p></u></p>
<p class="MsoNormal" style="margin-left:.5in">Begin Date Expression: circa 1950-1960<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">…<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Begin Date Standardized: 1950<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">End Date Expression: <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">…<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">End Date Standardized: 1960<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">…<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Certainty: Approximate<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Development Prioritization Team would like to obtain feedback from the community regarding preferences for migrating existing Date subrecord content, or other concerns. Comments may be submitted through JIRA on the ticket for ANW-380
