[Archivesspace_Users_Group] Extent questions

[Dallas Pillen]

Johanna and Mark,

The Bentley has also been doing a lot of work to break up our formerly
single extent statements containing multiple parts into partial extents. As
part of this work, we also noticed the limitations of the ArchivesSpace EAD
importer for importing partial extents. We made some changes to our EAD
importer plugin to properly handle altrender="part" attributes.
Additionally, we added some extra functionality to make sure that physdesc
contents don't get broken up into multiple notes. For example, something
like this...

<physdesc altrender="part">
  <extent>5 linear feet</extent>
</physdesc>
<physdesc altrender="part">
  <extent>2 photographs</extent>
  <dimensions>8 x 10</dimensions>
</physdesc>

...by default becomes two whole extents of "5 linear feet" and "2
photographs" and one entirely separate dimensions note of "8 x 10"

You can see how we made some of those changes here:
https://github.com/bentley-historical-library/bhl-ead-importer/blob/master/backend/model/bhl_ead_converter.rb#L259-L334

A colleague has also submitted some of these changes as a pull request
here: https://github.com/archivesspace/archivesspace/pull/312
