Export Date Management - wvulibraries/mfcs GitHub Wiki

The export table allows MFCS to only export digital objects that have been added or modified since the last export. On large collections this is beneficial so that the digital asset download isn't excessively large.

However, sometimes this can cause digital items to not load. This is usually because there are a large number of items requiring considerable time to transform (such as many records with large number of tiffs going through an OCR process). If an export occurs before all the items for a form/project have been transformed they will not be exported and their modified date will be before the last export.

To get around this we sometimes need to "back up" the export date for a form or project. This will result in some duplicate exporting of digital objects but it will also "catch" any that were missed.

When deleting export dates please only delete back as far as needed (usually only the last one).

Removing archival export dates will not have a negative impact on the system, as long as the newest "Good" one is in place.
