  • Generally, Islandora performs best with ZIP files smaller than 2 GB. If your files are larger, consider using drush with the --type=directory option.
  • Within the zip file or target directory (if using drush and the --type-directory option), each top-level directory represents a newspaper issue.
  • Files within the issue directory will become datastreams on the issue object (e.g. this is where you put issue-level metadata including a MODS file with the date of the issue).
  • Directories within the issue directory contain files that will become newspaper page objects. These are usually named numerically, as they are processed in numerical order.
  • File names must match their respective Islandora datastream IDs. This means that every page image (tiff) needs to be renamed "OBJ.tif". If you have created derivatives for the page objects, these can be named respectively (e.g. TN.jpg, OCR.txt, ...)

  • Zip file - Upload the ZIP file for batch ingest.
  • Create PDFs? - Checking this box creates a PDF derivative that contains all the pages associated with a newspaper issue.
  • Namespace for created objects - Set the namespace for the issue and page objects created for this batch ingest.
  • Generate OCR? - Checking this box causes OCR to be generated for each Page object. OCR will be attached as a datastream to each page. If checked, another option appears below it, "Aggregate OCR?".
  • Generate HOCR? - Checking this box causes HOCR to be generated for each Page object (text highlighting after full text search). HOCR will be attached as a datastream to each page.
  • Aggregate OCR? Check this box to create an OCR datastream in the issue object that aggregates the OCR datastreams from all of the page-level objects in that issue.
  • Notify admin after ingest? - Check this box to send an email to the site admin (user 1) that a newspaper batch ingest has completed. This requires the Drupal Rules module and a rule for newspaper batch notifications.
  • Ingest immediately? - Checking this box will cause the batch to go through both steps of the ingest (pre-processing and actual ingest) immediately.
    • If you do not check "Ingest Immediately", the files will be pre-processed only and added to the Islandora batch queue for an administrator to approve.
    • To approve the batch, go to Administration > Reports > Islandora Batch Sets and select "View Items in Set" next to an unprocessed set. To process the set, click "Process Set" and process all items.

If you have many ZIP files to ingest, or if the ZIP files are too large to ingest through the interface, you can also batch ingest newspapers from the Drupal command line with Drush. 

First, your file(s) need to be accessible by the Drush instance. That usually means that they need to be uploaded to the Islandora server (scp, ftp, using a mounted storage drive, etc). The "target" --scan_target option (--scan_target option in Drush 7 6 and above) is either a directory of issue directories, or a zip file of issue directories. That is, the directories representing the issues to ingest (or issue, if only one) must be one level below the directory or zip file used as the --scan_target. 

Second, preprocess the file(s). For a full list of the command-line parameters, see "drush help islandora_newspaper_batch_preprocess".  The batch options are also described in the Islandora Batch module. 

...

This will populate the queue (stored in the Drupal database) with PID entries. Note that the --parent parameter must be a newspaper title object, not an issue object or a collection object.

Here are the options in the drush command:


drush help islandora_newspaper_batch_preprocess
Preprocessed newspaper issues into database entries.

Options:
 --aggregate_ocr                           A flag to cause OCR to be aggregated to issues, if OCR is also being generated per-page.                     
 --content_models                          A comma-separated list of content models to assign to the objects. Only applies to the "newspaper issue"     
                                           level object.                                                                                                
 --create_pdfs                             A flag to cause PDFs to be created in newspaper issues. Page PDF creation is dependant on the configuration  
                                           within Drupal proper.                                                                                        
 --directory_dedup                         A flag to indicate that we should avoid repreprocessing newspaper issues which are located in directories.   
 --do_not_generate_ocr                     A flag to allow for conditional OCR generation.                                                              
 --email_admin                             A flag to notify the site admin when the newspaper issue is fully ingested (depends on Rules being enabled).
 --namespace                               The namespace for objects created by this command.  Defaults to namespace set in Fedora config.              
 --parent                                  The collection to which the generated items should be added.  Only applies to the "newspaper issue" level    
                                           object. If "directory" and the directory containing the newspaper issue description is a valid PID, it will  
                                           be set as the parent. If this is specified and itself is a PID, all newspapers issue will be related to the  
                                           given PID. Required.                                                                                         
 --parent_relationship_pred                The predicate of the relationship to the parent. Defaults to "isMemberOf".                                   
 --parent_relationship_uri                 The namespace URI of the relationship to the parent. Defaults to                                             
                                           "info:fedora/fedora-system:def/relations-external#".                                                         
 --target                                  The target to directory or zip file to scan. Required.                                                       
 --type                                    Either "directory" or "zip". Required.                                                                       
 --wait_for_metadata                       A flag to indicate that we should hold off on trying to ingest newspaper issues until we have metadata       
                                           available for them at the newspaper issue level.
