This module implements a batch framework for importing books into Islandora.
The ingest is a two-step process:
- Preprocessing: The data is scanned and a number of entries are created in the Drupal database. There is minimal processing done at this point, so preprocessing can be completed outside of a batch process.
- Ingest: The data is actually processed and ingested. This happens inside of a Drupal batch.
This module requires the following modules/libraries:
Install module as usual, see this for further information.
Further documentation for this module is available at our wiki.
The base ZIP/directory preprocessor can be called as a drush script (see
drush help islandora_book_batch_preprocess for additional parameters):
Books must be broken up into separate directories, such that each directory at the "top" level (in the target directory or Zip file) represents a book. Book pages are their own directories inside of each book directory containing an OBJ and additional datastreams can be added here manually.
Files are assigned to object datastreams based on their basename, so a folder structure like:
Note: A Metadata file (*.xml OR *.mrc) and a Object file is required, all other datastreams are optional.
/tmp/batch_ingest/ └── book/ ├── 1/ │ └── OBJ.tif ├── 2/ │ ├── OBJ.tif │ ├── OCR.asc │ └── HOCR.shtml └── DC.xml
/tmp/batch_ingest/ └── book/ ├── 1/ │ ├── DC.xml │ └── OBJ.tif └── 2/ ├── DC.xml └── OBJ.tif
Either would result in a two-page book.
Each page directory name will be used as the sequence number of the page created.
A file named --METADATA--.xml can contain either MODS, DC or MARCXML which is used to fill in the MODS or DC streams (if not provided explicitly). Similarly, --METADATA--.mrc (containing binary MARC) will be transformed to MODS and then possibly to DC, if neither are provided explicitly.
If no MODS is provided at the book level - either directly as MODS.xml, or transformed from either a DC.xml or the "--METADATA--" file discussed above - the directory name will be used as the title.
Drush made the
target parameter reserved as of Drush 7. To allow for backwards compatability this will be preserved.
Drush 7 and above: (Examples of Zip and Directory batch preprocessing)
drush -v -u 1 --uri=http://localhost islandora_book_batch_preprocess --type=zip --scan_target=/path/to/archive.zip
drush -v -u 1 --uri=http://localhost islandora_book_batch_preprocess --namespace=book --type=directory --scan_target=/tmp/batch_ingest/
Drush 6 and below: (Examples of Zip and Directory batch preprocessing)
drush -v -u 1 --uri=http://localhost islandora_book_batch_preprocess --type=zip --target=/path/to/archive.zip
drush -v -u 1 --uri=http://localhost islandora_book_batch_preprocess --namespace=book --type=directory --target=/tmp/batch_ingest/
This will populate the queue (stored in the Drupal database) with base entries.
The queue of preprocessed items can then be processed:
drush -v --user=admin --uri=http://localhost islandora_batch_ingest
Custom ingests can be written by extending any of the existing preprocessors and batch object implementations.
