islandora_text_extraction
Connects Islandora 8 to Hypercube microservice and extracts text from PDFs
Install module in the usual way,
then copy assets/ca.islandora.alpaca.connector.ocr.blueprint.xml
to /opt/karaf/deploy on the server.
note: This config file assumes a url of http://localhost:8000/hypercube.
If your service is found elsewhere this must be changed.
There is no need to restart.
In the usual Ansible build this will require no modification.
If a parent node is tagged as Digital Document an Image tagged media
will extract text from that image at the time of ingestion.
The content type of the parent node should be configured to allow multiple tags.
note: Media are linked to their parent nodes with the Media Of
entity reference field. If you wish to attach the PDF (or any other ) media type
to a parent node which has any content type other than Repository Item
(islandora_object) the parent content type will have to be added to the Media Of
field in the media type description.
Prepare module for PDF text extraction
Install texttopdf on your server if not already present.
On an ubuntu/debian machine like the default claw playbook run
sudo apt-get install poppler-utils
test to see its been properly installed with which pdftotext
Install php libraries with composer require spatie/pdf-to-text
In the unlikely event that your pdftotext binary exists on your server
outside of the system path, the path to the binary can be set at
/admin/config/islandora/text_extraction.
Using text extraction
The containing document must be tagged as Digital Document,
and the media must be tagged as Original File.
A new editable Extracted Text media will be created and attached when PDF or
Image media types are added to a node.
