Adding media to nodes

Adding media from files

You can add media to existing nodes by providing a CSV file with a node_id column plus a file field that contains the name of the file you want to add:

node_id,file
100,test.txt

Values in the node_id column can be numeric node IDs (as illustrated above), full URLs, or full URL aliases.

The config file for "add_media" tasks like this (note the task option is 'add_media'):

task: add_media
host: "http://localhost:8000"
username: admin
password: islandora
input_csv: add_media.csv
# media_use_tid is optional, it defaults to "Original file".
media_use_tid: 21
media_type: file

This is the same configuration file using a term URI in media_use_tid rather than a term ID:

task: add_media
host: "http://localhost:8000"
username: admin
password: islandora
input_csv: add_media.csv
media_use_tid: "http://pcdm.org/use#Transcript"
media_type: file

If you want to specify a media_use_tid per CSV row, you can include that column in your CSV (in either "add_media" or "create" tasks):

node_id,file,media_use_tid
100,test.txt,21
110,test2.txt,35

If you include media_use_tid values in your CSV file, they override the media_use_tid value set in your configuration file.

Note

If you create an "Extracted Text" media, the contents of the specified text file will be added to the media's 'field_edited_text' field, allowing it to be indexed in Solr.

Note

The Drupal filesystem where files are stored is determined by each media type's file field configuration. It is not possible to override that configuration.

Adding references to media for use with DGI's Image Discovery module

DiscoveryGarden's DGI Image Discovery module provides a way to assign the same thumbnail image to multiple nodes. This is not the module's main purpose, but reusing a thumbnail image on many nodes is easy to accomplish using this module and Islandora Workbench.

Essentially, the Image Discovery module defines a specific Drupal field on a node, field_representative_image, that contains a reference to an existing media, for example a media with an Islandora Media Use term "Thumbnail image". This approach to defining a thumbnail is different than Islandora's normal node/media relationship, where the media entity references its parent node in a field_media_of field attached to the media.

To use Workbench to populate field_representative_image, simply include that field in your Workbench create task CSV and populate it with the media ID of the thumbnail media you want to use. The following example CSV populates the field with the media ID "3784":

id,file,title,field_representative_image,field_model
test-001,Test node 001,3784,Image
test-002,Test node 002,3784,Digital Document

Note that this approach to assigning a thumbnail image to a node does not use Workbench's additional_fields configuration setting to define a CSV column containing the filename of a thumbnail image. It simply populates a node's field_representative_image field with a media ID. DGI's module ensures that the referenced media is used as the node's thumbnail image. No other Workbench configuration is necessary.

It's just as easy to use an update task to add the referenced media ID to nodes:

node_id,field_representative_image
1089,3784
1093,3784
