The Islandora Compound Object Solution Pack enables generic parent-child relationships between objects. The object view of a compound object is replaced by the view of its first child object. The included "Islandora Compound Object Navigation" block provides a thumbnail navigation of an object's siblings. A "Compound" management tab allows for the addition and removal of parent and child objects for each object.
This module requires the following modules/libraries:
This module has also the following optional requirements for certain features:
For Solr Search Integration, which allows the actual use of the 'Solr filter query' option and enables an aditional Solr Driven 'Compound Member Query' option:
- Islandora Solr Search Module
For Islandora Compound Object JAIL Display:
- JAIL JQuery library
Install as usual, see this for further information.
If utilizing the lazy loading image ability of the solution pack, the JAIL JQuery library must be present within sites/all/libraries/JAIL.
Set the 'Child relationship predicate' and 'Solr filter query', as well as display options in search results and derivative creation options in Administration » Islandora » Solution pack configuration » Compound Object Solution Pack (admin/islandora/solution_pack_config/compound_object).
The 'Redirect to first child when a compound object is requested' option skips the Islandora generated parent object display by redirecting, via HTTP, to the first visible child of a compound ensemble.
Optionally, enable the JAIL compound block to utilize the lazy loading image ability using Javascript by checking 'Use alternative, alternative dsiplay for compounds' as shown below.
If the Solr Search Module is enabled, an additional Compound Member Query Option and a new 'Solr Backend' Menu tab will be shown at Administration » Islandora » Solution Pack Configuration » Compound Object Solution Pack (admin/islandora/solution_pack_config/compound_object/solr)
Block:
There exist two block options for displaying compound objects within Islandora. The default "Islandora Compound Object Navigation" block will provide navigation controls and loading of all objects related to the parent compound. The latter option is a block utilizing the JAIL library which allows for lazy loading of images. This allows the block to load images only when they are being accessed which will greatly increase performance on compounds with many children.
Theme:
The "Islandora Compound Object Navigation" block can be themed. See theme_islandora_compound_prev_next().
Drush:
A Drush command has been added, to be run from the command line (Terminal), that will update the existing rel-predicate of existing compound objects to isConstituentOf. It can be run with the drush command drush update_rels_predicate. This command accpets no arguments.
