Collections are groups of repository content that can be described themselves. Repository content is aggregated in a collection by setting the
entity reference field to point to a collection. Generally speaking, anything can behave as a collection, and anything with
field_member_of can be a member of a collection.
However, collections are 'officially' designated as such by applying the "Collection" taxonomy term to an item's
field_model field. By default, Islandora 8 has a context configured to handle collections by looking for that term.
Collections and Deleting
Collections and their members are independent of each other, and removing something from a collection does not delete it. Similarly, deleting a collection does not delete its members.
Creating a Collection
From the front page, click on Add content. This is under Tools.
Then click on 'Repository Item' to give your collection the default metadata profile for Islandora 8.
Fill out the form.
Near the end of the form, under System, select Collection from the Model drop down list.
Click Save when done.
The collection has been created. Now let's add some members to this collection.
Add Existing Items to a Collection
To populate a collection with existing items, return to any existing content and click on its Edit tab. This brings up the form for this item.
Scroll down to the bottom and the System section. In the Member of section, start typing in the name of the collection this item should belong to. Select the name of the collection you want from the autocomplete.
The correct collection is now selected. Click Save when ready.
To confirm, return to the collection and verify the new item appears in the collection's 'Members' block.
Add a New Item as a Member of a Collection
To create an item and add it as a member to a collection in one step, visit a collection and click on its
Members tab. From the
Members tab, you can manage the members of a collection and perform actions on them.
Click on the
+Add member button, and then select 'Repository Item' to give your new item a Content Type. Only content types that
field_member_of field will be available from this list.
You are taken to the creation form for a Repository Item, but if you scroll down to the
System section, you should see the widget
for 'Member Of' is already filled out for you with the appropriate collection.
Click 'Save' at the end of the form to create the new item and add it as a member to the collection.
