This page details the functionality related to the modification of collection assets.
Overview
A collection is an ordered set of assets. There are multiple scenarios related to modifications of collections.
The linked assets get modified
New assets are added to a collection
Existing assets are removed from the collection
Metadata of the collection is modified
A collection can also be trackable or non-trackable, and assets within them also may be trackable or non-trackable within the collection. Certificates may also be attached to trackable collections.
This page details the system behavior in these different scenarios.
Trackable Collections
Examples of trackable collections are Courses and Programs. In addition courses also typically have certificate attached to them. Following sections detail the functionality related to trackable collections.
Linking asset to a collection
When an asset is linked to a trackable collection, there should be an option to specify if the asset is trackable as part of the collection or not.
Modification of collection
Once a trackable collection is published, the collection can be modified. Following has to be taken care when modifying a collection
Modifying the metadata of collection is allowed
Adding a new asset to the collection is allowed
Removing an asset from the collection is NOT allowed
Updating the version of a linked asset is NOT allowed in case the asset is set as trackable in the collection, when linking to the collection.
Updating the version of a linked asset is allowed in case the asset is not set as trackable
Deleting a collection
A trackable collection once published cannot be deleted.
Adding certificate
Adding a certificate to a trackable collection doe not happen during the creation of the collection and hence not part of the sourcing flow. The option of specifying when to issue a certificate should be part of adding certificate and not part of creation flow.
Non-trackable Collections
Digital Textbooks, Playlists are typically non-trackable collections.
Linking asset to a collection
When an asset is linked to a non-trackable collection, there should NOT be any option to specify if the asset is trackable or not.
Modification of collection
Once a non-trackable collection is published, the collection can be modified. Following has to be taken care when modifying a collection
Modifying the metadata of collection is allowed
Adding a new asset to the collection is allowed
Removing an asset from the collection is allowed
Updating the version of a linked asset is allowed
Deleting a collection
A non-trackable collection can be deleted.
Common Functionality
This section details the common functionality across trackable and non-trackable collections.
Modification of an asset linked to a collection
When an asset is published, system checks if any collection is pointing to this learning asset. If so, while approval, it shows a dialog saying “This is currently linked to one or more collections. Please republish the collections to reflect the new version in the collection”. The dialog should show the list of collections (names and ids in sourcing repo) to which the learning asset is linked to.
When an asset linked to a collection (trackable or non-trackable), is published, the new version of the asset should NOT automatically get linked to the collection.
For a collection to reflect the new version - the collection has to be modified, the newer version is explicitly updated and collection republished.
When a collection is getting edited, in case there are newer versions available for some of the linked assets, the editor should indicate the same. There is an option to update to the latest version.
As described in the previous section, version update can only happen in case the asset is non-trackable in the collection.
Deleting an asset linked to a collection
If an asset is linked to one or more collections, the asset cannot be deleted. The user is given an appropriate message with the list of collections to which the asset is linked.
