Administrating ILIAS as an LTI-Provider

1 Initial Problem

ILIAS does not support the Learning Tools Interoperability (LTI) standard. This article focuses on ILIAS becoming a LTI Tool Provider according to LTI 1.1.

2 Conceptual Summary

Administrating ILIAS as an LTI tool Provider finds a new home in the general Administration Panel.
The new node will show the following tabs:

• Consumers
• Permissions

3 User Interface Modifications

3.1 List of Affected Views

• Dropdown for opening Main Administration Panel 

3.2 User Interface Details

The Dropdown for opening Main Administration Panel gets a new LTI entry. 

A new administration folder is added for the global LTI settings in ILIAS. This folder has the tabs Consumers and Permissions.

The Consumers tab has a table of globally defined credentials for Tool Consumers. Consumers can be added, edited de/activated and deleted. For each consumer the following settings can be configured:

• Title (required): a title for the tool consumer
• Description: an optional description for this tool consumer
• Prefix (required): a prefix for the username. New ILIAS account will generate usernames with the folowing pattern: CONSUMERPREFIX_USERNAME[COUNTER_IF_NOT_UNIQUE]
• Consumer Key: is defined on object level
• Consumer Secret (required): is defined on object level
• Language: Default language for generated LTI user accounts.
• Active: De/Activation of consumer
• Object Types: A list of object types which are available for this consumer. Nevertheless, instances of the activated object types must be enabled in the object settings.
• Global Role (required): the global role new ILIAS-LTI accounts are assigned to.

The Permissions tab offers access to the LTI-Node in the Administration panel.
A new permission "LTI Administration in Objects" will be introduced. Users with this permission have the possiblity to enable the LTI service for consumers in the object settings.

7 Discussion

JourFixe, ILIAS [jourfixe], July 24, 2017: We highly appreciate this suggestion and schedule it for 5.3 (assumed ILIAS as LTI tool provider is accepted in general). We would like to have the following changes / extensions:

• Secret should be created by ILIAS and not manually
• An overview similar to "Released Courses" in ECS should be offered in the LTI administration

JourFixe, ILIAS [jourfixe], July 31, 2017: After acceptance of New Objects-Settings for LTI-Provider this feature request can be scheduled for 5.3.

8 Implementation

The Administration of the LTI-Provider was implemented as described at ‘User Interface Modifications’.
In addition all objects used by LTI are listed at ‘Shared Objects’:

It is recommended to create global roles specifically for LTI to adjust rights and to restrict access to full repository path.
