Save

Click the button to save all changes to the current session, or use the drop-down menu:

Reload without saving

Used to refresh the system, clearing any changes made since the last save.

Save again

Used to update the system when the Save button is disabled (useful to refresh the current connection message in case it times out).

Clear all non-required parameters

Each message parameter is tagged as being either Required, Recommended or Optional; this option will remove the values from all the recommended and optional parameters.

Start new session

This will clear the system and reset all values to their defaults.

View

Use this menu to display one of the following:

• Last service message (last service request received and the response returned)
• Gradebook (all the current line items and outcomes)
• Tool settings (any tool settings created by the Tool Provider)
• Event store (a sample store for Caliper Analytics^® event data)

Options

Open the Options form (see below).

Note that some options within the system will be disabled when settings have been changed - use the Save to resolve this.

Display optional features?

Select to show any feature which is flagged as optional; e.g., those parameters which are neither required nor recommended

Display unsupported features (but disabled)?

Select to show any feature which is defined within the LTI specifications but is not supported by this system; the feature will be displayed as disabled so that it cannot be selected

Open connections in a new window?

When selected connections to the Tool Provider will be opened in a new window rather than a page within the same window

Include empty parameters in message?

By default any parameter which does not have a value will be omitted from a message; select to include them

Only support outcomes for learners?

When selected only users with a Learner role will be enabled for the return of outcomes

Enable unpublished LTI features?

This option enables features which are still under development by IMS and subject to change

Enable experimental features?

These are extensions which are not expected to become part of the LTI specification at this time

Use this menu to change the page which is displayed.

Tool Consumer

Details of the Tool Consumer including the security profiles, services and capabilities it supports (see below)

Context/Resource

Details of the context and resource link from which the message is initiated

User

Details of the user making the connection

Message

The type of message being sent and other related parameters

Tool Provider

The URL and credentials for the Tool Provider to which messages are to be sent

Tool Proxy

When a Tool Proxy is in place, this page replaces the Tool Consumer page and shows the agreed credentials

Connection

When not opened in a new window, messages sent to a Tool Provider will be displayed on this page

Clicking on the Connect button on the Tool Provider page will cause a message of the type selected on the Message page to be sent to the Tool Provider using URL and credentials supplied on the same page. You can preview the message or override where the connection is opened via the drop-down menu.

Only those parameters on each page which have been checked will be included in the message. Service parameters for any selected service will automatically be included as well.

Custom parameter substitution variables will be replaced where an appropriate value is available (for example, $User.username).

Clicking on the Register button on the Tool Provider page will cause a ToolProxyRegistration message to be sent to the Tool Provider. The Tool Consumer Profile will include those services and capabilities which are selected on the Tool Consumer page.

When a Tool Proxy is accepted, the Tool Provider page is replaced with a copy of the Tool Proxy and a summary of the agreed credentials. The services and capabilites on the Tool Consumer will be selected based on the services in the security contract and the enabled capabilities for a resource. Any parameters required for the message type will always be selected. All others are signified by a checkbox with a shaded background - the system allows the choices to be changed but the checkbox presentation will identify which formed part of the agreed Tool Proxy.

A resource defined in the Tool Proxy should be selected from the menu provided on the Tool Proxy page. A message supported by the resource should be selected on the Message page.

A Tool Proxy can be cancelled by clicking on the Unregister button.
