README

Show a LTI tool resource (f.e. a moodle course) with TYPO3 as LTI platform.

Implementation for the "TAO - LTI 1.3 Core Library" https://github.com/oat-sa/lib-lti1p3-core LTI 1.3 specification: https://www.imsglobal.org/spec/lti/v1p3/

Content Elements

You can use two different content elements, "Button" and "iFrame". Both elements need a logged in frontend user!

The frontend user will get an account in the LTI tool via oauth2 and oidc, if he uses the element the first time. Then he gets logged in at the LTI tool and can use the resource.

The value for the field "LTI Resource" in the TYPO3 content elements comes from the LTI tool.

Moodle: Edit course / More / Published as LTI tools / Launch details / Custom Properties / id=xxx-xxx-xxx-xxx-xxx-xxx Use the "xxx-xxx-xxx-xxx-xxx-xxx" in the TYPO3 content element's field "LTI Resource". Deep Linking is not implemented!
