-Hi this is a prototype of an ATutor Basic LTI Integration.
-
-First check this out from
-
-https://source.sakaiproject.org/contrib//csev/trunk/atutor/basiclti/
-
-And place this into:
-
-/atutor/docs/mods/basiclti
-
-In your ATutor distribution.
-
-There is also a patch file to apply to the rest of the ATutor distro.
-
--rw-r--r-- 1 root admin 4799 Oct 25 21:39 atutor-patches-01.txt
-
-This is mostly hacking Basic LTI into the content system. This was
-not particularly elegant, I might add - I welcome a cleaner approach.
-
-Here is a video of it all working:
-
-http://www.vimeo.com/16193060
-
-Here are the steps in ATutor after the software
-(1) Install the Module from the Admin Modules Tab and Enable it
-(2) Under the Proxy Tools tab creat a new tool with the standard stuff
- http://www.imsglobal.org/developers/BLTI/tool.php
- lmsng.school.edu
- secet
-(3) Make a course. Go into content and add a new content item. Give it a title
-and then select the "Tools" tab after "Surveys and Tests" - you should be able to
-pick the prxy tool you just built. Press Save and Close and it should launch.
-
-Lots of features are not working yet, privacy, popup, height, etc. I
-needed to knock this out to start a conversation with the ATutor team.
-They will quickly come up with the right/elegant way to do this.
-
-I wanted to put it in content so it looks as much as possible like what
-I expect IMS Common Cartridge 1.1 will look like since AT already has a
-nice imscc 1.0 import.
