[Building Sakai] disable ability for instructors to enable BLTI tool from Lessons

[Keli Sato Amann]

Hi Trisha
I asked, and our developers are leaning toward option 2. I think because it's just a configuration change. However, doing that means that for every user that wants to add X tool to their site, we'd have to do it for them if they want to set it up. That's not exactly what I'd hope for--we'd want to make pre-approved tools available, already configured with a key and secret. Is that why you are leaning toward option 1?

So since it was already possible to add external tools via basic LTI, I'm not sure why it was important to add this to Lessons as well. I thought maybe it was just to allow instructors to do this themselves, but I saw this quote from Dr. Chuck, who added that to Lessons "Without Basic LTI support in Lesson Builder, we could not claim compliance to IMS CC 1.1."

Will Common Cartridge import and export not work without BLTI being part of Lessons? Or is that only if a cc that you are trying to import contains a reference to a BLTI tool that is not in your site? If you don't know, perhaps others can answer.

Hi Keli,

Thanks for raising this issue. We have similar concerns at the University of Virginia and are leaning toward your 1st option to address this concern.

Hello,
In the past, our developers had to enable BLTI tools, but it looks like Lessons allows instructors to enable and add new BLTI tools to a site on their own. We would like to disable this, as we are concerned that there may be tools created by third parties that are not responsible with student emails and info (FERPA/privacy concerns). We'd like to pre-vet tools that can be added by instructors.

There are two options for us.
1) take out Add External Tools altogether. If instructor wants a blti tool, we can add for them, or add to tools list and they can add via Site Info
2) Change default permissions of Lessons tool so that only super users can enable new blti tools in systems, but instructors can add these tools once enabled from Lessons tool.

Are there advantages or disadvantages to either?

And out of curiousity, has anyone encountered this concern, or are we being ultra conservative?
