@hsinkoff I left a couple of small comments but this generally looks good. Do you want to take a pass through this before we push this out of draft and open it up for general review?

When in the same repo, we should link to the local version of the document so that local builds don't accidentally point to the deployed docs.

Implicit roles grant users permissions, but are not specifically assigned

I think it would be useful to move the Best Practice section above this overview since that is meant to replace these other ways of managing permissions. I think it would also be helpful to be more clear that these tactics should be avoided unless there are very good reasons not to do this.

@feanil Yes, give me 24 hours to make the updates first.

One more day for general review, then I'll do a final review to figure out if there are any changes needed before we can merge this.

This looks really great - thanks for the hard work on this, everyone. I added just a couple questions and some style notes (particularly, "Open edX" is an adjective per our trademark guidelines).


There are a variety of manners in which authorization is handled within the Open edX ecosystem.
The goal of OEP-66 is to provide best practices that should be used with all the
systems/protocols and outline the currently in use systems/protocols.

Best Practices Motivation

unified documentation on the systems/protocols. This OEP aims to compile existing
knowledge and documentation into a central document that will give an overview of each
system/protocol. The aim is not to be the only source of information for each system/protocol,
but rather a starting point when learning about authorization within Open edX.

"Open edX" should be used as an adjective

it can be difficult to avoid accidentally changing other permissions with
a similar implementation.

This title confuses me and I don't know what even to suggest. Is it something like, "Currently Used Systems/Protocols"?

is there a reason django is lowercase in this section but uppercase previously?

In this way, it can grant permissions to a user that they will not be able to use.

Implicit roles don't seem... good? I understand this is just a definition section, but this definition leaves me scratching my head about the "why" this would possibly exist in a system

@hsinkoff: Apologies that I forgot about this and can't immediately get to a detailed review. I understand that that means this will land without that, which is completely fine. Another general comment is that there might be some definitions or details that are noted in https://openedx.atlassian.net/wiki/spaces/AC/pages/935919751/Authorization that might be helpful. For example, what is a "system-wide role" and what are examples? What is a super user, and global staff, etc.? Something to consider. We discussed this doc in the past, so maybe you've already captured everything you wish to.

Thank you for bringing in some updates from my examples from https://openedx.atlassian.net/wiki/spaces/AC/pages/935919751/Authorization. Rather than me going through each point, I'd like to ask my question in a different way...

Once this OEP lands, would you feel comfortable archiving the above Confluence doc with a note that reads that its contents are now represented in OEP-66. If the answer is yes, great. If the answer is no, please consider moving in whatever gaps you find.

Also, maybe you can respond with a comment as well, if needed. For example, do you think the diagrams in that document are redundant, or unclear, or misleading, or unhelpful?

I'm hopeful that this OEP can replace older Authorization related documentation, which is why I ask. This is what I did with legacy Authentication related documentation when creating the AuthN OEP.

Thank you. Also, I don't have really strong opinions because my head is not in that space. @iloveagent57 made edits to that page, so maybe he has stronger opinions?

One additional diagram, along with text describing the diagram, and key take-aways from it have been added to the OEP. With this addition, I think the OEP will allow for archiving https://openedx.atlassian.net/wiki/spaces/AC/pages/935919751/Authorization

Can you provide a link to the diagram source as well?

The diagram was created specifically for this OEP.

It is based on one in https://openedx.atlassian.net/wiki/spaces/AC/pages/935919751/Authorization, but with a few modifications aimed at highlighting certain use cases. The changes are significant enough that I don't think we'd want to link to that diagram as the source.

Right. I meant the source of the new png. How was it created, and what happens if someone wants to update it? (Same might be true of other diagrams.)

From OEP-19:

Exported Diagrams. In order to keep diagrams updated across time, they will need to be exported from whichever tool they were created in, with the exported version maintained in GitHub.

  • draw.io diagrams will be exported and imported as XML files.
  • Lucidchart diagrams will be exported and imported as Visio (VDX) files.

I've re-worked the diagrams in order to ensure they are editable in the future. I've also separated the data tables by diagram. Please take a look when you have a chance.

Looks like all comments have been addressed and I see no major issues. I'm marking this OEP as accepted and will merge it shortly.
