Re: [ecf-dev] Shared Editor Usage Scenarios


  Interesting...thanks for your response!  So in your situation, where students may be in a variety of places, connecting via various ways (campus network, dial up, etc.) how do you see students creating/connecting to a shared ECF instance?  Are the current ECF scenarios of creating a shared session sufficient for you and your students?

  Regarding shared editing, do you see a free-for-all model working best?  Do you think more explicit control over who can edit is important?

  One thing that strikes me from your example is that the TA/Instructor in this case cannot count on having the same project/file in their workspace.  Students will create arbitrary project structures.  Due to this it makes sense (at least in this use case) to have project synchronization occur before shared editing begins.  Naturally, this would exist as a new project wizard, in which files from remote peers would be transferred locally.  After the shared session ends, the project could safely be deleted, etc..

Let me know what you think...

One of the reasons I want a shared editor in the collaborative environment we're building, based upon ECF, is that in such situations I, or one of my TAs, can establish a session with the student to see exactly what they're trying to do, have them explain it while they show me, and then to possibly insert code into the file so they can get started on the right path.

Subject: [ecf-dev] Shared Editor Usage Scenarios


  I've been thinking about various ways groups might use shared editing.  My initial (base) use case was a distributed development team, perhaps in a design meeting or doing code review.  However I can think of a few other scenarios.  These scenarios also imply better sharing models:

1. Instructor use case.  In an education context, one peer may have exclusive write access to an editor, others would be read only.  Additionally, file open/close actions on the instructor node would propagate to "student" nodes.
2. Document collaboration use case: A document (rtf, etc.) is being edited by a group.  Higher levels of locking semantics are required, as these people are not developers (or even if they are) and may be confused by free-for-all shared editing.
        a) A token style workflow, where the user with the token can edit, and can also pass the token to other users in the collaboration context.
        b) A lock style workflow, where a user locks a portion (paragraph?  line item?) of a document.  Others cannot edit until locker unlocks.

Any thoughts?  Any other use cases people can think of?  I may work on implementing these in the shared editor if they seem of value to others.
