Schema

Signicant objects in the system:

1. Course (django_courseaffils)
   • connected to a (django) Group for members, and another Group for faculty
   • session-based course selection
2. Asset (./assetmgr ) represents a media object available on the web.
   • connects to a specific Course (ForeignKey)
   • An asset has many Source urls
   • has one TextField() for a metadata blob (in json)
3. SherdNote (./djangosherd ) an annotation referencing an Asset (and owned by a User)
   • when the range* fields are NULL, then it’s an annotation on the whole asset.
4. Project (./project ) an essay with a big TextField for the body
   • also has participants for collaboration ( ManyToManyField(User) )
   • embedded annotations are simply A-tags with class=“materialCitation”
   • Projects are versioned with modelversions
5. Discussion (threadedcomments)
   • embedded annotations are done the same way here: A-tags with class=“materialCitation”
