[osee-dev] The Concept of Undelete

Developers,

A number of use cases have been identified that appear to involve the concept of undelete.  These cases are:
   1.  a user deleted an artifact and then wishes to undo the deletion:  currently handled using revert which is less than ideal since it leaves no history of its occurrence
   2.  same as case 1 but for a relation - this case has the additional implication of needing to preserve the relation identity to aid in conflict detection
   3.  same as case 1 but for an attribute

A related case that does not involve deletion is when a user wishes to go back to a previous version of an attribute.

This brings up the question of what modification type(s) would be used in the osee_txs table for such cases.  Also how will this be conceptually presented to the users.

Thanks,
Ryan Brooks
