• The API should look as follows:

  • historyService.setAnnotationForOperationLogById("foo", "annotation");
    historyService.clearAnnotationForOperationLogById("foo");
    

  • The annotation can be retrieved via querying the user operation
• When a user operation log consists of multiple entries, the annotation should be present on each entry (this is consistent to the other attributes)
• Annotating a user operation log should in turns produce a user operation log; Like this one can audit who changed / added an annotation
• Authorisation Check
  • Introduce UPDATE permission on resource "User Operation Log Category"
  • Introduce UPDATE_HISTORY permission on resource "Process Definition"
• Column ANNOTATION_ is of type VARCHAR(4000)
