Hello All,
IMHO, the term "hierarchical" is not clearly defined in jetspeed. There is more than
one meaning for hierarchical roles/groups according to
http://www.doc.ic.ac.uk/~ecl1/papers/rbac99.pdf.
For example, there're 3 hierarchical roles:
-R1
--R1.1
--R1.2
with persmissions:
grand R1 { permission P1 }
grand R1.1 { permission P2 }
grand R1.2 { permission P3 }
By a generalisation hierarchy ("is a"-hierarchy):
R1 has [P1]
R1 has [P1,P2]
R1 has [P1,P3]
and by a agrregation hierarchy ("part of")
R1 has [P1,P2,P3]
R1 has [P2]
R1 has [P3].
What type of hierarchy will be supported? Does it make any sence to support different
types?
Regards,
Artem
