==== xoRBAC ====
Neumann and Strembeck discuss the design and implementation of an RBAC service xoRBAC in an object-oriented scripting language XOTcl [[http://orbit-lab.org/attachment/wiki/Internal/Rbac/RbacResources/neumann01design.pdf NS01]] and implementation of conflict checking of separation of duty constraints in RBAC [[http://orbit-lab.org/attachment/wiki/Internal/Rbac/RbacResources/se2004.pdf Str04]].  See [[http://wi.wu-wien.ac.at/home/mark/xoRBAC/index.html xoRBAC]] for downloadable software.  Neumann and Zdun introduce the object-oriented scripting language XOTcl which is based on Tcl in  [[http://orbit-lab.org/attachment/wiki/Internal/Rbac/RbacResources/neumann00xotcl.pdf NZ00]].

Strembeck describe the application programming interface (API) for xoRBAC in [[http://orbit-lab.org/attachment/wiki/Internal/Rbac/RbacResources/xoRBAC-API-Reference.pdf Str06]].
