DKAL

..and as i was about to abandon the field of Grid authorisation languages, yet another grammar comes along. I was convived that there was no life after SecPAL and that the technology had pretty much covered all the Grid requirements for access control. That was up until last week when I came across DKAL (distributed knowledge authorization language)...DKAL claims to be more flexible than SecPAL by extending the number of predicates and action verbs and by adding another set of deduction rules in the way an authorization request is evaluated. I have to say as a close associate of SecPAL that it is really fascinating and as the authors claim it DKAL could be an add-on or an extension to SecPAL. A short
IEEE paper is here and a longer technical report can be found here
