example - a policy representing for agent delegation #112
Description
This example aims to showcase a possible representation for agent delegation of a "state of the world" (which is composed of the state and ODRL policies) for an assignee ("userID") by making the state of the world an odrl:Asset implicitly and therefor being the target of odrl policies:
ex:actionNode a odrl:Action ; // agent has access to the action odrl:read
rdf:value odrl:read ;
rdf:refinement ex:actionRefinement .
ex:actionRefinement a odrl:Constraint ; // constrained to 3 executions of the action
odrl:dataType xsd:int ;
odrl:leftOperand odrl:Count ;
odrl:operator odrl:lteq ;
odrl:rightOperand 3 .
ex:constraintExample a odrl:Constraint ; // constrains up to the end of 2025
odrl:datatype xsd:dateTime ;
odrl:leftOperand odrl:dateTime ;
odrl:operator odrl:lt ;
odrl:rightOperand "2026-01-01T00:00:00.0000000Z"^^xsd:dateTime .
ex:permission a odrl:Permission ;
odrl:assigner ex:userID ; // for delegation the assignee becomes the assigner
odrl:assignee ex:agentID ; // the agentID becomes the assignee
odrl:target ex:stateOfTheWorldID ;
odrl:action ex:actionNode ;
odrl:constraint ex:constraintExample . // constrain the permission.
ex:stateOfTheWorldID a odrl:Asset, tbd:StateOfTheWorld . // here is the SoWIn practice, it is desirable to fine-grain the allocation of each action (ie. logical constraint [ count AND expiry ] and include the functions that the agent can take in the policies within the SoW) to prevent the spawning of rules, in http & json (simplifying for representation):
request
PATCH /api/v1.0/Agent/{userID}/delegate
payload
{
"target": "ex:stateOfTheWorldID",
"assignee": "ex:agentID",
"function": "odrl:Assignee",
"actions": [
{
"expiry": 1767229200, // = 2026-01-01T00:00:00.0000000Z it can be a date, but epochs are better for efficient computation
"action": "odrl:read",
"count": 3
}
]
}The management/administration plane (red below) is where this policy is created:

@joshcornejo, thank you for sharing the example. It is also relevant for the section on norms and policies in the WebAgents CG interoperability report. I will add a pointer to this issue.
@gnardin might also be interested in this example.

@andreiciortea / @gnardin - just remember this part of the flow is "post authentication", any questions let me know.
