Hi!

ODRL allows you to define so-called Privacy policies [1]: "A Policy that
expresses a Rule over an Asset containing personal information." which
would contain permissions & prohibitions tied to your PI.
For example, such a policy could in ODRL be expressed like this:
<http://example.com/policy:42>
a odrl:Privacy ;
odrl:permission [
a odrl:Permission ;
odrl:target ex:asset_9898 ;
odrl:action odrl:reproduce ;
odrl:assigner ex:Alice ;
odrl:assignee ex:Bob ;
odrl:duty [
a odrl:Duty ;
odrl:action odrl:obtainConsent ;
odrl:output ex:Consent ;
odrl:consentingParty ex:Alice ;
odrl:consentedParty ex:Bob ;
]
] .
Resembling a permission Alice has granted to Bob for reproducing her PI
(denoted as asset_9898) under the condition that Bob obtains Alice's
consent.
https://www.w3.org/TR/odrl-vocab/#term-consentingParty - party to obtain
consent from
https://www.w3.org/TR/odrl-vocab/#term-consentedParty - party who
obtains the consent
https://www.w3.org/TR/odrl-vocab/#term-obtainConsent - To obtain
verifiable consent to perform the requested action in relation to the
Asset.
https://www.w3.org/TR/odrl-vocab/#term-output - specifies the Asset
which is created from the output of the Action.
However, ODRL does NOT define:
1) HOW & WHEN consent has to be obtained, i.e., HOW & WHEN fulfillment
of the duty has to be verified/checked
2) HOW consent has to "look like", i.e., what information ex:Consent has
to contain
