Only erratum #303 was discussed
https://github.com/w3c/poe/issues/303

Options a) and b) from Michaels email
https://lists.w3.org/Archives/Public/public-odrl/2020Jun/0003.html were
discussed as well as a third option detailed by Michael in Issue #10 <
https://github.com/w3c/odrl/issues/10> https://github.com/w3c/odrl/issues/10


Details of subclassing "golden three" (Permission, Prohibition, Obligation)
were discussed with focus on processing requirements for "consequence"
properties of a Duty https://www.w3.org/TR/odrl-model/#duty
Consensus was that the "consequence" property is optional (cardinality
zero, one, or more) and a Profile may define a more suitable
consequence-like property in its own Duty subclass if necessary and without
violating the current ODRL provisions.
According to Michael, there might be other possible subclassing issues that
were not discussed.

David stated that there seems to be insufficient technical input from
experts to warrant change to a major normative provision of the current
(2.2) ODRL Information Model Recommendation
https://www.w3.org/TR/odrl-model/#policy
Ben also advised to be conservative on this issue. Michael proposed to
implement option a) in the Profile BP document
https://w3c.github.io/odrl/profile-bp/
encouraging maximum reuse of "golden three" before subclassing or adding
Rule subclasses that are not "golden three" subclasses. Michael will
encourage the CG expersta and the wider implementer community to provide
feedback, especially if they have trouble fulfilling the Policy class
requirement to use at least one of the "golden three".

UPM representatives requested prioritizing UPM DUC-ODRL presentation for
the August 3 meeting.

Actions:
1) Michael to edit Best Practice document to reflect option a) and issue a
call for dissent to implementers
2) Renato to schedule UPM DUC-ODRL presentation as a priority item for the
August 3 call

Meeting adjourned 12:58 UTC
