RE: Party: Assignee=everyone

Hi

1/ As we don't want to always tie this to a specific @uid, is the following correct?
a/  Change type from 'set' to 'offer'
b/ omit o:party[ @function="ov:assignee ]
<!--
Scenario: The EPA {assigner} allows anyone {assignee} to distribute {action} a picture {target-asset} in Germany {constraint}.
So as an Offer this then becomes:
-->
<o:policy uid="http://epa.eu/cv/policy/1" type="http://w3.org/ns/odrl/vocab#offer" xmlns:o="http://w3.org/ns/odrl/2/" xmlns:ov="http://w3.org/ns/odrl/vocab#" xmlns:rml="http://iptc.org/std/RightsML/2011-10-07/" xmlns:p="http://example.com/RightsML/vocabulary/proprietary1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://w3.org/ns/odrl/2/ http://www.iptc.org/std-dev/RightsML/1.0EP/specification/ODRL_2.0.xsd">
   <o:permission>
      <o:asset uid="urn:newsml:epa.eu:20090101:120111-999-000013" relation="ov:target"/>
      <o:action name="rml:distribute"/>
      <o:constraint name="http://w3.org/ns/odrl/vocab#spatial" operator="ov:eq"
       rightOperand="http://cvx.iptc.org/iso3166-1a3/DEU"/>
      <o:party uid="http://g2.dpa.com/cv/dpaparty/epa" function="ov:assigner"/>
   </o:permission>
</o:policy>

2. Agreement / scope

> If you actually want to say "everyone", there is the @scope attribute [1] with value "all", but usually needs a context (via @uid).

For an agreement: If an assignee (with @uid) is added, is scope=all explicitly needed? Or does the absence of party /@scope implicitly mean 'all people in the context of the party defined by party /@uid'?

Many thanks

When you leave out the Assignee, then you are making no statement as to who that is.
This is typically ok for the Offer policy type (for example).

If you actually want to say "everyone", there is the @scope attribute [1] with value "all", but usually needs a context (via @uid).

However, if you are just making an "Offer" then leaving out assignee is fine....if you want to express an "Agreement" then you may need to define a uid for your context.
