Outcome

• not discussed, MPDL got out of Internet :)

create new role &issues with default filter conditions

• how to create a new role in the core-service with a policy that does not refer to the core service resources?
• e.g.
  • created new policy with scope

        <role:scope unlimited="false">
		<role:scope-def resource-type="cone-service"/>
	</role:scope>

• • first case: provided very dummy policy that applies to schema, however no login of any user was possible afterwards
    • after deletion of all related data users could log-in
  • second case: provided policy with action to retrieve contexts only
  • granted this role to the user
    • when filtering for items - situation is changed -> rules which apply to default user are not simply applied, they are extended and user gets much more items then actually needed
      • the user to which this role is assigned is member of 2 user groups (with no privileges at all)
      • the following query in filters is applied (note: commented out part is most probably problematic)
      • with uncommented part user gets ca.2947 items (as it only checks for existence of privilege basically)
      • with commented part user gets ca.391 items

SELECT r.id FROM list.item r WHERE (
  (
    (
      (
        (
          r.id IN (
            SELECT resource_id FROM list.property WHERE local_path='/properties/version/status' AND value='released'
          )
        )
      )
    )
  /*  OR (
      (
        r.id IN (
          SELECT resource_id FROM list.property WHERE EXISTS (
            SELECT object_id FROM aa.role_grant WHERE user_id='escidoc:102002' AND role_id='escidoc:107021' AND (
              revocation_date IS NULL OR revocation_date>CURRENT_TIMESTAMP
            )
            AND (
              object_id IS NULL OR object_id=r.id
            )
          )
          OR r.id IN (
            SELECT resource_id FROM list.property WHERE EXISTS (
              SELECT object_id FROM aa.role_grant WHERE (
                group_id='escidoc:107001' OR group_id='escidoc:107006'
              )
              AND role_id='escidoc:107021' AND (
                revocation_date IS NULL OR revocation_date>CURRENT_TIMESTAMP
              )
              AND (
                object_id IS NULL OR object_id=r.id
              )
            )
          )
        )
      )
    ) */
  )
)
AND (
  r.id IN (
    SELECT resource_id FROM list.property WHERE local_path='/properties/context/id' AND value='escidoc:persistent3'
  )
)
LIMIT 1000

Outcome

• filters not discussed
• Role creation
  • would make sense to create roles which are also valid for external services such as CoNE
    • external services would then have to make own PDP based on the rights provided with AA Roles and privileges
    • has to be thought properly, as also grants can be made on external objects
    • initial idea: external roles (tag a role with additional property), external grants (tag a grant with additional property)

batch update of resources

• discuss the possibilities
  • envisioned use case:
    • user browses many images and filters them e.g. by date of creation, part of the name (simple case: all images are released, therefore searchable)
    • user selects certain number of images e.g. 500 and wants to add them metadata "place=Paris"
    • quick update of images is there ...

outcome

• Would be good to provide use cases and scenarios
• Input after VidConf: Faces_4.0

others

• eSciDoc-Colab Page setup
• Alignment of tools and processes (e.g., Maven)
• Improved and harmonized communication of eSciDoc
