HOWL Update 1.1.104

{{#eclipseproject:technology.higgins}}

Higgins logo 76Wx100H.jpg

Version 1.1.104

Changes

  1. On the higgins call of July 3rd 2008 it was agreed that we should drop the experimental "managedBy" approach introduced in 1.1.103 in favor of a "recursive" approach where we simply use PolicyEntities to control access to PolicyEntities
    • managedBy attribute has been deleted
  2. On Access Control in IdAS page we agreed to define a Policy class and an AccessControl subclass of Policy. This has now been done.
  3. Added higgins:part attribute (and its inverse higgins:partOf)
  4. Added higgins:member to be the inverse of the existing higgins:memberOf
  5. Added a groupSubject sub-Attribute of higgins:subject
    • The attribute's value must be a higgins:Group and the subject is any member of the stated Group (or any sub-Group of that Group)
  6. Added a selfInstanceSubject sub-Attribute of higgins:subject.
    • If the current IdAS consumer exists as an EntityId E within this Context AND if E is an instance of the range of this property, then the subject of the Policy is E.
  7. Added a onAttribute sub-attribute of higgins:accessControl
    • If present on an Access Control Policy the policy is restricted to apply only to the type of attribute indicated by the range of this relation within the Entity or set of Entities indiated by this Policy's :operation relation.
