Absolute paths in annotations, e.g. capabilities depending on properties of a singleton

    • Type: Improvement
    • Status: Closed
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: V4.0_ERRATA02
    • Fix Version/s: V4.01_WD01
    • Component/s: Vocabularies

    • Environment:

      Annotations

    • Proposal:
      Hide

      Extend Path syntax to allow absolute paths that start with a top-level model element (schema child).

      Natural syntax would be a path starting with a forward slash.

      Note: current "relative" paths can already start with a type-cast segment which is a qualified type name, so the / prefix or something similar is needed to distinguish "absolute" paths.

      Description

      We'd like to use a Singleton to control capabilities of an entity set, e.g. use a property of a singleton to tell whether the authenticated user is allowed to create new entities in a given entity set. This means we'd like to use a Path construct for the value of @Capabilities.InsertRestrictions/Insertable, e.g.

      <Annotations Target="My.Container/SalesOrders">
      <Annotation Term="Capabilities.InsertRestrictions">
      <Record>
      <PropertyValue Property="Insertable" Path="/My.Container/Me/Permissions/CanCreateOrders" />
      </Record>
      </Annotation>
      </Annotations>
