      Structured access information for heritage collections, services, or facilities.
      **Purpose**:
      Replaces simple string descriptions of access conditions with structured
      data capturing access types, eligible users, conditions, and restrictions.
      **Key Properties**:
      - `has_or_had_type`: Type of access (PUBLIC, BY_APPOINTMENT, RESTRICTED, etc.)
      - `has_or_had_user_category`: Who can access (public, students, faculty, researchers)
      - `condition_of_access`: Conditions or requirements for access
      - `has_or_had_description`: Free-text description
      - `temporal_extent`: When this access policy applies
      **Access Types**:
      - PUBLIC: Open to general public
      - BY_APPOINTMENT: Requires advance appointment
      - ACADEMIC: Restricted to academic community
      - RESEARCHER: Restricted to credentialed researchers
      - MEMBER: Requires membership
      - RESTRICTED: Limited access with specific conditions
      - CLOSED: Not currently accessible
      - DIGITAL_ONLY: Available only in digital form
      **Ontological Alignment**:
      - **Primary**: `dcterms:RightsStatement` - Dublin Core rights statement
      - **Close**: `schema:publicAccess` - Schema.org access indicator
      - **Related**: `crm:E30_Right` - CIDOC-CRM rights
