Content Types and Hierarchy

Content Types and Hierarchy#

The udala.tablon package provides three custom Dexterity content types to structure the Electronic Notice Board in Plone. This architecture is strict to ensure valid data models are presented to citizens and APIs.

1. Tablon (Notice Board)#

  • Role: The container/folder that acts as the root of the Notice Board.

  • Hierarchy Rules: Tablon allows only DocumentoTablon objects to be added as children.

  • Visibility: Typically placed at the root of the site (for example, /tablon).

2. DocumentoTablon (Announcement Document)#

  • Role: Represents a single administrative announcement or publication.

  • Hierarchy Rules:

    • Cannot be added globally. Must be created inside a Tablon.

    • Allows only AcreditedFile objects to be added as children.

  • Fields:

    • origin: A mandatory Choice field restricted to "internal" or "external". It defines whether the document was generated by the organization itself or by an external body (like a higher-level government).

    • origin_department / origin_details

    • publication_url: Optional link to the original publication source (like an Official Gazette).

3. AcreditedFile (Accredited File)#

  • Role: An uploaded binary file (for example, PDF) that requires an external digital certificate or timestamping for legal verification.

  • Hierarchy Rules: Cannot be added globally. Must be created inside a DocumentoTablon.

  • Fields:

    • file: The NamedBlobFile containing the actual binary data.

    • url: A backend-managed URL linking to the generated external accreditation certificate.
