-"""An interface for publishing rich data to frontends.
-
-There are two components of the display system:
-
-* Display formatters, which take a Python object and compute the
- representation of the object in various formats (text, HTML, SVG, etc.).
-* The display publisher that is used to send the representation data to the
- various frontends.
-
-This module defines the logic display publishing. The display publisher uses
-the ``display_data`` message type that is defined in the IPython messaging
-spec.

- A dictionary having keys that are valid MIME types (like

- that MIME type. The data itself must be a JSON'able data
- structure. Minimally all data should have the 'text/plain' data,
- which can be displayed by all frontends. If more than the plain
- text is given, it is up to the frontend to decide which
- representation to use.
- metadata : dict
- A dictionary for metadata related to the data. This can contain
- arbitrary key, value pairs that frontends can use to interpret
- the data. Metadata specific to each mime-type can be specified
- in the metadata dict with the same mime-type keys as
- the data itself.
- source : str, deprecated
- Unused.
- transient : dict, keyword-only
- A dictionary for transient data.
- Data in this dictionary should not be persisted as part of saving this output.
- Examples include 'display_id'.
- update : bool, keyword-only, default: False
- If True, only update existing outputs with the same display_id,
- rather than creating a new output.
