-Abstract
-========
-
-This specification is a Zarr protocol extension defining a data type where each
-element is an arbitrary Python object.

-Status of this document
-=======================
-
-This document is a **Work in Progress**. It may be updated, replaced
-or obsoleted by other documents at any time. It is inappapropriate to
-cite this document as other than work in progress.
-
-Comments, questions or contributions to this document are very
-welcome. Comments and questions should be raised via `GitHub issues
-<https://github.com/zarr-developers/zarr-specs/labels/object-dtypes-v1.0>`_. When
-raising an issue, please add the label "object-dtypes-v1.0".

-Document conventions
-====================
-
-Conformance requirements are expressed with a combination of
-descriptive assertions and [RFC2119]_ terminology. The key words
-"MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
-"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in the normative
-parts of this document are to be interpreted as described in
-[RFC2119]_. However, for readability, these words do not appear in all
-uppercase letters in this specification.
-
-All of the text of this specification is normative except sections
-explicitly marked as non-normative, examples, and notes. Examples in
-this specification are introduced with the words "for example".
-
-
-Object data types
-=================
-NumPy's object arrays are arrays where each element is an arbitrary Python
-object. The array elements correspond to the
-`numpy.object_ <https://numpy.org/doc/1.22/reference/arrays.scalars.html#numpy.object_>`
-type which has character code `'O'`. A common concrete use case for this type
-is to have an array where each element is another array (and each array can
-have a different length). Another use case is to store an array of variable
-length strings. It is important to note that such an array actually just stores the references to the Python objects and not the objects themselves. Accessing
-an element of the array returns the Python object it refers to.
-
-Data Types added by this extension
-==================================
-
-.. list-table:: Data types
-   :header-rows: 1
-
-   * - Identifier
-     - Numerical type
-     - Size (no. bytes)
-     - Byte order
-   * - ``O`` (uppercase letter o)
-     - 8 (TODO: I assume this is actually a hardware-dependent memory address size?)
-     - address of a Python object
-     - None
