SAMPLE_METADATA
===============

Python object: ``phenotypic.schema._experimental_tags._sample.SAMPLE_METADATA``

Recommended ``Metadata_*`` tags identifying a sample and its provenance.

These distinguish individual biological samples and track where each colony came
from (replicate, clone, source plate/well, library). Members render as
``Metadata_<Label>`` (e.g. ``Metadata_Replicate``) and share the ``Metadata_``
namespace with the other experimental-tag enums. Recommended vocabulary, not a
validator: arbitrary metadata columns are still accepted.
