METADATA
========

Python object: ``phenotypic.schema._metadata.METADATA``

Framework-populated image metadata keys.

These labels are set automatically by the image pipeline (not by the user) and
name the bookkeeping entries on the ``image.metadata`` accessor. Members render
as ``MetadataImage_<Label>`` (e.g. ``MetadataImage_ImageName``) in the
``Metadata`` column family shared with the user-facing experimental tags in
``phenotypic.schema`` (see ``SAMPLE_METADATA`` and siblings).

For the standardized *biological/experimental* vocabulary users supply via the
``--metadata`` CSV, use the experimental-tag enums instead.
