An example about how to write to your metadata. This should provide some
hints to create a line magic to do so:

from IPython.display import Javascript

x = [1,2,3]

def add_metadata(var_name, var):
    js = """
if (Jupyter.notebook.metadata['stored'] ===
undefined){{Jupyter.notebook.metadata['stored'] = {{}}}}
Jupyter.notebook.metadata['stored']['{var_name}']={var_content_serialised}
"""
    return Javascript(js.format(var_name=var_name,
var_content_serialised=var.__repr__()))

add_metadata('x', x)
