Dataset Metadata
================

Each ICAT dataset can have metadata associated with it, describing experimental and contextual information. The definitions of these metadata elements are documented in the `ICAT metadata definitions project <https://icat-esrf-definitions.readthedocs.io/en/latest/>`_. Additionally, metadata specific to the experimental techniques and their ontology is described in the `ESRF ontologies documentation <https://esrf-ontologies.readthedocs.io/en/latest/>`_.

BLISS: add dataset or sample metadata
-------------------------------------

For details, see the `BLISS documentation <https://bliss.gitlab-pages.esrf.fr/bliss/master/data/data_dataset_metadata.html>`_. 

In *Python*, `scan_saving` can be accessed from the current BLISS session to read or update dataset metadata:

.. code-block:: python

    from bliss import current_session

    sample_name = current_session.scan_saving.dataset["Sample_name"]
