"""Renku CLI commands for handling of Knowledge Graph data.

Exporting Knowledge Graph data
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can export part or all of the Renku Knowledge Graph metadata for the
current project using the ``renku graph export`` command.

By default, this will export the metadata created in the last commit in the
project.
If that commit was not a ``renku`` command that creates metadata, it will
produce no output.

.. code-block:: console

   $ renku dataset create my-dataset
   OK
   $ renku graph export
    [
        {
            "@id": "https://localhost/datasets/850e74d6c0204e8c923457a1b9ce52d8",
            "@type": [
            "http://schema.org/Dataset",
            "http://www.w3.org/ns/prov#Entity"
            ],

            [... many more lines ...]

        }
    ]

Here we created a new dataset and then ``renku graph export`` exported the
created metadata as JSON-LD, the default format.

If you want the Knowledge Graph data for the whole project, you can use
``renku graph export --full``. Alternatively, you can get data for a single
commit by using ``renku graph export --revision <git commit sha>`` or by
specifying a range of commits like ``renku graph export --revision sha1..sha2``.

``renku graph export`` currently supports various formats for export, such as
``json-ld``, ``rdf``, ``nt`` (for triples) and ``dot`` (for GraphViz graphs),
which can be specified using the ``--format`` option. For instance,

.. code-block:: console

   $ renku graph export --full --format dot | dot -Tpng -o my_graph.png

would produce a PNG image of the whole Knowledge Graph for the project.

To run validation on the generated output, you can pass the ``--strict``
option, which will check that all the nodes and properties in the graph are
correct and that there isn't anything missing.
