SMART Protocols Ontology: Workflow Module (SP-Workflow)
========================================================================================================================

Overview
--------
SP-Workflow module represents: i) the executable  elements of a protocol; ii) the experimental actions
and material entities that participates in instructions (sample/specimen, organisms, reagents,
instruments);  and iii) the order of execution of the instructions.

.. code-block:: python

    from ontolearner.ontology import SPWorkflow

    # Initialize and load ontology
    ontology = SPWorkflow()
    ontology.load("path/to/ontology.OWL")

    # Extract datasets
    data = ontology.extract()

    # Access specific relations
    term_types = data.term_typings
    taxonomic_relations = data.type_taxonomies
    non_taxonomic_relations = data.type_non_taxonomic_relations
